came across this very slick and well done bit of webery called becoming human. they describe it as follows: an interactive documantary experience that tells the story of our origins. journey through four million years of human evolution..” etc, etc. sections include evidence, anatomy, lineages, and culture. there is a lot of interesting content including many images, lots to read, 4 short films and a host of audio. not sure if you will learn anything new but it’s well done and a fine way to kill some time you’d otherwise waste in a manner containing absolutely no references to cave painting.
