[email protected] " This definition includes microevolution (changes in allele frequency of a population over time) and macroevolution (the descent of different species from a shared common ancestor over many generations). Humans choose options by deciding what they like best; the natural world also selects options (but not by “thinking” about them) when the environment acts on genetic diversity. Individuals of a population differ from each other and these variations are pre-requisite for evolution by natural selection. After this introduction of natural selection, Darwin elaborated on the subject with his theory of evolution and his book, On the Origin of Species, published in 1859.

On the one hand, all living organisms attempt to perpetuate their kind by producing many more offspring than are necessary to maintain their numbers. Natural selection can only occur if there is variation among members of the same species. Artificial Selection was used as an analogy for natural selection: If humans can breed. lab safety and equipment. In the Natural Selection unit we will look at the theory of evolution by means of natural selection as proposed by Charles Darwin and Alfred Walls. Offspring keep these genes and the same characteristics for the whole of their life but some individuals are better adapted, and reproduce more successfully. Natural selection DOES require heritable variation to occur. Variations in Beaks of Galapagos Islands Finches Name Period __ Date _ 10. High School — AP/IB.

Natural selection is a theory that states that those individuals who are best adapted to live in an area will survive and reproduce. Last updated 8/26/2016. Note that every student must collect all data for each predator and prey type. Natural selection is the only mechanism of adaptive evolution; it is defined as reproductive success of classes of genetic variants in the gene pool. Darwin's Theory of Natural Selection, the pathway of random variations being selected for by environmental pressures such as competition and predation, is the mechanism which modern evolution is.
