The earlier timeline means that the three species of humans co-existed on the planet for around 800,000 years, much longer than previously thought, perhaps interacting and interbreeding in that time.

But if wild populations with variations in genotype keep interbreeding, Dobzhansky knew, a new species would never be formed: a species, after all, is fundamentally defined by its inability to interbreed with another.
