Adam, Eve, and the Genome

Some very conservative, quasi-literalist Christians are questioning the Biblical account of creation, based on the evidence of our genes:

Some conservative scholars are saying publicly that they can no longer believe the Genesis account. Asked how likely it is that we all descended from Adam and Eve, Dennis Venema, a biologist at Trinity Western University, replies: "That would be against all the genomic evidence that we've assembled over the last 20 years, so not likely at all."

Venema says there is no way we can be traced back to a single couple. He says with the mapping of the human genome, it's clear that modern humans emerged from other primates as a large population — long before the Genesis time frame of a few thousand years ago. And given the genetic variation of people today, he says scientists can't get that population size below 10,000 people at any time in our evolutionary history.

To get down to just two ancestors, Venema says, "You would have to postulate that there's been this absolutely astronomical mutation rate that has produced all these new variants in an incredibly short period of time. Those types of mutation rates are just not possible. It would mutate us out of existence."

See, the thing about Darwin's theory is that the more we learn, the better it gets. When he first dreamed up natural selection, nobody knew about genes or mutations or anything about the statistics of evolution. Now we know a lot about those things, and with every new discovery Darwin looks better. You cannot take science seriously and deny evolution; the only way to maintain special creation is to deny validity to science as a way of learning about the world. Accept science in any way, and if you are consistent you end up with evolution. And where does that leave Biblical literalists?

"The evolution controversy today is, I think, a Galileo moment," says Karl Giberson, who authored several books trying to reconcile Christianity and evolution, including The Language of Science and Faith, with Francis Collins.

Giberson — who taught physics at Eastern Nazarene College until his views became too uncomfortable in Christian academia — says Protestants who question Adam and Eve are akin to Galileo in the 1600s, who defied Catholic Church doctrine by stating that the earth revolved around the sun and not vice versa. Galileo was condemned by the church, and it took more than three centuries for the Vatican to express regret at its error.

"When you ignore science, you end up with egg on your face," Giberson says. "The Catholic Church has had an awful lot of egg on its face for centuries because of Galileo. And Protestants would do very well to look at that and to learn from it."
