On another forum the claim was strongly put that the anatomy of theropod dinosaurs was so similiar to moderrn birdds that its excellent evidence for birds to have evolved from dinosaurs. So some evolutionists say birds today are really the end game of dinosaur evolution.
yEC say birds wewre created in their kinds on creation week and were on the ark in kinds. So were creatures we call dinosaurs and so these theropod ones.
So its impossible birds evolved from theropod dinos.
The only evidence they have is the anatomy of theropods . Some say they had feathers.
I have another hypothesis. That it is only a convergence of bone structures(anatamy) for the same needs. It is not that these dinos have bird bones but thart birds don’t have bird bones. they both only have bones to join body with physics. the theropods needed to be liught on their feet and the only answer is size and structure of bones to allow this. birds have the same need and so have the same bones. Yet its physics that determoines the bone structure and not a biological ancestry. there is no ancestry. they were created in whole right away. Perfect. its just the right and only conclusion .
This theme is common in nature. in fact i deny their are dinosaurs as a group. they are just kinds of creatures that might have some like traits. likewise no mammal or reptile group.
The theropods would be a later adaptation but they had the same problems and needs. to move quickly with light bodies. Variety’s might become big like our ostriches but special cases.
the point here is that classifying biology by likeness is not demanding as a conclusion. Convergence is a great theme in biology and so neither theropods or birds have bird bones. they just have suitable bones for like needs but never evolved from each other.
