Zelikov Human Selection due to Eye Color The Laeng (2006) paper reflects on various topics that include, but not limited to the sexual selection of blue eyed individuals. The paper provides what seems to be relevant information to why individuals with the recessive blue-eye pigmentation select for individuals with the same genetic marker. The reasons reflect the acknowledgement of paternity for blue-eyed males due to the recessive trait disappearing when in the presence of a foreign allele. The evidence provided by Laeng (2006) is reinforced by various studies conducted by Little, Samules, Frost, and Hickens as well as the lack of absolute certainty of males siring their own children. Problems faced by the article were the narrow selections of participants in the study geographically and culturally. Laeng (2006) reflects the concept that individuals with both copies of the allele for blue pigmentation often find individuals with the same traits more attractive. The article provides that knowledge of paternity for the male is the driving force for the selection due to the recessive characteristic of blue eye pigmentation. Frost (2005) study supports Laeng (2006), but not directly. Frost (2005) focuses on the northern migration of individuals from Africa and the change of labor roles due to migration. As groups traveled further north, resources such as nuts and berries became scarce, forcing women and men alike to adapt to the environment. Women began to focus their energies on building shelters and processing meat, while men focused the majority of their energy hunting. Due to the terrain of northern areas like the steppe, men would be away from home for prolonged periods hunting and the paternity of their children can come into question very easily (Frost 2005). By selecting for traits in females, such as eye color which are recessive, the males could distinguish their offspring from that of 1

Zelikov another’s. Doing so for an extensive period of time would change the frequency of blue- eyed individuals in northern European areas as well as cause male offspring to favor blue-eyed individuals through imprinting. The selection of blue-eyed individuals can then be adhered to an ontological view in areas studied in Laeng (2006). By doing so, Laeng (2006) conclusion is supported.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
