Question

Define evolution? How does it occur to describe how fossils provide us evidence to support evolution?

Answer 1

Charles Darwin was the first scientist to introduce evolution in his book “ON THE ORIGIN OF SPECIES “.
When a species turns itself to adjust the nature and surroundings to live and these adjusted characteristics help organism to sustaining the living which results in change in gene information then it is called genetic variation. These are the core reasons for the evolution which was explained by all the theories of Darwin

Complete answer:
Evolution is a slow or continuous change in gene characters in all the life forms from generations to generations. It is a gradual change observed in all the living species as these characters are being passed from one generation to another generations through the reproduction process.
Evolution occurs in many ways. There are many theories which can help us understand the process of evolution. The first scientist to point to evolution was Charles Darwin. He introduced many theorems and performed many experiments to explain the process of evolution on earth.
From his theorems it is observed that there are factors which support evolution, few of which include natural selection, survival ,genetic variation, genetic drift; all these are the characters which are included in the process of evolution from the historical period to the modern period.
Fossils are the major evidence which can tell us about the life on earth and age of earth they are the crucial remnants which can explain the modern era about the pre Darwin era.
Fossils will help in understanding the earth before man 's existence; the clear evaluation of fossils will give us an idea about the Organism and the age of an Organism or the period of an Organism which can be compared with the present evidence to understand their living possibility.

Note: Evolution is the change taken up by the species in order to survive and this process is slow and continuous it is not just the species.
It can also be seen in the universe according to the big bag theory the universe was formed from a single mass which was seen to be evoluted to form the complete world hence, evolution is the key for scientific study understanding.
Fossils are considered as the evidence for the evolution , e.g., the bones or the skin of fossil remains of dinosaurs can explain the Mesozoic era which is around 66 million years' before dinosaurs once inhabited earth. The study of fossils is called as paleontology
