More proof for my theory that humans evolved out of piles of poop. From Yahoo:
While excavating in Gladysvale Cave, near Johannesburg, South Africa, a team of researchers from the University of the Witwatersrand discovered an ancient brown-hyena latrine. Upon inspection, hyena coprolites - fossilized dung - appeared to contain uncannily hair-like structures.
Lucinda Backwell, a paleontologist in the group, took a sediment block containing several coprolites back to the lab for a closer look. She and a colleague carefully removed forty of the "hairs apparent" from one of the coprolites and subjected half to scanning-electron microscopy. Sure enough, fossilized hairs they were, and five showed remarkably preserved surface scales.
Comparing the scales to those of a variety of animals - an admittedly tricky undertaking - Backwell's team concluded that human hairs were the best match.
Dating of the cave's limestone layers showed that the dung had been deposited sometime between 257,000 and 195,000 years ago. During that period, both early Homo sapiens and a relation, H. heidelbergensis, roamed the South African landscape.
