Adaptation , Species changing to become better fitted to their environment, sympatric Speciation, the formation of new species in the same geographic region, Adaptive radiation , Adaptations allows populations that started off the same to adapt to their environment, vestigal features, inherated structures from ancestors that now have a reduced function, microevolution, change in gene frequency within a population, transitional species, species that is the inbetween between two different species , convergent evolution, distant organisms independently evolve the same trait, biogeographgy, species with the same way of life in the same area are more closely related , founders effect, A new colony started by a few members of the original population, genetic bottleneck, reduced genetic variation due to a significant population reduction in one generation, natural selection, Organisms better adapted to their environment survive and reproduce, divergent evolution, species evolve to be different from a common ancestor, coevolution, species influence each other's evolution, genetic drift, reduce genetic variation due to random events, sexual selection, Individuals competing to reproduce , gene pool, all genes present in a population, Pre-zygotic isolation, temporal, spatial, behavioural, mechanical, gametic, Post-zygotic isolation , Hybrid Breakdown, infertility, inviability , speciation , new population no longer can breed with the old population, homolgous features, similar structures to a common ancestor but with different functions.
