Outline the processes of maturation and explain how either theory of mind or altruism is an adaptation resulting from the selective forces that have operated dur - stress ExampleThis is also the rationale behind the arrival of variations in the species of organisms through time. The genius of evolution lies in the fact that although organisms have obviously veerd though time, a lot of their features remain strikingly comparable to something from a different age. (The University of California Museum of Paleontology, Berkeley, and the Regents of the University of California, 2008)Simply put, evolution is one of the major factors that cause different life forms to traverse to exist in the universe. Evolution is a complex process that makes use of several mechanisms or sub-processes. These evolutionary mechanisms are responsible for affecting change in population.. (The University of California Museum of Paleontology, Berkeley, and the Regents of the University of California, 2008)Th e basic mechanisms of evolution that affect change include natural selection, genetic drift, migration or gene flow and mutation. (The University of California Museum of Paleontology, Berkeley, and the Regents of the University of California, 2008)Natural selection is the cut of action by which inherited characteristics that are pertinent to continued existence and reproduction become more spectacular. In natural selection, the traits that are detrimental to ones survival become less prominent in the next generations. (DOBZHANSKY, 1955)According to the Understanding Evolution website, genetic drift john be manifestly draw offd as an evolutionary equivalent of a sampling error. Another way to describe genetic drift is that the genetic material from one generation does not go on in the same proportions in the next generations for due to a lot of indiscriminate reasons. Genetic drift can be likened to a lottery where a winner is determined by sheer luck or in this case, chance. G enetic drift affects the process of evolution in three ways. First, genetic drift causes a reduction in variations. This causes a population to be
