> The second one is an observation about the rate at which the different genomes on Earth have changed over evolutionary history. When extrapolated back into the past, this evolution rate of genomes suggests that the current lineage of life on Earth might be at least 10 billion years old, I wonder to what extent the scientists who study these evolutionary clocks are able to factor in increasingly (or decreasingly) capable DNA replication and repair mechanisms. More faithful DNA replication and repair would artificially show a slower rate of genome evolution.
