I'm a dilettant (=non-biologist), but I thought Gould and Eldridge estimated
that the speciation period was typically around 10% of the species' "life".
Given that homo sap sap is around 500,000 years old, and that we could expect
on purely biological grounds that the species would survive at least 5
million years, perhaps we are still in the process of speciating?
