Darwin’s theory of natural selections has been used to explain the biology of animals as well as humans. This theory goes along with the statement survival of the fittest. In some ways it’s a type of mechanism that resembles artificial selection. Through a degree some behaviors or qualities become frequent within a population through a number of generations and other sets of traits start disappearing. These units that happened to be transforming are the genes. The difference between natural selection and artificial selection is the fact that contrary of humans regulating which qualities become prominent, natural surroundings selects it. Just regular natural occurrences will choose specimens are capable of adapting, surviving and reproduce within their regions. As time passes by this usually eliminates specimens that can’t subsist and in turn creates species that can.
For the process of natural selection to work there needs to be three sufficient conditions occurring. These three components include inheritance, variation, and the different rates of survival and reproduction.
When thinking about inheritance, we’re recognizing particular traits that were passed down from a parent. Inheritance can be shown in all kinds of species, including Homo sapiens. A couple traits are hereditary,

This can be shown in the amount of offspring that a species is producing. If the number of offspring being produced is increasing each year then we could deduct that there’s a good number of resources. While if the number is decreasing or simply set then there may not be a large amount of resources in the area. As new generations start emerging they will have gone through or will go through a substantial mortality. Individuals retaining qualities well matched for the strain for limited resources will subsidize the number offspring that will be produced for the incoming
