Scupin And De Corse's Theory Of Adaptation

He was intrigued and then he started doing more research because he had unanswered questions because he had key words like variation, geographic isolation, environmental changes, adapting (Scupin and De Corse, 1998). He started adding the puzzle that environmental changes can lead to species changing and also their genes changing because they have to adapt to the features of the new environment e.g. how to get food, how to survive from predators and how to survive from other environmental conditions. That all leads to the survival of the species that were able to adapt from that they will reproduce and form more species that are suitable for the environment because they inherited the survival traits. He noticed that noticed that although…show more content…
Genetic drift which is the non-random distribution of neutral genes helps explain the genetic different amongst remote populations. Gene flow help introduce new genes in the population gene pool through reproducing. According to Scupin and De Corse some cultures practice endogamy which is marrying someone of the same group to maintain the gene flow and also maintain human variation. All these factors help form evolutionary processes and cause human…show more content…
Physical environment causes human variation because the human species is very sensitive to change, so if the environment promotes growth or restrict growth using environmental factors weather changes, diet, land, humans in that population are bound to change because they have to adapt to the new environment (Scupin and De Corse, 1998). These factors contribute in human variation.
Culture is the most common cause of human variation in this modern life. People isolate themselves from others just because they have different beliefs, diets and outfits. They associate and reproduce together to maintain their culture, that inhibits gene flow and that influences human variation (Scupin and De Corse, 1998). The cultural differences are also influenced by economic and social advancement that also contribute to them isolating themselves and inhibiting gene flow (Thomas Sowel,
