The process of biological change by which descendants differ from their ancestors is known as evolution. This change occurs over generations through mechanisms like natural selection, genetic drift, and mutations. These processes lead to variations in traits, which can affect an organism's survival and reproduction. Ultimately, evolution explains the diversity of life on Earth and how species adapt to their environments over time.

It is called "evolution".
Evolution
Biological evolution is the change of animal and plant life over time. Biological evolution is used to explain changes in finch beaks for example.

A biological process imply chemical and physical changes.
The central claims of evolutionary theory are these:That traits are inherited.That lifeforms reproduce with variation in their inherited traits, causing the descendants to be modified versions of the ancestor.That variant descendants compete with one another for resources and mating opportunities.That the ability of variants to compete affects the average number of offspring they may produce.That the above mechanisms can cause and has causeddiverging lineages to come into existence - that modern lifeforms are the product of divergencing lineages stemming from common ancestors.
Biological evolution is defined as the process in which the genetic characteristics of a population change over time through successive generations.
