Out of Africa, again

Amazing news out of East Africa... a new 4.4 million year old hominid species (Ardipithecus) have just been described after 15 years of painstaking research. Old 'Lucy' (Australopithecus) was 'only' 3.3 million years old. Turns out that the common ancestor of chimps and humans, might have looked a lot more like a human than a chimp and not been adapted to tree-climbing, for example. Science is really great... I love it.
