The Question of Y

We’ve all heard that humans and chimps share up to 98% of their DNA. But new studies are accentuating the differences between humans and chimps. Research into one region of the Y chromosome has shown a difference of more than 30%. The researchers originally believed that human and chimp Y chromosomes would differ very little, based on their belief that both inherited their Y chromosomes from a common ancestor.

They are now looking for mechanisms to explain the apparent “rapid evolution” of the Y chromosome that allegedly caused the 30% difference. They are not, however, rethinking their evolutionary presuppositions. Their initial conjecture is that chimps lost several genes after evolving from their common ancestor with humans.

Creationists admit one thing about a possible relationship between chimps and humans: they have the same Designer. And that presupposition is not open to change.
