The major theories of biology are; evolution by natural selection, inheritance, cells, biological classification, bioenergetics, homeostasis, and ecosystems. Evolution by Natural Selection has two parts; the first is “species (distinct forms of life) change or evolve over the generations.” The second is “the mechanism for this species change is called natural selection.” Inheritance or otherwise known as characteristics, “of organisms pass from one generation to the next by means of hereditary “factors,” now called genes.” Cells are the smallest component capable of showing every characteristics of life. Biological Classification is the evolutionary relatedness among species. Bioenergetics is transformation of energy in living organisms. Homeostasis is “Organisms tolerate widely varying external conditions by
