Proposes that the phenomenon that caused the expansion was a great explosion that took place 14,000 million years ago. Then, matter and light that exist today hadn't appeared yet. All particles that formed the atoms of the Universe have passed a process of transformation: The proofs of this theory are cosmic background radiation and the fact that the hydrogen/helium ratio that exists in the Universe is practically the same as that calculated by the model

The initial expansion of the Universe was of the Inflationary or exponential type, that is, it expanded In an unlimited form in a very short period of time.

Gravity, strong nuclear forces, weak nuclear forces and electromagnetism, were probably united or undifferentiated before the Big Bang, due to the conditions of enormous density andtemperature.

Before reaching the limit of 380 thousand years, the Universe was kind of heated cosmic plasma, conformed exclusively of elemental particles of matter and antimatter

The electric attraction between photons and electrons allowed for the formation of the interactions of the strong nuclear forces
hydrogen atoms. permitted the union of pairs of photons and pairs of neutrons which produced helium

The first stars were born close to one another in large litters, which gave rise to the first galaxies. The Milky Way probably was formed 10 thousand million years ago. A very massive type of stars have a relatively short life and an extremely violent end; they explode and this explosion is called supernova

The Sun is a small second or third generation star. It was born a thousand million years ago, and around it. the planets that we know were formed, as the well as the moons, comets and asteroids.

When one of these stars explodes, it pours its valuable content through the cluster of galaxies, and now the new stars that form from their ashes may also form planets
composed of atoms of diverse elements,
as happened with theplanets of the Solar System

Chemical investigation: exclusive components of living beings had been synthetized in laboratories.​
Biogeochemical cycles were understood, as phenomena such as combustion and respiration; also photosynthesis was discovered.

Subsequently, primitive microorganisms began to create and store proteins and enzymes in their genetic code, which generated the first forms of amino acids in the RNA molecular genome.
After these metabolic processes in primitive organisms, RNA gave way to DNA, which facilitated genome preservation and transmission since the double elise structure of DNA had greater stability compared to RNA, all this resulting in a considerable reduction in Generic damage and mutations that used to occur,

Lamarck, in the 19th century, crated a more recent classification based on the
presence or absence of a spinal column and cranium:

1. Vertebrates (with red blood).

2. Invertebrates (blood of of other colors).

Linnaeus was the one who set the rules in his book Systema Naturae (1735); he
determined that species would be ordered  heriarchical or classification
taxonomic categories; these categories , in decreasing direction, were:

Kingdom

Phylum

Class

Order

Family

Gender

Species

To name all species, Linnaeus created a code of binomial nomenclature, a set of
rules to designate binary names to species:

The first name: genus category.

Second name: species category

In 1895, he wrote a book "The Origin of Species", where he proposes: That the species evolve by natural selection The three aspects of evolution are adaptation, transformation and diversification of species.

Herbert Copeland he separates bacteria from. protists creating just for them the fourth kingdom of cells without erganelles:. Monera kingdom. Robert Whitaker In 1959, formalized the fifth kingdom of life. He called it Fungi.
