"I have approximate answers and possible beliefs and different degrees of certainty about different things, but I'm not absolutely sure of anything..." (Richard Feynman)
Craig Venter might be a "maverick scientist" and I do not agree with the attempts to patent biological organisms. Nevertheless I agree very much with the positions he takes in the Dimbleby Lecture, blaming the western societies for having lost their enthusiasm for science and for not understanding that science will be the key lever to tackle the problems of the world
" Oh, it's so refreshing, after being told all your life that it is virtuous to be full of faith, spirit and superstition, to read such a resounding trumpet blast for truth instead. It feels like coming up for air."
"Returning to the original question of Darwinism and metaphysics, I have argued that even the assertion of the special creation of organisms is not incompatible with the scientific theory of evolution, which explains how organisms evolve now, and that it is incompatible with the scientific fact of phylogeny only under the assumption that actualism is not just normative for scientific reconstructions but true of the real world. There may just be a sense in which scientific facts are not historical facts.
I think that Steven Pinker's theories are an important part of a keyset to rethink the concepts of "Freedom and Progress". The existence of a "human nature" also justifies something as a concept of "humanity" but thought very severly only in a "non-transcendental"way. But there are global human values - from evolution and civilization.
Humanity might have only one origin. It might have gone also through this famous bottleneck (100.000? years) ago, that left only a few thousand of individulals. The neolithic revolution happened in several places on the earth idipendently (see Jarred). Civilization seems to have been born twice between 5000 and 3000 bc. The Egyptian civilation is impressing. Already 5000 BC kingdoms were existing in Northern and Southern Egypt. They were united in 3000 bc starting with the old kingdom.
