  • What is Genetic Drift?
    Oct 23 2025
    Scientist throw around words and phrases that are sometimes hard to understand. This is not one of them. Genetic drift is an easy concept. Dr Rob brings up the example drift among of human mitochondria, perhaps the most extreme form anyone has ever seen. And, since natural selection is generally weak, genetic drift overwhelms selection at critical junctures during development. This has profound implications for the creation-evolution debate, but first, the explanation... Source paper under discussion: Árnadóttir et al. 2024, The rate and nature of mitochondrial DNA mutations in human pedigrees, Cell 187(15):3904-3910. Fig 1: Mutant mitochondrial frequencies in child (y) vs mother (x), from the supporting data of the paper above. Fig 2: Histogram of frequency changes from mother to child, same source as above. Fig 3: Histogram data for each frequency bin in the mother (legend) vs child (x). Same source as above.

  • When did Eve live?
    Sep 30 2025
    One woman is the ancestress of all living people. They call her Eve. Is she the Eve of the Bible? How long ago did she live? Join Dr Carter as he explains how scientists struggle to assign a date to Eve. It may come as a surprise, but the 'date' is based on questionable assumptions and debatable philosophy. All we can know is that the mutation rate is quite high and the mutation removal rate is quite low. Thus, science tells us that Eve lived not many thousands of years ago.
