Document Summary
What types of mutations are most likely to fuel evolution as discussed in class: by messing with the genotype, you mess with the phenotype, not everything that changes in your genotype will show up on the phenotype. Speciation: the process by which new species arise: the evolution of reproductive isolation within an ancestral species, resulting in two or more descendant species. Species: a complex concept with carious definitions, a fundamental taxonomic category to which individual specimens are assigned. ***the particular concept ones uses expresses their view of the role of a species in nature or the method used to delineate it as a matter of convenience. ***the pattern of speciation say something about the pattern of natural selection (i. e. more species in the tropics than in temperate. Therefore, does this mean that natural selection acts differently in these two regions?)
