I'm not assuming anything. You could well be right.Why do you assume it is either this route or that one? I bet it was all of them!

Indeed, sea levels were 400 feet lower a number of times in the last couple million years. It went up and down like a yo-yo. So the continental shelf was available for habitat and migration a number of times too.Minimalist wrote:Just because sea level was 400 feet lower at the LGM 17,000 years ago does not mean it was 400 feet lower 1.2 million years ago. There were many fluctuations of the ice.
Kind of like the parting of the Red Sea . . .
The bones are similar to fossils thought to be 800,000 years old found at the same site in 1994, suggesting a continuous human presence in Western Europe.
Up to now archaeologists had found evidence of human activity in Spain, France and Italy around 1 million years ago but no human remains, only animal bones and stone tools.
Hopefully we'll start getting some pics of the stone tools soon. We're beginning to have a new picture of man's European occupation.Flakes of flint embedded in animal bones, suggesting the use of a crude knife, were amongst the finds discovered at the site last June

Not only intent, but compared to myself it demonstrates a lot of skill. I wouldn't know how to go about it.carving a slot in a bone and inserting flint flakes definitely demonstrates intent.
Sorry, Beags -- No such thing. Glaciation began about 2.5 million years ago with the approximate 100,000 year cycle in place.Regarding the climate for our unlabeled man, all I'm finding for sure is that this time period is about 400,000 yrs. before the first major pleistocene glaciation in Europe. So - probably a pretty decent climate.
It's easier with false teeth they tell me!(I can never pronounce that properly)
Maybe I could have explained that better, I'm not sure Cogs. Anyway, as you say, the Ice Age began about 2.5 Mya when the land bridge between the Americas blocked the tropical flow between the two oceans.Cognito wrote:Sorry, Beags -- No such thing.

The most likely culprit for the onset of this epoch is the joining of North and South America at the isthmus (I can never pronounce that properly) sometime after 3 million years ago. Prior to that time water ran from the Pacific Ocean directly into the Atlantic Ocean where the future isthmus was to be located. Concurrently, currents swept part of the North Atlantic westward and then south through the Bering Sea into the Pacific Ocean.
