00:00The desert of the Sahara looks like a film of Mad Max,
00:04weather torrid, infinity, and a devastated landscape in general.
00:08A place where no one could live, right?
00:11Well, forget everything you know.
00:14Because it was 5,000 years ago, the Sahara was a luxury paradise of prairies, lakes and rivers,
00:20and a fantasy civilization that disappeared without letting trace.
00:24Our history begins in the 1930s,
00:27when a Hungarian explorer was found in a cave in the middle of the Sahara.
00:30In the interior, he discovered something bizarre.
00:33It's ancient paintings,
00:35representing people living in a lake,
00:37surrounded by giraffes, hippopotames, and crocodiles.
00:41At the time, everyone had their shoulders,
00:43as a symbolical representation of the above.
00:47Because, frankly, who could imagine a lake in the Sahara?
00:51A rapid speed of about 70 years later,
00:53when a group of archaeologists made a discovery which has reversed the situation.
00:57In an abbey sous-roche in Libya,
00:58they put on the floor 15 momies,
01:00as well as the paniers,
01:01the pots in ceramics,
01:02and other objects of everyday life.
01:04It may seem like a prehistoric for most people.
01:07But for the archaeologists,
01:08it was like discovering a key place to conviction.
01:11These people didn't make that happen by there.
01:13They lived here.
01:15You see,
01:16it was not any any momies.
01:17They were part of the most ancient humans
01:20naturally momified,
01:21never discovered,
01:22datant of more than 7000 years.
01:24Ha ha ha.
01:25Prends that.
01:26Egypt.
01:27Two of them had still a ADN lisible,
01:29preserved by a rare process of natural momification,
01:32almost a miracle
01:34due to the capacity of the climate of Sahara
01:36to transform everything in a sea.
01:38The scientists had a bit of trouble
01:41for a certain time to understand
01:43where these momies came from
01:44because the ADN mitochondrial
01:46that they had acquired
01:47was not at all useful.
01:48But thanks to the scientific progress,
01:50they finally managed to do
01:52a complete genome analysis
01:54which revealed an strange secret.
01:56These people belong to a human
01:59that was completely unknown
02:01and they lived isolated
02:02from the rest of humanity
02:04for thousands of years.
02:05During decades,
02:06the researchers said
02:08that the place where they lived,
02:09the Sahara Vert,
02:10was like an autoroute
02:11pre-historical
02:12a luxury
02:13that humans and animals
02:15used to migrate
02:16between the Sub-Saharan and the Mediterranean.
02:18But the momies
02:19have demolished this theory
02:21like a hippopotame
02:22sitting on a chateau of sable.
02:24Their ADN
02:25didn't show any genetic
02:26with the migrants subsaharan
02:28and eurasian
02:29keeping their genes pure
02:30for 7000 years.
02:31Their closest parents
02:33genetic
02:34are not their neighbors
02:35living just below the famous desert.
02:37But some ancient
02:38hunter-cayers
02:39and even
02:40people who live
02:41in the Republic
02:42Tchèque
02:43while they were not
02:44even a country
02:45there,
02:4650.000 years.
02:47We are not yet
02:48out of the house
02:49because these
02:50momies
02:51have also
02:52small traces of ADN
02:53of the Neandertal.
02:54Only 10%
02:55of the quantity
02:56found in the modern era.
02:57If you have
02:58attention to the school,
02:59then you know
03:00that the Neandertalians
03:01lived in Europe
03:02and in Asie
03:03and that the first humans
03:04were not combined with them
03:05after having
03:06migrated out of Africa.
03:07But these people
03:08do Sahara Vert
03:09have never
03:10quittered Africa.
03:11So how did they
03:12have acquired the
03:13Neandertals?
03:14The dominant theory
03:15is that their ancestors
03:16were not
03:18used in Africa
03:19in the North
03:20before
03:21building in the Sahara
03:22and cutting
03:23the contacts
03:24with the exterior world.
03:25The archaeologists
03:26also found
03:27tools in stone
03:28and wood
03:29in an abyss
03:30prouvant
03:31that these people
03:32men a life
03:33florist.
03:34This discovery
03:35has left the scientists
03:36for a certain time
03:37because,
03:38you see,
03:39the domestication
03:40of animals
03:41was not developed
03:42in Africa.
03:43So how did they
03:44have never been
03:45an ancient YouTube
03:47tutorials?
03:48Probably not.
03:49The researchers
03:50think that they
03:51have to exchange
03:52knowledge with
03:53neighbors,
03:54but only
03:55knowledge,
03:56not the salive.
03:57It's almost impossible
03:58to believe that
03:59no other people
04:00who would not
04:01want to live
04:02in a prosperous civilization
04:03in the middle of a
04:04paradise,
04:05eating meat,
04:06and even using
04:07the animal
04:08as a source
04:09of protein.
04:10Miam!
04:11They didn't need
04:12to chase for each
04:13repas,
04:14and the water
04:15abundant
04:16they were really
04:17happy.
04:18And yet,
04:19they never
04:20would never
04:21be able to
04:22get out of
04:23their own
04:24group.
04:25Maybe
04:26the landscape
04:27even kept
04:28isolated.
04:29It's there
04:30that the scientists
04:31believe
04:32that the
04:33river
04:34who existed
04:35in the Sahara
04:36vert
04:37acted like
04:38the
04:39panache
04:40of
04:41the
04:42and the
04:43society
04:44entire
04:45world.
04:46This
04:47isolation
04:48is the reason
04:49for which
04:50their genes
04:51were so unique.
04:52But this
04:53temporal
04:54genetic
04:55has failed
04:56not to survive.
04:57The Sahara
04:58was even more
04:59impitoyable
05:00today,
05:01a real
05:02zone
05:03where humans
05:04could not
05:05survive.

05:29after
05:30the
05:31sea
05:32of
05:33the
05:34sea
05:35of
05:36probably how the Sahara became a vert after all this,
05:39to become a desert.
05:41Well, everything started there 15,000 years.
05:43I was not there at this time,
05:45when the Earth was released from the last air glaciers.
05:48The axis of our planet was a little unstable,
05:51and because of this, the north's hemispheres were approached by the sun,
05:54receiving thus more light and heat.
05:57This eternal year has transformed the North Africa in a gigantic sea of humidity,
06:02attirant the Atlantic and the making pleuvoir on the Sahara.
06:05The result of this incredible amount of pluies was a luxuriante,
06:09dotée of lakes, of the size of a little country.
06:11But the African humid period was not just a punctual miracle.
06:15The truth is that this eternal passage between the Earth and the desert
06:19has occurred more than 230 times in the Sahara since the desert is born.
06:23In one of these events, the Sahara has even been extended,
06:26becoming more large than it is today.
06:29So, when the Sahara Vert has made its appearance,
06:31you can say that it has brought the ultimate transformation of the ecosystem.
06:35It was not just a light layer of sand,
06:37we are talking about a real metamorphosis.
06:40The transformation was so complete that it had even remodelées the populations animals.
06:44The guépards had suddenly had trouble with the new dynamics of the proies,
06:48while the rongeurs, like the multi-mammare,
06:50prospered in the prairies, becoming suddenly abundant.
06:54It was like a Tom and Jerry inverse.
06:56But not even your maillots of bain historical, this paradise had the dents.
07:00The Sahara was an ecological labyrinth of rivers infested crocodiles,
07:05of moustiques porteurs of malaria and of greats félins tapis in the hautes herbes.
07:09The traversal would have been like a real version of hypogluton.
07:13It's probably why more groups of groups were not installed in a permanent way.
07:19The climate of the Sahara has descended between the humid and wet periods and sèches all the 20.000 years.
07:23Difficile to call it a stable code.
07:26For the most ancient peoples, it was more judicious to consider the Sahara Vert as a buffet to want,
07:32to take the resources and leave before the desert return.
07:35However, this period of the Sahara Vert has lasted 10.000 years,
07:39leaving our bergers mysterious a lot of time to prosper.
07:42But it's about 5.000 years, the axis of the earth has changed again,
07:46and the Sahara s'est asséché plus vite qu'une flaque d'eau en juillet.
07:51While the desert was returning, the bergers of the Sahara Verts had no choice that to
07:56rassembler their bétails and to leave.
07:58Some researchers think they have migrated to the Nil,
08:01thus thus the base of the ancient Egypt Egypt.
08:03I suppose so that their heritage perdure.
08:05The more, their line is pure and perhaps teint of our days,
08:09but some gènes tenues of the mummies can still be found in the inhabitants of the Nord today.
08:14But the mummies introverties were not the only ones to use the Sahara Verts as airbnb.
08:19They were in reality just at the corner of the street, in a village at the bord of a lake au Niger,
08:24to be precise.
08:25These people have prospered for 5.000 years and have left behind them the most ancient cimetière
08:30of the Sahara desert, including a man in a carapace of a tortue,
08:35a man of Halloween, souring with the dents limers,
08:38and a family familial poignant figment in the time,
08:40victims of the same eau who supported them.
08:43Finally, these people have also disappeared,
08:45like this happened to our anti-social friends.
08:48This proves that this desert is all the world with a landscape
08:51which offers the paradise of one hand and takes the other hand.
