    1st hominids: 23:53

    1st hominids: 23:53
    They are primates adapted to terrestrial life, to walk upright in a bipedal posture, with the skull also vertical. The feet are not prehensile unlike the rest of the primates, since the first toe is more robust and is aligned with the remaining four. The hands have a developed thumb and are better able to manipulate objects.

    1st angiosperms: 23:22
    Angiosperms commonly called flowering plants or flowering plants are seed plants whose flowers have ordered whorls or spirals of sepals, petals, stamens and carpels; the carpels enclose the ovules and receive the pollen on their stigmatic surface instead of receiving it directly in the ovule like gymnosperms, and when the fruit ripens its "packaged seeds" are found, that is, the mature seed is enclosed in the fruit. , distinctive character that gives the name to the group.

    Age of the birds: 23:39
    Birds display attributes that differentiate them from other vertebrates. Apart from the traits that enable them to fly, their metabolism allows them to grow very quickly and their large brain endows them with keen intelligence and senses. They are so different that their origins have long awakened the curiosity of naturalists.

    Amphibian age: 22:13

    Amphibian age: 22:13
    Amphibians form the most primitive class of vertebrates that, on an evolutionary scale, have managed to colonize the terrestrial environment, thanks to their crosopterygian ancestors who inherited the lung structure, bony limbs, and also provided them with the means of locomotion and the means of breathing air.

    First terrestrial plants (gymnosperms): 21:48

    First terrestrial plants (gymnosperms): 21:48
    Vascular plants and pteridophytes (or ferns) develop, especially abundant during the Carboniferous. 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). Many bryophytes have become extinct, but the current ones inhabit humid forests, and near rivers and lakes.

    Age of the fish: 21:37

    Age of the fish: 21:37
    The first vertebrates on Earth were fish, and scientists believe they first appeared about 480 million years ago. But the fossil records are patchy and only small fragments have been identified. Some 60 million years later, 420 million years ago, the fossil record shows something completely different: a wide variety of fish species en masse.

    Great explosion of life: 9:10
    Practically all major animal phyla started appearing in the fossil record. It lasted for about 13 – 25 million years and resulted in the divergence of most modern metazoan phyla. The event was accompanied by major diversifications in other groups of organisms as well.
