300 millones de años 2/2: El planeta humano

Somos Documental

En los siguientes 65 millones de años, los mamíferos son parte de la historia de Europa. Los mamíferos marinos conquistaron los océanos mientras que las manadas de herbívoros atravesaban la tierra. Hace 600.000 años que el Homo Heidelbergensis empezó a cazar.

00:00This is a journey through an extraordinary continent.

00:08A journey through space and time.

00:12In our journey, we will discover the traces of the ancient oceans

00:16and we will unearth the remains of tropical forests at the summits of the mountains.

00:21The dinosaurs will be our travel companions.

00:28We will meet the Neanderthals

00:30and we will witness a cosmic accident that was about to destroy everything.

00:36We will meet the hunters and their prey.

00:41We will meet the dinosaurs.

00:45We will meet the dinosaurs.

00:47We will meet the hunters and their prey.

00:51And we will accompany Europe on its long journey around the planet.

01:03300 million years.

01:06Part II. The Human Planet.

01:10Welcome to the flood plain of the Rhine River in the Leocene.

01:1510 million years after the impact of a comet devastated our planet

01:20and Europe migrated further north.

01:26In the subtropical climates, mammals had become the owners of the earth.

01:31Here, where the Riesling grape will grow later,

01:35we now find an exuberant and primordial tropical forest.

01:43Half of the mammal groups that exist in our world were already present here.

01:57Also birds, fish and insects.

02:00All the animal kingdom was practically the same as our current world.

02:06Not in Europe, however.

02:09Currently, many of the inhabitants of the Leocene live in the tropical regions of South America and Asia.

02:16Only thanks to a volcano do we know exactly what animals lived here then.

02:2248 million years ago, when the volcano erupted,

02:26a lake 300 meters deep formed in the crater.

02:52Plants and animals disappeared in the depths,

02:55but remained intact on the bituminous platforms.

03:04The Messel Fossil Settlement is very close to the German city of Darmstadt.

03:10Here, strata by strata, the instantaneous excavation of a crucial event in geological history is carried out.

03:16The fossil record tells us about life and death in the crater lake.

03:22It is most likely that the toxic gases emanating from the depths reached the surface of the water,

03:27causing the asphyxiation of the animals, who fell into the lake and drowned.

03:33Many fossilized bats have been found.

03:36They must have gotten too close to the surface of the water.

03:40Presently, the Messel Fossil Settlement is a UNESCO World Heritage Site

03:44and an exceptional window into prehistoric Europe.

03:49It was here that the hand of an ancient primate was found.

03:54The fossils found in Messel are amazing,

03:57true impressions of the animals.

04:00Descriptions of their skin, as well as their fur and plumage.

04:04Sometimes even the contents of their stomachs were preserved.

04:10The most spectacular find to date dates from the 1980s.

04:15An animal similar to a monkey, 60 centimeters long, with a very long tail.

04:35Probably that creature was also a victim of the toxic gases,

04:39like the rest of the animals discovered in the settlement.

05:0447 million years later, the little primate lady caused a great uproar.

05:08Baptized as Ida, for a long time she was considered the progenitor of the human race.

05:12Although there were never any records of her,

05:15it is known that she was the first female primate in the world,

05:19and that she was the first female primate in the world.

05:24She was the first female primate in the world,

05:28and she was the first female primate in the world.

05:32Although there was never definitive evidence of this,

05:36her body exhibits one of the greatest innovations of evolution.

05:40Five fingers with opposite thumbs, a hand with precision grip.

05:47The tropical forest of the Eocene would also be finally buried under the layers of time.

06:03Now, every time we scratch the surface, we can fleetingly glimpse the prehistory.

06:09Here, where the excavators take out the last lignite from the subsurface,

06:14ancient virgin forests grew next to the sea.

06:21Tormenting under the lignite are tons of amber,

06:25and inside, frozen in time, the life of the primordial forests.

06:33Tormenting under the lignite are tons of amber,

06:37and inside, frozen in time, the life of the primordial forests.

06:42Tormenting under the lignite are tons of amber,

06:46and inside, frozen in time, the life of the primordial forests.

06:51Tormenting under the lignite are tons of amber,

06:55and inside, frozen in time, the life of the primordial forests.

07:03The Ice Age

07:07Much of Western Europe was covered by a recent layer of ice.

07:12The glaciers that descended from Scandinavia opened their way to London,

07:17and from the Alps reached Lake Chim in Bavaria.

07:23The glaciers formed and displaced land and rocks,

07:27and left so much water that vast areas of the North Sea were barren.

07:34The Quaternary, the most recent geological period, was a turbulent time.

07:41Many glaciers melted,

07:43and the water from the ice carved deep ravines on the surface of the earth.

07:50As the ice retreated to the north,

07:53the animals of the cold periods disappeared.

07:57The forests reappeared.

08:00Hippos, elephants and rhinos migrated from the south to those regions, green again.

08:07Deer and elephants were neighbors in the affluents of the primitive Rhine.

08:38Now the elephants lived where the mammoths used to graze,

08:42and the deer and wild boars appeared to occupy the place of the rhinos.

08:48The animals migrated depending on the changes in the climate.

08:54But something crucial had changed.

08:57The animals were no longer alone.
