Based on what evidence? Or just your "feeling?"
- domnomnom 7y agoI think you’re confused on how evidence and burden of proof works. These studies use genetic differences as a proxy for differences in periods of time. If there was a context that caused a high rate of genetic change, it would appear to be an organism with a lineage that spanned across a large time period.
