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
