Miller's experiment proves that organic matter can transform by inorganic matter thanks to the chemical reactions in the Earth in those days. (gases like amoniac, or the atmosphere, the impact of the meteorites...).
Miller represented the Primordial Soup with his experiment. -
Some of the long chains surrounded by a membrane and become protocells.
-
They are colonial microorganisms that live in some waters, for example in Australia. They are the oldest organisms on the Earth.
-
They appeared thanks to the Primordial Soup, because the organc molecules joint.
-
Stromatolytes reproduce ammount of oxygent and then the atmosphere become oxydyzing. This change made the apparition of new forms.
-
As we said new forms appeared with oxygent, one of them were Eukaryotic cells, which obtains the energy burning organic matter with oxygent.
First they all reproduced assexually but then the sexual reproduction arrived. -
Sexual reproduction gave them the capacity of exchanging information and adapting to the changes in the environment. Ans thanks that, the created multicellular cells (cells with especial and concrete functions).
-
Thanks to cell differentiation and sexual reproduction started appearing new unusual species like vertebrates, although, the first specie wasn invertebrate.
-
They became the dominant terrestrial vertebrates their dominance continued through the Jurassic and Cretaceous periods. They are a varied group of animals (birds, fishes…) we know about them thanks to the fossils.
-
They are exiting because of the changes that caused a meteorite that fell on the Earth
-
The first mammals evolved from a population of vertebrates called therapsids (mammal-like reptiles).
But, it was only after the dinosaurs went that mammals were able to evolv forms into the widely specialized species that populate the world today. -
Most animal species flourished and became extinct long before the first monkeys and their prosimian ancestors evolved.
They are mammalian primates that include lemurs, ai-ais, monkeys apes... with humans included in the last category -
It was the first hominid primate (Hominids are a family of primates that includes human beings and fossil species).
-
When discovered, it was considered the oldest species in the genus Homo. His name means "skilled man" and refers to the finding of instruments.
-
A main characteristic of Homo erectus is the shape of the cranial vault.
-
They had a biggest cranial vault, and they started communicating.
-
This is our specie!
