= Mitochondrial DNA mutates faster than nuclear DNA
Wikipedia mentions "Since animal mtDNA evolves faster than nuclear genetic markers" with a few sources.
Some sources:
* <Power, Sex, Suicide by Nick Lane (2006)> page 361 mentions:
\Q[While nuclear DNA can barely distinguish between chimps and humans, the mitochondrial clock ticks fast enough to reveal differences accumulating over tens of thousands of yearss]
so this property is also important for the <human mitochondrial molecular clock>.
