When the Sahara Was Green

[@markcloutier873]

I worked in the Libyan desert in 1980. There, about 280km south of the gulf of Sirte near Zilah we saw a larger area of hundreds of petrified trees. Many sections were a few feet in diameter and several feet long and tree rings were perfectly preserved. The petrified wood was a shiny black rock, very heavy.

The rock artist were really artists. The detail and dedication it took to carve those drawings into solid rock is astounding and awe-inspiring. One question though; one picture is of a human and a giraffe but it looks as though the giraffe is eating from the human's hand. Would it be possible to train a giraffe to do that? I mean not in a zoo or place where the giraffe had access to its normal diet and didn't need to depend on humans for food. In any case the scene is so peaceful and gentle it almost makes tears.

[@SuedeBoy69]

What if humans were actually a lot taller than we are now. But back then it was normal, so they didn't make a big deal about it and feeding a giraffe out of our hands meant we didn't have to reach very high, and the giraffe didn't have to bow very low. Imagine!

Or simply as a meat animal, that long neck is all muscle, the rest of it is just a bigger version of horsemeat and because it grazes on trees it won't compete for the lower grasses that goats and oxen would eat.

Interesting video to say the least.

This further goes to show the significance of climate change on human history; A Sahara that stayed green would have meant stronger links for trade, dissemination of ideas and civilization building. The Sahara is also half a continent of land not arable and going to waste, imagine the scale of arable land available in a green Sahara with large lakes!

I think your right lol. The Sahara desert formed in approximately 300 years, a time span equivalent to the duration between the present day and the signing of the Declaration of Independence. I assume that people likely flocked in areas abundant with resources and engaged in rapid trade. This likely also triggered the agricultural revolution, as the scarcity of fresh fruits and vegetables in the desert would have made them increasingly difficult to get. This may have also provoked the beginning of conflicts among mankind to assert dominance over land.

I'm sure its possible given enough time and luck, but generally speaking Olmecs and Aztecs aside, civalisations appear to be more probable when groups of people are exposed to harsher conditions, for example the event that gave rise to Egypt itself was a great drought that the first known pharaoh conquered with canals off the Nile, single handedly unifying upper and lower egypt and becoming the first pharaoh of greater egypt.

I have heard that Saharan dust is an important factor in fertilizing the Amazonas Raindforest. Has there been any research into how the Green Sahara impacted (if at all) Amazonas? Also, if the Northern hemisphere got warmer, did the southern hemisphere cool at the same time, or was this an overall increase in solar radiation, and what impact did that have on a global scale?

[@jacobkobald1753]

I was just gonna ask that

[@iamspencerx]

My guess is that earth's tilt would make the southern hemisphere a bit cooler, however, since it doesn't have much landmass in it, it would've cooled down just a little. You should also take into account the global temperatures at that time

[@zddxddyddw]

I believe at that time the Amazon didn't exist as it does today. There wasn't a single, gigantic rainforest. What there was, was a collection of small patches of jungle separated by vast expanses of savannah, a landscape similar to today's Cerrado in Brazil.

[@squirlmy]

I wonder too, if the Green Sahara was so fertile and lush that people didn't need agriculture. When the normal foods of homo sapiens became scarce, they grew to depend on crops from the flooding Nile Valley. (Also needing food supplies to supply an army, and specialized farmers and peasants to grow and cultivate these crops.) Basically, I think what Eddie brevet said could be expanded and explored a lot further.

[@VidarrKerr]

@@squirlmy Agriculture is necessary to make a civilization like that. Without agriculture (and animal husbandry) civilizations cannot become very advanced, because they are all required to "hunt and gather" --almost every person is involved in food acquisition. You have to have food stores (storage of food, production of food greater than the people producing the foods can eat) to free people up to devote time to other tech, like architecture and art and music and everything else people do that does not directly feed themselves.

I've always wondered what would happen if humans were to deliberately create a canal running through much of the Sahara to any part of it that is lower than sea level, to encourage a more permanent water source. The canal would basically never stop flowing toward the lake, because the intense heat would cause the water to perpetually evaporate. This evaporation would create more clouds, and then hopefully cause more rain throughout the desert.

[@angrygopnik2317]

Not worth it financially. You underestimate how massive the Sahara desert is and how unstable and dangerous the governments that own these places are.

[@Toastmaster_5000]

​@@angrygopnik2317 If you look it up, there is a place I think in Egypt's desert that is below sea level, and the distance is short enough that a canal could be built; there have been bigger and more complex projects. And yes, the lake constantly filling up, evaporating, and causing rain is kinda the point of my idea.

Speaking of Africa can you please do a video on African mega fauna like the Natodomeri lion, Palaeoloxodon Recki, Pelorovis Antiquus, Sivatherium Giganteum and the Xenocyon subgenus.

[@biglil771]

Some background information on the Natodomeri lion and Xenocyon subgenus since they're not as known. First off the Natodomeri lion, the Natodomeri lion is a gigantic lion found in Kenyan rocks that date to circa 200,000 years ago. It is thought to have been a new subspecies of lion that grew to larger sizes in order to advantage of larger prey such as Pelorovis Antiquus. The lion would have had a basal skull length of +380mm at least and since the condylobasal skull length is normally 25-35mm longer than the basal an estimation of +410mm can be achieved. Since the greatest skull length is even longer than the condylobasal the greatest skull length would be +460mm at least, rivaling and possibly surpassing the largest cave lions both in America and Europe. The Xenocyon subgenus is a taxonomic group of canids that are found throughout the world. Two of the members, Canis X. Lycanoides and Canis X. Africanus were found in Africa though Canis Lycanoides could be found in Europasia too. C. Lycanoides was a giant canid that rivaled even the dire wolf in size and overall all the members of this group were large. These hypercarnivores are thought to be the ancestors of the African wild dog and the dhole.
