The dandelion was long popularly known as the 'pissabed' because of its supposed diuretic properties, and other names in everyday use included 'mare'… - Bill Bryson

Since the dawn of time, several billion human (or humanlike) beings have lived, each contributing a little genetic variability to the total human stock. Out of this vast number, the whole of our understanding of human prehistory is based on the remains, often exceedingly fragmentary, of perhaps five thousand individuals. You could fit it all into the back of a pickup truck if you didn't mind how much you jumbled everything up, Ian Tattersall, the bearded and friendly curator of anthropology at the American Museum of Natural History in New York, replied when I asked him the size of the total world archive of hominid and early human bones.
The shortage wouldn't be so bad if the bones were distributed evenly through time and space, but of course they are not. They appear randomly, often in the most tantalizing fashion. Homo erectus walked the Earth for well over a million years and inhabited territory from the Atlantic edge of Europe to the Pacific side of China, yet if you brought back to life every Homo erectus individual whose existence we can vouch for, they wouldn't fill a school bus. Homo habilis consists of even less: just two partial skeletons and a number of isolated limb bones. Something as short-lived as our own civilization would almost certainly not be known from the fossil record at all.
In Europe, Tattersall offers by way of illustration, you've got hominid skulls in Georgia dated to about 1.7 million years ago, but then you have a gap of almost a million years before the next remains turn up in Spain, right on the other side of the continent, and then you've got another 300,000-year gap before you get a Homo heidelbergensis in Germany and none of them looks terribly much like any of the others. He smiled. It's from these kinds of fragmentary pieces that you're trying to work out the histories of entire species. It's quite a tall order. We really have very little idea of the relationships between many ancient species which led to us and which were evolut

I was especially riveted by an amateur photograph in Herrero’s book, taken late at night by a camper with a flash at a campground out West. The photograph caught four black bears as they puzzled over a suspended food bag. The bears were clearly startled but not remotely alarmed by the flash. It was not the size or demeanor of the bears that troubled me — they looked almost comically unagressive, like four guys who had gotten a Frisbee caught up a tree — but their numbers. Up to that moment it had not occurred to me that bears might prowl in parties. What on earth would I do if four bears came into my camp? Why, I would die, of course. Literally shit myself lifeless. I would blow my sphincter out my backside like one of those unrolling paper streamers you get at children’s parties — I daresay it would even give a merry toot — and bleed to a messy death in my sleeping bag.

It was impossible to determine what he was saying, but I imagined he was telling all those present that they were nongs and maggots. I decided I quite liked watching the news with the sound off.
