HARDY – WEINBERG PRINCIPLE:
Operation of natural selection on different trait:
Evolution means changes that occur in population over a time. Modern theory of evolution of man proposes that humans and apes derive from ape like ancestor that lived on earth few million years ago.
Adaptive radiation is the diversification of an ancestral group of organisms into a variety of related forms specialized to fit different environment. Darwin's finches and australian marsupial are its example.
Biological evolution is defined as the genetic change in a population that is inherited over several generations.
Following are the evidences of evolution which includes paleontological evidence, biochemical evidence, anatomical and morphological evidence. Homologous structure are the result of convergent evolution and analogous structure are the result of divergent evolution.
Life was originated about 20 billion years ago. Big bang theory explain the origin of universe. Louis pasteur performed an experiment to explain the origin of life, he daid that life arise
