There is no Y Chromosome Clock

Biblical Genetics

The 'molecular clock hypothesis' is critical for evolutionary theory. If it fails, many evolutionary speculations will fall as well. Yet, there is abundant evidence that mutations in the Y chromosome have happened at different rates among different people groups. If this is true, nobody an know how long ago 'Y Chromosome Adam' lived. Notes: My Review of Nathaniel Jeanson's Traced Ding et al. 2021. Mutation Rate Variability across Human Y-Chromosome Haplogroups. Mol Biol Evol 38(3):1000-1005.
