In a new post at UD, Denyse O’Leary quotes an article from The Scientist (which she misattributes to Science):
Populations of Escherichia coli grown in the lab quickly evolve tolerance when exposed to repeated treatments with the antibiotic ampicillin, according to a study published today (June 25) in Nature. Specifically, the bacteria evolved to stay in a dormant “lag” phase for just longer than three-, five-, or eight-hour-long treatment courses, before waking up and growing overnight until the next round of treatment began.
For phoodoo. To discuss the Origin of Life.
Just to offer my own thoughts on the matter, as a red rag for phoodoo’s contempt, I think that all theories that require some kind of ‘takeover’ of one genetic system by another are dead in the water. That includes the Cairns-Smith ‘dust’ notion, but also ‘proteins-first’ theories.
Over at Uncommon Descent KirosFocus repeats the same old bignum arguments as always. He seems to enjoy the ‘needle in a haystack’ metaphor, but I’d like to counter by asking how does he know he’s not searching for a needle in a needle stack?
There is then of course much smugness and back-pating, along with “Notice some chirping crickets?”
Well, let’s see what happens in an environment where crickets aren’t moderated or banned…
On the Counterintuitive evolutionary truths thread, I expressed amazement at the sheer number of distinct kinds of intragenomic conflict that have been discovered by science. In response, Allan Miller recommended the 2006 book Genes in Conflict, by Austin Burt and Robert Trivers. Burt’s name is unfamiliar to me, but Trivers is famous for proposing the theory of reciprocal altruism.
I ordered the book (28 for the paperback), and so did Gralgrathor, so I thought it would be nice to have a discussion thread for the book as we read it. Anyone is welcome to join in, of course, whether or not you are reading the book.
Scordova has posted something that caught my attention at UD.
It’s up to ID proponents to demonstrate a few incontrovertible instances where design is uniquely fruitful for biology. Scientists without an inordinate attachment to Darwinian evolution (and there are many, though this fact is not widely advertised) will be only too happy to shift their allegiance if they think that intelligent design is where the interesting problems in biology lie.
At UD this claim was made:
Neither rocks nor human brains dream. Only the mind/soul dreams. The human body is a diving suit, specifically designed to be operational by conscious/subconscious intent – meaning, an individualized consciousness (mind/soul) can use it to functionally operate in the physical world. A rock has no such capacity for service.
I have to wonder how what this video depicts can be squared with that.
Hypoxia – 4 of spades
During hypobaric chamber, or altitude chamber training, #14 displayed symptoms of hypoxia, after exceeding his time of useful consciousness (TUC).
In the Roger Scruton on altruism thread, some commenters have expressed confusion over the evolutionary explanation of altruism in ants. If workers and soldiers leave no offspring, then how does their altruistic behavior get selected for?
I worry sometimes that this is me.
but in the spirit of the free exchange of ideas, I thought I’d offer a thread where nothing is off-topic.Think carefully before you Continue reading
Kairosfocus has a new OP at UD entitled Putting the mind back on the table for discussion. His argument begins thus:
Starting with the principle that rocks have no dreams:
Reciprocating Bill points out that since KF denies physicalism, he has no principled basis for denying the consciousness of rocks:
If the physical states exhibited by brains, but absent in rocks, don’t account for human dreams (contemplation, etc.) then you’ve no basis for claiming rocks are devoid of dreams – at least not on the basis of the physical states present in brains and absent in rocks. Given that, on what basis do you claim that rocks don’t dream?
Needless to say, KF is squirming to avoid the question.
