1st Homo sapiens: 23:59
The oldest Homo sapiens fossils are almost 200,000 years old and come from southern Ethiopia (the Kibish Formation of the Omo River), considered the cradle of mankind (see Kibish Men). These fossil remains are followed in antiquity by those of Homo sapiens idaltu, with about 160,000 years. -

1st hominids: 23:53
The first hominin in which there is complete consensus is Australopithecus anamensis, which lived 4.2 ma ago in Ethiopia. However, there are other hypothetical hominins that would be older. -

1st angiosperms: 23:22
The first fossils of angiosperms come from the Secondary era, the Lower Cretaceous, so it is inferred that they must have appeared in the Triassic or Jurassic. These are pollen grains similar to those of gymnosperms and the remains of whole leaves and parallelinervias. -

Age of the birds: 23:39
The birds originated from bipedal Jurassic carnivorous dinosaurs, 150-200 million years ago, and are, in fact the only dinosaurs that survived the mass extinction produced at the end of the Mesozoic. -

1st dinosaurs and mammals: 22:44
Los primeros fósiles de dinosaurios confirmados incluyen a los saurisquios Saturnalia, Herrerasaurus , Staurikosaurus, Eoraptor y Alwalkeria .
The first mammals appeared at the end of the Triassic, a little over 200 million years ago, but they remained in the shadow of the dinosaurs until they disappeared during the Cretaceous-Tertiary mass extinction, about 66 million years ago. -

Age of the reptiles: 22:43
The Mesozoic Era is known as "the age of reptiles" because it is the dominant group of vertebrates on land and in the seas. The Mesozoic lasted between 250 and 66 million years ago, and during that time the great reptiles known as dinosaurs had their heyday. -

Amphibian age: 22:13
The most widely accepted theory of the origin of amphibians explains that, between 400 and 350 million years ago, they evolved from freshwater fish with fleshy, lobed fins that looked like legs. -

First terrestrial plants (gymnosperms): 21:48
About 485 million years ago, green algae conquered the earth and became the first land plants, called bryophytes or mosses (plants used to decorate births at Christmas). -

Age of the fish: 21:37
The Devonic is a system and period of the geological temporal scale that belongs to the Paleozoic Age; it is divided into six periods of which the Devonic ranks fourth, following the Siluric and preceding the Carboniferous. -

1st most complex life forms: 9:07
2.1 billion years ago, that is, 1.5 billion years before scientifically proven, complex life forms would have appeared. -

Great explosion of life: 9:10
The Cambrian explosion or Cambrian evolutionary radiation was the sudden appearance (from a geological point of view) and rapid diversification of complex multicellular macroscopic organisms in the early Cambrian period, 542/530 million years ago -

1st life forms: 4:10
Fossils from 3.770 million years ago become the first proof of life on Earth. The finding confirms that life thrived in hydrothermal environments shortly after the planet's formation and will help identify traces of life in the universe. -
