Natural Selection and Patterns of Evolution Worksheet
Complete the worksheet writing 100- to 200-word short answers for each question. Format your references consistent with APA guidelines.
1. What is the direct evidence in support of the theory of natural selection? Include at least four examples. Natural selection means the process in which life forms by having traits that enables them to adapt to their environment. There are many examples of direct evidence in support of the theory of natural selection. (www.Ask.com). A few of those examples includes: Humans, findings of fossil records, record finding of changes in existing species, and biochemical and anatomical similarities.
2. Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms? Why? Yes, humans are subject to the same pressures of natural selection as other organisms we evolve just like other organisms. We are subject to the pressures of evolution. (www.Livescience.com)
3. Provide an example of convergent and divergent evolution, adaptive radiation, and co-evolution. Then, choose one of the examples you provided. What implications might this example have for future humans? Sharks and dolphins are examples of convergent evolution. They both belong to two different vertebrate groups. Sharks belong to the fish group and dolphins belong to the mammals group. Implications of this example might have for future humans may be that convergent evolution are unrelated species living in similar environments and facing different changes.
4. How does a new species evolve from a pre-existing species? Include a brief analysis of the factors affecting speciation. New species evolve from a pre-existing species because of speciation. Speciation can also be referred to as the origin of species. Factors that may affect speciation may be caused from reproductive isolation...
