Sexual selection

Dr. Roughgarden’s talk discusses the evolution of gender and sexuality. She challenges Darwin’s Sexual Selection Theory which suggests that males are created with a higher sexual drive than females are. Along with this idea, Darwin implies that females are attracted to males whose appearance is, in simple terms, beautiful. Dr. Roughgarden disagrees with this and offers some examples as to why this theory is false. One of the examples that most interested me was her explanation of homosexuality…

inconclusive findings (see Balliet et al., 2011 for a review). A contemporary explanation for sex differences in cooperation and generosity derives from sexual selection theory suggesting that attractiveness could moderate generosity. Attractive people are treated favourably in a number of contexts (see Langlois et al., 2000; Maner et al., 2003). The sexual selection hypothesis has been tested by researchers who have argued (and found) that males and females are more generous and cooperative…

The underlying reason that we as humans cannot follow the advice of Jesus of Nazareth is that we are selfish. What this quote is saying is that what ever action or item you would want to get from someone you should return something of equal value. Having that sense of equal reciprocity is against human nature. Throughout the history of human evolution, it is the selfish ones that survive (Dawkins 2006) . Selfishness goes along with competition with both starting very early in our evolutionary…

around the mechanisms and social context of Cryptic Female Choice in Black Widow spiders.

When talking about the issue of whether we should elect or appoint a judge, I believe that we should use merit selection. With merit selection I believe that this could help pull the system away from politics and focus more on how the…

Genetic engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. This type of technology gives parents and doctors an almost “G-d- like” position. Should parents be able to choose certain traits for their children if the children cannot give consent to this? Are their safety hazards to this picking and choosing? According to…

II. The protagonist, Eadlyn, Changes throughout the book. Before the Selection begins, Eadlyn, comes off as bratty and spoiled, and has a hard time opening up to people.

They are talking about clothes, and sketches they’ve made of designs, when Hale asks, “Could I see them? Your sketches” (Cass 133). Eadlyn…
