The succession of organisms through geological times
The apparent age of life is divided into four main periods:
1- Pre-Capricorn from 3200 to 600 million years:
It is the age of life manifested in its first primitive form, where algae, primitive fungi and molluscs appeared in the sea and these microscopic forms merged into algae, shells and oysters. Hence the beginning of life on earth.
2 - Balinese era of 600 - 248 million years:
It is characterized by six ages:
A - Capricorn: characterized by marine invertebrates and also showed some vertebrate fish
B - Udofeni: characterized by primary plants and coral reefs and trees eat meat
C - the evolutionary: and the beginning of the emergence of animals on land like donkeys and spiders
D - Devonian: Amphibian fish with lungs and gills
E - Carboni: the beginning of the emergence of reptiles and the emergence of 200 species of kerosh The dragonfly was a giant and had four wings length of each meter. The frog was in the size of the calf, some had 3 eyes, and the third eye was above the top of the head and was turned to the guard
And - Albarmi: And the number of vertebrates and reptiles and the extinction of most previous neighborhoods
3. Mezuzini era from 248 to 65 million years:
And divided into 3 ages:
A - Tariasi: the emergence of the first dinosaur and mammals and ended this era of extinction for 35% of existing neighborhoods, which enabled the dinosaurs to prevail in the world
B - atmosphere Rasi: (era of dinosaurs) emergence of animals warm blood and some mammals and the beginning of the emergence of reptiles and giant birds by land and sea
C - Cretaceous era: where the extinction of dinosaurs after living on Earth 100 million years. And increased the types and numbers of small mammals primitive and appeared dinosaurs with feathers and crocodiles and witnessed the era of the activity of the displacement of the earth's crust and urban activities. In which the death of dinosaurs occurred 65 million years ago. And eliminated 50% of the species of marine vertebrates.
4. The Cinozo era from 65 million years to the present time.
A - Triple:
1- Pliocene: in which large mammals appeared placenta placenta, primary primates and small horses of size with hooves with three fingers
2 - Eocene: rodents and whales
3 - Eligosini: the emergence of new mammals such as wild pigs and cats and crutches
4 - Miocene: the emergence of mammals such as dogs, bears, monkeys, horses and birds
5 - Belarusian: the emergence of the first primitive man and whales as we have.
B - Quartet:
1 - Pleistocene: It is the Ice Age where vertebrate mammals were extinct and appeared in this era, the human sterile tools and mammoth animals and tigers with teeth that resemble swords
2 - Holocene: the last geological ages and has reached the highest levels of human beings and most of the living things as appeared in this era and even this time on the same form.
