Human gene mutations “arose in the last 200 generations”

DNA

We at Creation Ministries International have periodically pointed out that, from a biblical perspective, there have only been about 200 human generations since time began. (e.g. Creation 31(2):18–19, 2009; The Non-Mythical Adam and Eve!.) In that light, consider these recent findings by evolutionary geneticists, who studied more than one million mutations, or changes to our DNA code, found across human populations.

"Most of the mutations that we found arose in the last 200 generations or so," said Joshua Akey of the University of Washington. He and his co-researchers found that of the mutations likely to be harmful, 91% emerged in the past 5,000 years. Many of these have only existed for the past thousand years.

Echoing Akey's statements, population geneticist Alon Keinan of Cornell University said: "Humans today carry a much larger load of deleterious variants than our species carried just prior to its massive expansion just a couple hundred generations ago."

These observations match the Bible's declaration of a world "in bondage to decay" since Adam sinned (Romans 8: 19–22). Evolutionary geneticists belatedly realized that the rate of degradation of the human genome poses huge problems for the evolutionary timeline.?
