Question 1:
Altruism is a behavior that benefits another individual despite the cost to oneself (Sparrow and Spaniol, 2018). Consequently, altruism in humans may have evolved as a result of either kin selection, group/multilevel selection or reciprocal altruism. By definition, kin selection involves the tendency to assist those of close relation compared to those more distantly related to oneself (Chaung and Wu, 2017). Secondly, multilevel selection theory involves group led benefits where the fitness of the group outweighs the costs to the individual (Ogorman et al., 2008). Thirdly, reciprocal altruism comprises cooperation between individuals where one helps another with the expectation that the other individual will help them out in return at a later date (Takano et al., 2016). Of the three types of altruism, I hypothesize that kin selection best explains and fits with the evolution of altruism in humans.
The kin selection hypothesis, also called the inclusive fitness theory, predicts altruistic tendencies will be higher towards another individual when the benefit to the individual and relatedness are greater than the cost to the actor (Foster et al., 2005). …show more content…

These naturally occurring processes allow for lateral gene transfer between prokaryotes. For instances, prokaryotes are capable of taking up DNA from their environment in a process called transformation, transfer genes through transduction with phage particles, and many other gene transfer processes (Ku and Martin, 2016). The transfer of genes may increase the mutation rate in the genomes of these organisms with the insertion of new DNA segments into their own genome with deleterious, beneficial or silent effects with the potential to increase the rate of change in organisms and thus the rate of
