Changes in the environment can affect the behavioral and physiological aspects of living organisms. An important concept further supporting this phenomenon is heterogeneity. Unevenness is explained as evolution of individual development, and individual development is the development of individuals from the earliest stage to the mature stage. Evolution takes hundreds of years or millions of years. By studying the earliest notochord, we can combine the emergence of change and adaptation to maintain the life of today's primates.
Evolution affects all aspects of life in living things. Morphology (form and structure), physiology (function), behavior and ecology (interaction with the environment). The basis for these changes is the change in genetic material. Thus, in terms of genetics, evolution involves a change in the composition of biological genetics. Evolution can be seen as a two-step process. First, genetic variation is caused by mutation, secondly, selection occurs, the frequency of useful changes increases, and those that are less useful or harmful are eliminated in the generation. "Useful" and "harmful" are the terms Darwin used in the definition of natural selection. The important point is that those with useful changes are "most likely to survive and breed" (Darwin, 1859b, p. 81). As a result, changes in utility will increase over the frequency of generations, at the expense of something less useful or harmful.
Behavior, physiological and structural adjustment or change of organisms to become more suitable for the environment. According to Charles Darwin 's natural selection evolution theory, the creatures with genetic traits survive and proliferate, and can transfer more genes to the next generation. Deoxyribonucleic acid. Large biomolecule consisting of subunits called long stranded and serially connected nucleotides. The sequence of these nucleotides contains information necessary for cell proliferation, division into daughter cells, and production of new proteins. Changes in DNA lead to mutations, which may be beneficial to the organism, neutral or harmful. When these changes occur in DNA of sperm and egg cells, they are inherited to the next generation.
