Question and answer
Q: What are two examples of evidence that support the theory of evolution by natural selection? One example should relate to the anatomy or physiology of animals. Locate a website (cite your sources)
that discusses the evolution of a new species. Do you agree this is a new species, or is it diversity within the same species? Explain your answer.
A: As Charles Darwin described it, evolution is "decent with modification." There are a number of evidences both in support and in opposition toward the theory of evolution. [ Some of the most popular evidences in support of Evolution are as follows: Natural Selection and Mutations - Charles Darwin is the most famous scientist in regards to the theory of evolution and natural selection. In
November of 1859, he published his famed book The Origin of Species, which is often considered the foundation of evolutionary biology. In this, he discussed how populations evolve over long periods of time through natural selection, the belief that those animals with the stronger, more beneficial traits in a species outlive those with the less beneficial traits, thereby changing the overall traits of the species. Another trait, usually incorporated within natural selection, is the idea of spontaneous mutations within the genetic thread that cause random changes in a species that are sometimes beneficial to its survival. Speciation & Macroevolution- Speciation is the process by which new biological species arise. This could be allopatric (when a species is split among two geological places), peripatric (small, isolated areas which prevent the species from exchanging genes with the main population), parapatric (the zones of two diverging populations are separate but do overlap), or sympatric (species diverge while inhabiting the same place). Macroevolution is the study of evolution that observes not what occurs in one species, but the changing of the state of the world as a whole. The fossil record- The fossil record is a huge asset to those attempting to prove the evolutionary theory, as the fossil record provides visible, tangible evidence or the morphology of a species over time. Strong connections between current species- Most notably, the linkage existing between apes and humans. ]
