But the Reed Sea, north of the Red Sea, was, Roy! Easily.Digit wrote:True, but again you would need to explain how a non-boating/rafting etc group got OOA in the first place. And please don't tell me about sea levels as the Red sea is well over your 400 ft deep mark with no evidence to suggest it was ever that shallow.
There were probably many, many more OOA crossings than just those two, Roy.Digit wrote:I expected that, BUT, according to the archeological evidence there were two crossings. One in the north of the continent, over the Nile, and the other across the lower reaches of the Red Sea.
So apparently we don't we eat large quantities of sugars...Digit wrote: The argumant ran that cooking results in less time and energy being required by our bodies to break down meat and the large increase in sugars powered a large brain and thus intelligence.

Pretty much says it all, and loudly, except for the details. (Note Bene - This particular population was devastated by a massive impact nearby.)Ishtar wrote:Well, we have Malaysian handaxes dated to 1.8 million years old. So if you subscribe to the view that every single type of hominid came out of Africa at some point, which we know the Club does, you could be looking at pegging the beginning of hominid sailing to 2 million years ago.Rokcet Scientist wrote: So for now I peg the beginning of hominid (HE) boating/sailing at around 1 mya.

All of this is another reason why "Man and Impact in the Americas" is a landmark book, which will probably end up in the same class as Gibson's "Decline and Fall", but short of Darwin's "Origins". A great collectable, and a great gift.
