From the article:

“Recent research (notably cross-species comparisons of gene sequences rendered non-functional by mutations) has greatly strengthened the case that humans and chimpanzees share a common ancestor. A creationist speaker in Baltimore shrugged such discoveries off, declaring that ‘science changes, but the word of God never changes.’

A trickier controversy has been triggered by findings from the genome that modern humans, in their genetic diversity, cannot be descended from a single pair of individuals. Rather, there were at least several thousand ‘first humans’. That challenges the historical existence of Adam and Eve, and has sparked a crisis of conscience among evangelical Christians persuaded by genetic science. “
