Re: ARE SEA TURTLES THE CURRENT DINOSAURS?

The living descendants of the dinosaurs are birds. All birds have a common ancestor which arose from the maniraptors, which are coelurosaurs, which are therapods, which are dinosaurs. We know that birds descend from this group because of their morphology; not only do they have very similar skeletons...

Re: Common ancestor question

Short answer: Yes, it would be a species — although that comes down to numerous individuals, each of whom can fully claim to be a common ancestor. The tricky thing to remember about ancestry is that any given organism's line of descent has a good chance of spreading throughout an entire population, ...

I'm sorry, but no "fossils" do I see.

It seems like an example of this phenomenon:

Re: weight lifting, repetitions & evolution theory

Is this kind of what you meant? Yep. Creatures aren't boxes of "limited" abilities, where it can do X and nothing more. A dog with the ability to chase and catch a squirrel (directly benefiting it) also has the ability to chase and catch a frisbee (indirectly benefiting it). I remember on...

Re: Marine Invertebrates and Evolution

For reasons having to do with sediment and other stuff I don't completely understand, marine environments are much more "fossil-friendly" than other places, so it is indeed the case that the majority of fossils are of marine animals. However, it is not correct that we lack marine transitio...

Improbability and testability

Anti-evolution people, such as creationists and intelligent design folks, often use improbability to argue that a given structure could not have evolved. These arguments are usually countered in two ways — by demonstrating a pathway whereby the structure could have developed, and by questioning the ...

I just read the Wikipedia article on the Golgi tendon reflex, mentioned in the reply above, and it looks like a very good example of one of those "overriding instinct" things I was talking about. (Maybe.) Just like a certain level of pain will cause you to move whether you want to or not, ...

Re: weight lifting, repetitions & evolution theory

Popular-level books and news stories in areas like evolutionary psychology can sometimes leave the reader with a mistaken impression that all humans are "evolved for" X, where X is the specific environment in which our species arose. I'm not an expert , but here's one of the things I under...
