The processes of evolution - Essay Exampleterbreeding natural existences, which be reproductively isolated from other groups, (Hausdorf, 2011).In essence a species is considered the biggest gene pool that can occur chthonian natural conditions.Populations connected by gene flow argon often hard to classify. While a species concept defines the conditions under which a population should be classified as a species a population are privates that belong to a specific species and are usually located in an area that is open to be defined. Populations inter portrayal with other populations in their environments and their physical environment also interacting with those populations of another species. Populations that grow exponentially can reach the maximum sustain sufficient of their population in a certain environment.There are four distinguishable forces of evolution natural selection, mutation, gene flow, and genetic drift. Natural selection has four different components which str uggle with each other to change certain traits within populations (University of Michigan, 2010). Natural selection is candid to inheritance, whereas traits are passed on through heredity, variation such as hair color and eye color or other individual characteristics. An increased rate of population growth means that each population is subject to struggle for a dwindling supply of resources. Finally differential survival and reproduction means that those individuals more suited to the struggles will pass on more offspring and genes which are able to withstand different conditions. Natural selection depends on traits that are inheritable.Mutation causes new genetic variations in a certain gene pool. These mutations cause the variation in genetics that allow others evolutionary forces to act such as natural selection, gene flow and genetic drift. Gene flow occurs when individuals move into and out of certain populations. An example of this would be Americans resettling in other Count ries and producing offspring. This affects that
