Wet spells in the Sahara may have opened the door for early human migration. According to new evidence, water-dependent trees and shrubs grew there between 120,000 and 45,000 years ago. This suggests that changes in the weather helped early humans cross the desert on their way out of Africa...
While about 40 per cent of hydrocarbons in today's dust come from water-dependent plants, this rose to 60 per cent, first between 120,000 and 110,000 ago and again from 50,000 to 45,000 years ago. So the region seemed to be in the grip of unusually wet spells at the time.
That may have been enough to allow sub-Saharan Stone Age Homo sapiens to migrate north: the first fossils of modern humans outside Africa date from 93,000 year ago in Israel. And both genetic analysis and archaeology show that humans didn't spread extensively beyond Africa until 50,000 years ago, suggesting a second migration at the time of the second wet spell.

They moved to Detroit.
That is sooooo funny!!!
Only if your not from Detroit. :-(
I been through the desert on a horse with no name. It felt good to be out of the rain... ;)

I'm sure some nice photographer person gave them a nice home.

“Ventura Highway” is the only tune of theirs I’ll ever listen to by choice. I’ve heard wind ornaments on people’s porches that have more interesting singing voices. :’)
I used to work with an old WWII veteran; one day we were having a rare conversation and somehow got on the topic (or at least, he did) of his service (formerly I’m not sure I’d known about it). He served in North Africa, perhaps under Patton? Anyway, he said they got on a train in Morocco or somewhere, and chugged across the desert to the staging area. The trip took literally three weeks, nothing to see, little to do. :’)
Nice!
Some of those stone-age humans were triple the size of cattle, impressive!
I remember an article (I think it was a different one) about those. Pretty amazing. Must be some plentiful food supply, perhaps arriving by air? Prolific fish population? Cannibal crocs? :’)
Costco has the NG DVD full collection (1888-to present, not sure if that means end of 2008 or what) available for $40. :’)
Pretty big bucket there. I assume they are talking about algae too? Are they including the sheath bacteria that live on the plants? The latter are important (particularly Pseudomonas syringae), as the surfactants they exude may play a key role in nucleating raindrops on the way to the Amazon.
We have a lot to learn when it comes to driving this bus.
Much the same could be said of most parts of the Middle East deserts. Not much to see or do in those deserts. I would say the American Southwest has more interesting deserts.
Thanks CO.
Except for the length of time spent crossing it. :’)
Nice!
they were headed for the Taylor Swift concert in Libya
cattle were a lot smaller back then...seriously
Oh, my! Did they leave carbon footprints? (sarc/off)
