Which part of these statements isn't right ? A species is a group of organisms that can potentially interbreed with one another to produce viable, fertile offspring. Speciation is when two new species form from one original one. Sympatric speciation occurs when there is a geographic separation of a population. Allopatric speciation occurs while the population remains in the same area. Adaptive radiation occurs when one species evolves into many to fill several different niches. Natural selection requires traits to be passed from parent to offspring, more offspring are produced than can survive creating competition, and inherited traits vary among offspring. Fossils, Anatomy and embryology, biogeography, and molecular biology all provide support for the theory of evolution. Evolution can be driven by many different things. Mutations are changes in DNA that create new alleles in a population. Gene flow is the flow of alleles in and out of a population resulting from the migration of individuals or gametes. Genetic drift is change in allele frequency caused by sexual selection. The bottleneck effect occurs when a large portion of the population suddenly dies. The founder effect is when a small subset of the population starts a new colony. Divergent evolution is when two species evolve in different directions from a common point. Analogous evolution is when similar structures arise through evolution independently in different species. Homologous structures are structures that share similarities due to having a common ancestor. Convergent structures are similar in function and appearance, but do not have a common ancestor. Vestigial structures are unused structures without apparent function.
