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,
