1953 extended the study of evolution to most fundamental level the sequence of the chemical basis in DNA both specifies the order of amino acids in proteins and determines which proteins are source of both change and continuity in evolution. The modification of DNA through occasional changes or rearrangements in the base sequences underlies the emergence of new traits, and thus of new species, in evolution. At the same time, all organisms use the same molecular codes to translate DNA base sequences into Protein amino acid sequences. This uniformity in genetic code is power evidence for the interrelatedness of living things.” (Teaching About Evolution and the Nature of Science, ch. 2, pp. 4)

Another powerful argument that supports common ancestry is a fact that man is developed from an ovule, about the 125th of an inch in diameter, which does not differ from the ovules of other animals. At a very early period, the embryo can hardly be distinguished from another member of vertebrate kind.

In order to convince one that evolution happened the way evolutionary theory describes it evidences must be presented. Major evidence and argument of evolutionary theory is that all of the mechanisms of evolutionary theory change are currently observable. Let us take for example main mechanism of evolutionary change—natural selection. Nowadays our society is facing serious public health problem. Bacteria that medicine used to successfully fight with antibiotics is becoming more resistant to one. This means that week bacteria go extinct and only strong (more resistant to antibiotics) bacteria survived. (Teaching about evolution, ch. 2, pp. 5) “continued use and overuse of antibiotics has had the effect of selecting for resistant population because the antibiotics give these strains and advantage over non-resistant strains”
