What people tend to forget is that human evolution is a triangle with biological evolution at one corner, technological evolution in another, and cultural evolution in the third. They are all tied into, and reliant on each other.
If we didn't have our technology (even basic stone tools, clothes and fire) we would be long extinct. Without our thumbs, bipedalism and our big brains we would have no technology. Without our culture (e.g. war, trade etc) our technology wouldn't change, and our technology helps our culture to change too (iPods, iPhones etc). Our biological evolution (big brains, language, reproduction) is the basis for our culture. And our culture also influences our biological evolution, do we let disabled people live and reproduce and keep undesirable alleles within the population or do we let nature select them out of the gene pool? And now our technology is influencing our biological evolution via IVF and genetic screening and maybe one day via direct genetic modification.
