I didn't know that. The skeleton is definately different.
I worry that we don't know as much about DNA as we think. I am beginning to think that there's more and we're missing something.
I ave thought the same thing myself for a long time. There is something wrong with the scenarios being postulated.
I agree completely.
Simple concept, and yet from it there is nearly infinite variation to make molecular machines (protein enzymes) that do everything living things do.
The big breakthrough in biology will be figuring out just how far down the rabbit hole you have to go as far as interlocking systems of control and regulation, some of which I am sure we have no idea about yet, just as we didn't know much about how much little micro RNA’s were doing until a couple decades ago.
