Evolution Reflected in Development

Below is an image of the developmental path from human conception to adult in comparison with evolutionary path from prokaryote to human.

Unlike Haeckel’s biogenetic law with its focus on physical forms, the comparison above also concerns activity, lifestyle and behaviour. Comparative stages may be vastly different in detail, but the similarity of general lifestyles and consecutive stages are there to be observed.

Human life begins in an aquatic environment. Toddlers gradually learn to walk upright from a previous state of crawling and moving around on all fours. The brains of children develop through daily interactions and experiences. This brain development accompanies the child’s increasing ability to achieve complex manipulation skills using hands that have been released from the task of providing support and locomotion, and also the practice of producing sounds using the various muscles of the mouth. Well developed brains allow for rational thinking and the creative use of language.

Human minds have brought about technological advances which have allowed human activities to engulf the planet. Signs of intelligent human activity are evident a good distance beyond the earth spreading ever further out into space.

The various forms of extant animals and all other life forms have evolved as an integral component of the living earth and the whole forms a dynamic system.

The various animal forms should be studied in the context of the complete system in both time and space.  Conditions would have been very different prior to the terrestrial colonization of earthly life In all probability none of the present aquatic animals would bear any resemblance to the aquatic ancestors of humans and other higher vertebrates save that at some stage they all require an aquatic environment for their continued existence.

From a point of view which regards physical organisms as the individual expressions of overarching general forms, the evolution of cetaceans need not have involved moving to the land only to return to the water at a later time. They may have reached the mammalian stage of evolution but in a way that was suitable for an aquatic lifestyle. They adopted the archetypal mammalian form in a way that suited an animal living in an aquatic environment and there would be no need to posit a terrestrial stage in their evolution.

It’s my belief that higher consciousness is ever present. Evolution is the process whereby higher forms of consciousness descend from the group level to the individual level. The most fully developed individual consciousness which I am aware of on earth can be found in humans but it is still rudimentary compared to the higher level group consciousness.

Plasticity is a fundamental feature of living systems at all levels from human brain development to the radiation of multicellular life. Paths are formed by branching out and becoming fixed along certain lines. It would be impossible to forecast specific paths but, nonetheless, there is a general overall direction.

Now that biological life has reached the stage where social organisms have become individually creative and rational, the all encompassing Word is reflected in single beings. This could not have come about without preparation and the evolution of earthly life is the evidence of this preparation. We, as individuals, are only able to use language and engage in rational thinking because our individual development has prepared us to do so. Likewise humanity could not arrive at the present state of culture without the evolutionary preparation in its entirety.

Focussing in at the lower level gives a picture of ruthless competition, of nature “red in tooth and claw”. But from a higher vantage point life benefits from this apparent brutality. For instance if a sparrowhawk makes regular hunting visits to a suitable habitat in your neighbourhood it signifies that this environment supports a healthy songbird population. In the case of the continued evolution of physical forms, survival of the breeding population is more important than any individual’s survival. In the evolution of consciousness the individual is the important unit.

I think it is a mistake to see biological evolution as a blind random groping towards an unknown and unknowable future.

  1. Corneel: I do not understand that. Why not?

    Not being either a determinist or a philosopher, my understanding may be incorrect but under strict determinism, outcomes from identical scenarios will always be the same. Choice is predetermined.

    You get up in the morning and you decide to go for a run. It’s true that if we rewind time and start again from the exact same situation you will be making identical decisions. But if the external factors were different (for example, it is raining now) you may decide to stay at home. Is that not a free choice? Why not?

    It is a free choice. I think strict determinism is wrong in its conception.

    Where are the bleedin’ philosophers when you need them BTW?

    Exercising their free choice to philosophise elsewhere.

  2. phoodoo: Tell all your atheists friends how wrong they are Alan.

    Atheism isn’t a consideration when I choose (!) to maintain friendships. And “free will” is not a hot topic of conversation.

  3. The nucleus does not significantly affect the migratory trajectories of amoeba in two-dimensional environments

    One of the key issues in cellular migration is the role of the nucleus in the regulation of the locomotion system. The nucleus, the main cellular structure containing genetic information and gene regulatory machinery, has long been postulated to play an essential implication in migration, but this role is starting to be understood only very recently. In fact, shortly after the preliminary version of our study was deposited in bioRxiv.org16, a new work has shown that the nucleus is not essential for migration on flat two-dimensional (2D) surfaces17. In the work of Graham and coauthors (2018) the nucleus was removed from fibroblasts and endothelial cells. They observed that the cytoplasts i.e., cells without nuclei, correctly polarize and migrate along different 2D gradients in a similar way to intact nucleated cells showing that their migration abilities are not reliant on the presence of the nucleus.

    If the DNA is running the show how is this possible?

  4. Corneel,

    No wonder you ,a d Alan and Rumraket and the like are materialists-you don’t even know what it means.

    Its like someone saying they believe in social justice and equal rights for all. That’s why they belong to the Nazi party and support the ideas of Hitler. They also support Sharia law.

  5. phoodoo: I am not as dismissive of you as I am of Alan, but it has nothing to do with rewinding anything, and it being the same or different. That is totally beside the point. It is about what you perceive vs. what materialism implies.

    I perceive my decisions to be as freely made as you perceive them to be. Whether materialism (actually determinism) is true does not change that. Why does the concept of materialism give you the idea that you are not free to make decisions?

  6. Alan Fox: Not being either a determinist or a philosopher, my understanding may be incorrect but under strict determinism, outcomes from identical scenarios will always be the same. Choice is predetermined.

    Sure, but why does that make it not free? You want to go on that morning run, do you not?

    Alan Fox: It is a free choice. I think strict determinism is wrong in its conception.

    Not being a philosopher, I honestly would not know. But if strict determinism were shown to be true it wouldn’t bother me in the slightest.

    Alan Fox: Exercising their free choice to philosophise elsewhere.

    I miss having walto around. Perhaps KN will show up and enlighten us.

  7. Corneel: Whether materialism (actually determinism)

    Oh my goodness.

    Maybe you should research why virtually every famous atheist on the planet understands the implications of materialism. Its like descibing a swimming pool to people who don’t even know what water is.

    Stunning.

  8. phoodoo: Oh my goodness.

    Maybe you should research why virtually every famous atheist on the planet understands the implications of materialism.Its like descibing a swimming pool to people who don’t even know what water is.

    Stunning.

    This is a favourite posture of yours beyond which you never progress.

  9. Corneel: Sure, but why does that make it not free? You want to go on that morning run, do you not?

    Free choice is constrained. Arthritic knees constrain me from running these days, much as I want to. 🥺

  10. phoodoo: No wonder you ,a[n]d Alan and Rumraket and the like are materialists-you don’t even know what it means.

    Perhaps, but you seem to be unable to explain why materialism implies that choices and decisions do not exist.

    Let me turn the tables: if your decisions and choices can be completely different, even opposite, in completely identical situations (as they must be under libertarian free will), then what relevance do they have? Will your decisions not be completely inconsistent, as they are independent of external factors?

  11. Corneel: I miss having walto around. Perhaps KN will show up and enlighten us.

    I miss walto too. Fingers crossed on a KN fly-by.

  12. Alan Fox: Free choice is constrained. Arthritic knees constra[i]n me from running these days,ugh as I want to.

    That sucks. Hope you still have other ways to get around. How’s biking?

  13. Corneel,

    Do you know of any contemporary well known atheists who advocate this free will concept you believe exists?

    You know, one reason why they are well known is because other atheists believe them.

  14. phoodoo: Do you know of any contemporary well known atheists who advocate this free will concept you believe exists?

    You know, one reason why they are well known is because other atheists believe them.

    I do not closely follow atheist writings, phoodoo. I do not care: being an atheist really is not a part of my identity.

    But I do believe I have free will. When you tell me this is an illusion, I expect you to tell me why.

  15. Corneel: I do not closely follow atheist writings, phoodoo. I do not care: being an atheist really is not a part of my identity.

    So you don’t know anything about the topic, you don’t care about the topic, but you think it is my fault that I have not explained to you what these concepts mean?

  16. Corneel: That sucks. Hope you still have other ways to get around. How’s biking?

    Can still enjoy a good walk and can swim when it’s too hot. Cycling is a bit of an art-form here. Everyone on a bike has the right clothing and physique, plus the terrain is demandingly hilly.

  17. phoodoo: So you don’t know anything about the topic, you don’t care about the topic, but you think it is my fault that I have not explained to you what these concepts mean?

    Butting in. It’s that you exude some kind of superiority. I’m curious how you justify it and how “materialism” and “atheism” are so triggering for you.

  18. Corneel,

    If someone told you they use their mind to decide if their fingernails will grow or not, would you believe them?

    What about if someone said they can use the power of their mind to cure other people of homosexuality-would you believe this? Why not, its possible right? Because if you rewinded the tape, the next time they might not use their mind to do this.

  19. Alan Fox: It’s that you exude some kind of superiority.

    You have been attempting to have all kinds of influence on what people write here for quite some time Alan, that is one reason I have no problem being critical of you. the same goes for Jock. Your actions have been repugnant in my estimation. You have a long history of this.

    If anyone is triggered it is you. I am just telling you the facts of what philisophical stances imply. If you don’t understand that, or are unwilling to accept those implications, that is not really my problem. If you have a problem with it, I suggested you could take it up with almost every influential person who has ever studied the topic.

    To say, I believe in complete materialism, but I also believe in immaterial control of physical entities, then your position is simply logically nonsensical. Of course you can have all the nonsensical beliefs you want (I don’t care at all)-but don’t expect people to refrain from pointing out to you that its entirely illogical.

  20. phoodoo: Of course you can have all the nonsensical beliefs you want (I don’t care at all)-but don’t expect people to refrain from pointing out to you that its entirely illogical.

    That’s what I was hoping you might do. Whenever you are ready.

  21. Alan Fox: ’m curious how you justify it

    He doesn’t. Attempts to do that would expose him to criticism, and phoodoo is not about actual thinking and argument, he’s only about this butthurt feeling he has that compels him to keep coming back out of some sense of pride because someone somewhere insulted him somehow. Free will is part of it, but mostly all of this has to do with fitness. Free will must exist because, to phoodoo, if it does not then his life is meaningless and total moral and existential nihilism inexorably follows.

    Now all that said, phoodoo hates the concept of fitness and it’s relation to natural selection most of all, because he himself can’t help but interpret a sort of ethical or moral value-judgement into the idea that one thing might have lower reproductive fitness than another.
    If you spend some time trying to discuss this with him you discover that it is as if phoodoo, at least implicitly, actually believes that differences in reproductive fitness would morally justify mistreatment and discrimination of others. He will never explicitly state this, but he often argues as if he agrees that we should sterilize or exterminate the handicapped, or people of other ethnicities.

    Now it is ironic that because of phoodoo’s entirely understandable rejection of mistreatment and discrimination(they are of course the boogey man he will pull out and try to tarnish evolution with), it leads him to attack the concept of fitness, instead of just attacking the mistreatment and discrimination. He does not appear to understand that one thing being real (variations in reproductive fitness) does not make it morally justified to mistreat people on that basis.

    He will cry and whinge that evolution is supposedly responsible for things like eugenics and nazis until the end of time, but if you ask him how carriers of different alleles having differences in reproductive fitness justifies mistreatment or discrimination, you will not get any answer, because he doesn’t like admitting that it does not. Because if he were to admit that, he would also then have to admit that Nazism and eugenics aren’t actually entailments of evolution, and thus their historical occurrences cannot be laid at the feet of evolution, nor do they actually affect whether evolution is true or not.

    He will always be arguing under the pretension that it does, thus effectively appearing to agree with the very concepts he rail against.

  22. phoodoo: I am just telling you the facts of what philisophical stances imply.

    You’re not. You keep dodging on facts.

  23. phoodoo: I am just telling you the facts of what philisophical stances imply.

    No, you are asserting that they imply it, but you never show it to be a fact that they imply it. It’s just something YOU imply.

  24. Rumraket: It’s just something YOU imply.

    Haha…right I made it up. Then I taught it to Hawking, Krauss, Dawkins, Sagan, Sapolsky, Harris, Pinker, Dennett, Greene, Coyne, Shermer, ….

  25. phoodoo: Haha…right I made it up.Then I taught it to Hawking, Krauss, Dawkins, Sagan, Sapolsky, Harris, Pinker, Dennett, Greene, Coyne, Shermer, ….

    None of whom are nihilists, or have shown that moral or existential nihilism follows from materialism.

    So, please give the argument. You think nihilism follows from materialism. Show it.

  26. So, to be clear, materialism leads to existential nihilism because all our choices are illusions and there is no such thing as free will whereas theism, where all our choices are also illusions as they known in advance to a deity before we make them, does not?

    Is that about the size of it?

  27. Rumraket: So, please give the argument. You think nihilism follows from materialism. Show it.

    That deserves it’s own thread. If phoodoo actually makes an argument for something that’d be quite something indeed.

  28. OMagain: That deserves it’s own thread.

    Phoodoo is of course welcome to post one. I’m tempted, on discovering that Arthur Eddington was an advocate of indeterminism, to put up an OP.

  29. The illusion that elections have consequences is a hard one to ignore or doubletalk away.

  30. Alan Fox:
    phoodoo,

    Only Dennett is a philosopher of note and he does not advocate determinism.

    DENNETT’S REDEFINITION OF FREE WILL
    Dennett defends a particular form of determinism known as compatibilism. This is the view that the concept of free will should be redefined so that it no longer involves a free choice among alternatives and can thus be made compatible with the mechanist/reductionist model of the universe.

    Only if you play word games.

  31. (Phys.org)—When biologist Anthony Cashmore claims that the concept of free will is an illusion, he’s not breaking any new ground. At least as far back as the ancient Greeks, people have wondered how humans seem to have the ability to make their own personal decisions in a manner lacking any causal component other than their desire to “will” something. But Cashmore, Professor of Biology at the University of Pennsylvania, says that many biologists today still cling to the idea of free will, and reject the idea that we are simply conscious machines, completely controlled by a combination of our chemistry and external environmental forces.

    In a recent study, Cashmore has argued that a belief in free will is akin to religious beliefs, since neither complies with the laws of the physical world. One of the basic premises of biology and biochemistry is that biological systems are nothing more than a bag of chemicals that obey chemical and physical laws. Generally, we have no problem with the “bag of chemicals” notion when it comes to bacteria, plants, and similar entities. So why is it so difficult to say the same about humans or other “higher level” species, when we’re all governed by the same laws?

    No causal mechanism

    As Cashmore explains, the human brain acts at both the conscious level as well as the unconscious. It’s our consciousness that makes us aware of our actions, giving us the sense that we control them, as well. But even without this awareness, our brains can still induce our bodies to act, and studies have indicated that consciousness is something that follows unconscious neural activity. Just because we are often aware of multiple paths to take, that doesn’t mean we actually get to choose one of them based on our own free will. As the ancient Greeks asked, by what mechanism would we be choosing? The physical world is made of causes and effects – “nothing comes from nothing” – but free will, by its very definition, has no physical cause. The Roman philosopher and poet Lucretius, in reference to this problem of free will, noted that the Greek philosophers concluded that atoms “randomly swerve” – the likely source of this movement being the numerous Greek gods.

    Today, as researchers gain a better understanding of the molecular details underlying consciousness, some people think that we may discover a molecular mechanism responsible for free will – but Cashmore doesn’t think so. Such a discovery, he says, would require a new physical law that breaks the causal laws of nature. As it is, the only “wild card” that allows any room for maneuvering outside of genetics and one’s environment is the inherent uncertainty of the physical properties of matter, and even this stochastic element is beyond our conscious control. (However, it can help explain why identical twins growing up in the same environment are unique individuals.)

    To put it simply, free will just doesn’t fit with how the physical world works

    I made it up. Ha.

    I wonder if you guys have read any books that were written in, say, the past 2000 years.

  32. Alan Fox:
    phoodoo,

    Only Dennett is a philosopher of note and he does not advocate determinism.

    I am exceedingly frustrated by >Daniel Dennett’s response to sam harris’ recent book on free will.

    It serves as the most elaborate, learned, and desperate hand-waving I’ve ever witnessed. It was such a weak argument that it looked more like an example that a brilliant philosophy professor, like Daniel Dennett, might use to highlight poor arguments to his students. Sadly it wasn’t a strawman used for instruction—it was his real position.

    Here’s what he basically said:

    It seems like we make choices, so we do.
    It’s useful to hold people responsible for their actions, so moral responsibility is real.
    I just saved you ~30 minutes of exasperation. But let’s take it piece by piece.

    And

    Harris:

    However, the ‘free will’ that compatibilists defend is not the free will that most people feel they have. (p16)
    Dennett:

    First of all, he doesn’t know this. This is a guess, and suitably expressed questionnaires might well prove him wrong.
    Seriously? Do you really think that, in a country where only half of the population believes in evolution, any significant percentage of people are going to have an advanced belief in free will?

    You should like Dennett, Alan, since you don’t understand what he is saying:

    Maybe many people, maybe most, think that they have a kind of freedom that they don’t and can’t have. But that settles nothing. There may be other, better kinds of freedom that people also think they have, and that are worth wanting. (Dennett, 1984)

    https://danielmiessler.com/blog/dennett-wrong-freewill/

  33. In a brief video on the website Big Think, philosopher Daniel Dennett accuses neuroscientists of corrupting the public by telling people they don’t have free will. Rather than addressing the question of whether or not free will exists, Dennett questions whether or not people are better off believing in free will, regardless of the accuracy of this belief. However, the consequences of free will skepticism are not always negative. And experts in science, philosophy and other specialized fields should share their well-founded opinions with the public and help guide public behavior in light of this shared knowledge.

    I just made it up…..

  34. Free Will Skepticism.

    Hmmm, maybe I will make that the name of a new blog, since it appears I just invented the phrase. At least to the scholars here it appears that way.

  35. phoodoo,

    And again. Not Dennett. Is there a problem with finding a quote of Dennett himself? I have a few of his popular books on Kindle. I’ll have a look when I have time.

  36. And still nothing about how nihilism is supposedly an entailment of materialism from phoodoo. He’d deliberately ignoring it because he knows he can’t show that it does.

  37. phoodoo: Me: I do not closely follow atheist writings, phoodoo. I do not care: being an atheist really is not a part of my identity.

    phoodoo: So you don’t know anything about the topic, you don’t care about the topic, but you think it is my fault that I have not explained to you what these concepts mean?

    You really should stop revelling in your own confusion. We were discussing materialism. It is you who conflates that with atheism (and evolutionism).

    Instead of pasting large swathes of text, why don’t you try to distill the arguments you believe are being made into a few sentences of your own? That would be more instructive to both you and me.

  38. Alan Fox: Dennett himself:

    I really like that fragment. If a car comes at you at high speed and you step aside saving your own life, it is irrelevant that this chain of events was already determined. What matters is that you chose to step aside. That is free will.

    I also like the comment about how INdeterminism renders the concept of free will vacuous. If your decisions are not predictably informed by the external factors they are supposed to be a response to, then they are just whims.

  39. Rumraket: And still nothing about how nihilism is supposedly an entailment of materialism from phoodoo. He’d deliberately ignoring it because he knows he can’t show that it does.

    Isn’t it a bit weird to tell other people they ought to be nihilists? If I were proselytizing, I’d use a different tack.

  40. Corneel,

    Indeed. It seems some theoretical physicists want to claim biology reduces to physics. I think they are mistaken before they start in that fundamentally physics is indeterminate (anyway it’s non-disprovable) whereas Dennett says it doesn’t matter if they’re right.

  41. phoodoo: If someone told you they use their mind to decide if their fingernails will grow or not, would you believe them?

    Nope

    phoodoo: What about if someone said they can use the power of their mind to cure other people of homosexuality-would you believe this?

    Nope. Also: what’s to cure? Homosexuality is not a disease.

    phoodoo: Why not, its possible right? Because if you rewinded the tape, the next time they might not use their mind to do this.

    Sorry, but I do not see the point of your thought experiment. If we assume strict determinism, then if you rewind the tape than events will unfold identically. If we assume people have libertarian free will, then I still do not see why I should be dealing with alternative timelines whenever someone makes a nonsensical claim.
