Fish Swam the Sahara, Bolstering Out of Africa Theory

My objection is to the way studies are presented in the news. I don’t really question the idea that most of our ancestors originated in Africa. Overemphasis of isolated studies does no one any good. You may recall the assertion that dry woodlands prompted bipedal ape evolution while now this seems to have come after bipedal apes roamed the rainforest.

Yeah, Chuck did the same thing to Aragorn’s forest. Really P.O.’d a lot of Ents.

The cradle of humanity lies south of the Sahara, which begs the question as to how our species made its way past it...

DUHHHH!

The easiest way past the Sahara is to follow the banks of the Nile from Lake Victoria!

Now, that’s ENTertainment!

Just a couple of random observations:

1. A mere 2400 years ago or so when Rome and Carthage were squaring off for dominance of the then-known world, much of North Africa was tropical or savanna. Hannibal's famous elephants weren't carted over the Sahara Desert, they were native to the Numadian Empire, roughly what is modern-day Algeria and Morocco.
   
2. All those Roman chariots and charging elephants evidently stirred up so much dust that the tropics turned arid and the savanna turned into the Sahara desert.
   
3. Other scientists believe the African continent once abutted South America, so man could just as easily have walked to modern Brazil as crossed the Sahara (which didn't exist in its present form) or floated down the Nile.

They ate the fish and drank the water. I think the Saharan pluvials are not timed by the Ice Ages in general but rather lag behind the period of greatest glaciation ~ which affects Earth's wobble.

California also has recurring pluvials.

That's OK. Their bark is worse than their bite.
