The DNA of humans and chimps is 98.8% identical.

The percent difference between genomes of species is one of those tricky measures that doesn't really give good intuition. I find it much more useful to think in terms of the time since two species shared a common ancestor.

e.g. For humans and chimps, that's several million years. For Sumatran and Siberian tigers, it's around a hundred thousand years.

So not that far away since modern humans began splitting up into separate subgroups outside of Africa? Of course there have been quite a bit of intermixing since then (more so in Eurasia than the more isolated parts of the world before the modern times, though)

What percentage of DNA do all mammals share? And what all mammals except platypus?
