Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation‚ including species‚ individual organisms and molecules such as DNAand proteins.[1]All life on earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological

Evolution is change over a long period of time. An organism’s characteristics change over time due to its DNA. The DNA determines how an organism looks. The process of evolution is over millions of years. Scientists use fossils‚ embryology‚ comparative anatomy‚ and the biochemistry to get data fro the organisms of their evolutionary histories. For this purpose for doing this lab is to related organisms’ skull evolved or change over time. Fossils are past living remain organism that left behind and

Climate Effects on Human Evolution This article explores the hypothesis that key human adaptations evolved in response to environmental instability. This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. (Illustrations for this article coming soon.)
