“The Evolution of Airplanes” Introduction This year is the 200th birthday of Charles Darwin (1809-1882)‚ the father of evolution. Darwin’s evolution theory proposes that all species of organisms‚ including human beings‚ evolved from common ancestors. There are five main characteristics in his evolution theory. First‚ there are variations among each population. Second‚ organisms compete for limited resources to exist. Third‚ traits of offspring are inherited from their parents. Forth‚ organisms

Ever wonder how evolution comes to be? How some species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes

Essay on Evolution There are many mechanisms that lead to evolutionary change. One of the most important mechanism in evolution is natural selection which is the differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Natural selection occurs when a environment makes a individual adapt to that certain environment by variations that arise by mutation and genetic recombination. Also it favors certain traits in a individual
