Re: Extra precise?
Short answer: life is a competition in which the weapons continually have to evolve to meet changing circumstances.
Longer answer; over time the environment of the surface of the Earth has changed dramatically, with Ice Ages and warm periods, and continental drift. This has resulted in extinctions and the evolution of new species. The human race (sapiens sapiens) very nearly went extinct in the Mesolithic (we may all be the descendants of just a few hundred South Africans, with a small intermix of Neanderthal and Denisovans for some population groups) so perhaps one tsunami or big volcano eruption at the right moment and it might be a Neanderthal writing this, or there might be no humans at all. Population now tells us nothing about the fitness of a species at some time in the past.
