Human variation - Assignment Example e same note, natural selection entails the survival of the best species in terms of survival techniques since nature poses a wide range of challenges in a bid to survive. In addition to that, genetic shift entails the acquiring of survival traits and consequently the passing on the traits to the generations to come. Evidently, this is aimed at enabling the organisms, in other words, humans to survive and reproduce effectively in nature. Finally, there is the issue of chance inheritance which entails the selection of the most suitable survival trait in a bid to pass it on to the next generation. With the shifting and movement of people over the world, it has promoted the spread of traits. Evidently, for instance traits like the ABO are perceived to have originated from one region. However, with the movement of people with the aim of seeking the most appropriate place to settle the trait has been passed all over the world. It is worth noting that approximately everywhere in the world there exist the ABO trait in individuals. Notably, the passing on of this traits from generation to generation is aimed at enabling the future generation to adapt more to the environment they are exposed to. Adaptive traits are developed in a bid to adapt to the environment. Consequently, different environment suggest different traits thus can’t be used for classification purposes. On the same note, it is argued that this traits are liable to extinction once the particular adaptive environment is changed or does not exist anymore. Moreover, since the environmental factors change with time, new traits are likely to emerge in a bid to fit in to the changing environment. Consequently, since the emergence of traits is dependent on the specific condition that exists for instance environmental condition, numerous adaptive traits are expected thus the concept of adaptive traits cannot be used to classify humans since you may require an infinitely large number of subgroups. It is evident
