La foi scientiste : "It is thought we spilt from a common ancestor with chimps 5-6 million years ago, more than enough time for substantial genetic differences to develop." Les faits génétiques : "Unlike our close genetic relatives - chimps - all humans have virtually identical DNA. In fact, one group of chimps can have more genetic diversity than all of the six billion humans alive today." La solution miraculeuse : "The absence of those differences suggests to some researchers that the human gene pool was reduced to a small size in the recent past, thereby wiping out genetic variation between current populations. (...) The small genetic diversity of modern humans indicates that at some stage during the last 100,000 years, the human population dwindled to a very low level. It was out of this small population, with its consequent limited genetic diversity, that today's humans descended. Estimates of how small the human population became vary but 2,000 is the figure suggested in the latest research." BBC Science/Nature |
