Is it rare to unify the molecular data with fossil finds?
This is a very rare occurrence. This is virtually unknown. We have 18 orders of mammals living today: the horses, the artiodactyls, the whales, the rodents, the rabbits-18 of these groups. They can, most of them, be traced back to the beginning of the Eocene, and then we mostly don’t know how they’re connected. And so our molecular colleagues are telling us many answers, some of which disagree with each other, none of which we can fully believe because we don’t have evidence from fossils that tie them together. So this is a very special case to be able to tie the groups together with fossils too. It’s what we’ve been working, working, working to get for all these groups, and at least now we’ve got it for one. Were you surprised that it should happen with whales? DNA is not an ideal evolutionary document and the reason is partly because the code is too simple. It’s very long, so it gives us lots of information, but the letters coded in it are too few to convey a lot of information, so i
- Do these expectations about the dissemination of data and biological materials apply to all applications studying molecular genetics of addiction in humans?
- Why is it important to use both anatomical and molecular evidence, as well as the fossil record?
- Why can the Plugin get or put data (formula, molecular weight etc.) in Netscape 6.0?
