Female reproductive system

2016 How female choice governs sexual selection. Sexual selection is perhaps one of the most intriguing phenomena in the mammalian kingdom. It is the functional relationship between phenotypes and fitness that enables successful genes of parents to be passed down to their progeny. One important mechanism of sexual selection is how we have evolved to have complete autonomy with whom we reproduce with, especially how that choice relies heavily with females. The captious nature of females makes…

and food preparation is the significant part of reproductive labor especially since there is more down-streaming investment to food processing industry. Whilst, productive labor is a labor economically valued in a market place, reproductive labor is concerned to pose no economic value in a market place. Reproductive labor is more associated with private sphere; labor often done by household member for other household members. However, reproductive labor are typically done for free, which makes…

of reproductive labor appears. “Exchanges of power (Hobbes) or labor (Locke) have contractual…

What is mate choice? How did it evolve and why does it differ between sexes? To answer these questions, we first have to understand what it means to be female and what it means to be male under evolutionary standards and how the two sexes contribute to reproduction. Under biological terms, a female is the sex that produces the ova or egg, which is the larger sex gamete. The egg is large because it contains nutrients and material needed for the development of offspring as well as the DNA of the…

important consequences on reproductive behaviour, morphology, and fitness (Birkhead and Pizzari, 2002). Sexual selection research has often focused on pre-copulatory mate choice; however, the discovery of female promiscuity and polyandry has lead to the realization that mate choice continues to operate after copulation (Birkhead and Pizzari, 2002). For males, it is obvious that promiscuity has evolved to increase reproductive fitness; however, the potential benefits to females are less…

This writing focuses on “The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male-Female Roles”, written by Emily Martin. The main idea focuses and talks about how science represents sperm as a higher status and masculine. While the egg is a lower status and feminine. Thus, supporting that males are dominant and that there is gender related inequality. Today’s society is constructed of stereotypes based on our cognizance of the world that we live in today and…

society that have always viewed females as being inferior to their male counterparts. According to the four elements theory, women are inferior because their bodies contain less fire. Women were also deemed as being inferior in their rational capacity in relations to math, science, and philosophy. To further add, women were said to be inferior in their physiology and reproductive capabilities. In the movie “The Handmaid’s Tale” we see where the male generated a view of female inferiority, that…

through “penis fencing”. Penis fencing is a reproductive practice that is practiced by only free living flatworms. In penis fencing, each of the individuals has the opportunity to inject the other with the male gametophyte, or sperm. All flatworms have the male reproductive organ, or the “penis”. They also all have both male and female reproduction systems. When two flatworms are ready to commence the act of reproducing, they both erect their reproductive organs and attempt to pierce through…

Throughout the span of human existence males and females have had different reproductive strategies that are relative to the reproductive success of each sex. They are learned at a young age, usually in the first few years of life when the mind is most susceptible and malleable to new information. Children learn these strategies through parental influence and through the more modern invention, schools. Schools reinforce evolutionary reproductive strategies through the teacher’s behaviors and…

sex and biological reproduction impacted the division of labor and the origins of gender roles in early male and female hominids and Homo sapiens. I will also address how the advancements in the technology of biological reproductive control, has affected and shaped modern day gender roles. The major drive for early hominids and Homo sapiens was the acquisition of food and reproductive success which was essential in their survival. Biologist suggest that with the development of bipedalism came…
