Charles Darwin proposed that evolution is the change in the characteristics of a species over several generations which could happen over aeons or within a few centuries. This process of evolution relies on the process of natural selection. Charles’s theory of evolution is based on the idea that all species gradually change over time. The complex process of evolution relies on there being a genetic variation in a population that affects the physical characteristics of an organism. Some of these characteristics may give the individual an advantage over other members of the same species which they can then pass on to their offspring. This process of continuously adopting advantageous characteristics by subsequent generations is called natural selection.

Biological evolution is the study of life how it starts and goes on. On earth, around 8 million living spices and the number of spices increased day by day. Humanities didn’t only look out of nowhere. They are products of the development of billions of ages.

THEORIES OF EVOLUTION
This concept of development by the biological selection, the first development in Darwin’s novel “ on the descent of species” in 1859., is that procedure by which organisms move at the time as a result of changes in heritable physical or behavioural traits. Modifications that allow the organism to better adapt to its surroundings can help it survive and get more consequences.
Beagle concluded that all existing living forms share similarities among themselves and also with other life forms, which existed millions of years ago of which many are extinct.
The evolution of life forms has been gradual and life forms better fit in environments that leave more progeny. This is called natural selection and is a mechanism of evolution.
Alfred Wallace working in the Malay Archipelago also came to the same conclusion.
EVIDENCE OF EVOLUTION
Evidence of the general origin of living organisms has been found by scientists exploring in a variety of fields over some decades, proving that all living on earth gets from a single ancestor. That makes an important part of the information on which evolutionary theory remains, proves that development does occur, and illustrates the processes that created worlds diversity. It supports the contemporary evolutionary synthesis of the new technological concept that explains how and why living changes over time. Comparative anatomy and morphology – It shows evidence of the similarities and differences between living forms of today and that of prehistoric times.
ADAPTIVE MELANISM
Charles Darwin suggested that evolution is the difference in the characteristics of one species over a different generation which would occur at aeons or within some centuries. The knowledge of development relies on the knowledge of natural selection. Charles’s concept of development is from this idea that all species gradually move over time. This complicated process of evolution relies on there being a genetic variation in the population which involves the physical feature of the evolution of the organism. Some of these features may make this individual an advantage over different members of the similar species which they may then give on to their progeny.
ADAPTIVE RADIATION
During his exploration of the Galapagos Islands, Darwin noticed that there were many varieties of finches on the same island.
They varied from normal seed-eating varieties to those that ate
insects.
This process of evolution starting from a single point and radiating in different directions is called adaptive radiation. The other example for this is the evolution of the Australian marsupials from a single ancestor. Placental mammals also exhibit similarities to their corresponding marsupial. Example: placental wolf and the Tasmanian wolf When more than one adaptive radiation occurs in an isolated geographical area, the phenomenon is called convergent evolution.
MECHANISM OF EVOLUTION
Darwin did not quite explain how evolution gave rise to different species of the same organism. Mendel mentioned inheritable factors, which influenced the phenotype of an organism. Hugo de Vries based on his work on evening primrose suggested that variations occurred due to mutations. Mutations are random and directionless while the variations that Darwin talked about were small and directional. Hugo de Vries gave the name saltation (single-step large mutation) to the mutations which brought about speciation.
