Sexual reproduction

Stephanie Okolo BIO 119-001 18 April 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.…

Biologists at the University of California, Riverside have made an incredible evolutionary discovery that links sexual selection and placentation (Science Daily, 2014). The study of 150 species of Poeciliidae (Figure 1), describes the morphologies of males in species with placentas. Sexual selection- “special case” of natural selection, which acts on an organism’s ability to obtain, or successfully copulate with a mate, is not exceedingly important in species with placentas (Science Daily, 2014)…

When briefly taking a look how technology has changed society, many would say that it had made our lives exceptionally easier. This being said, it has also come with a profound cost. Walter Benjamin in his essay “The Work of Art in Mechanical Reproduction” discusses photography’s impact on our cultural perceptions of art. He argues that photography lacks essential characteristics of more established forms of creative visual representation which is otherwise known as aura. With this there is a…

Lewis vs Ridley In “Human Nature,” Matt Ridley argues that our entire purpose in life as human beings is reproduction. In From Mere Christianity, C.S. Lewis argues that we should strive for closeness with God over all else. I agree with Mr. Lewis. Though the Bible gives us the instruction to “Be fruitful and multiply” (Genesis 1:28), there is more to life than sex. This can be proven through the use of Lewis’ Mere Christianity and from my own experience as a Christian and as a human being. Lewis…

mosquitofish and perform a vertical life history analysis. Fish were captured and measured around Hennington pond at FIU, and data was compiled into a vertical life history table. This table revealed that the fish have relatively short life times and high reproduction rate,…

mainly helps us produces the female egg cells necessary for reproduction, called the ova or oocytes. The reproductive system is very important part of the body system because it helps the population to reproduce, it is a very crucial factor of living.The reproductive system helps our body to produce new cells. One of the most widespread diseases of the reproductive system is known as prostate cancer that only affects the reproduction cells. Prostate cancer mostly happens when the cells in the…

There are two main categories of reproduction, Asexual and Sexual. When only one parents’ cell is used in order to replicate or produce offspring is known as Asexual reproduction. This is very common amongst microorganism such as bacteria. Bacteria reproduce through a sub form process of asexual reproduction called binary fission. In addition to binary fission there is a processes called vegetative reproduction which involves vegetative structures, roots leaves and stems…

article delves into the help and hindrance of men. From Ridley’s perspective, males are useless as he further supports his claim “quote”. Key principles as stated in the article include man’s drive to execute violent crimes, poor pedigree, irrelevant reproduction value, and desire to fulfill an alpha role which promotes the previous assertions. Therefore, women exude superior qualities of the human race compared to men. Ridley argues why he believes males…

the way they do as a direct result of females. Ridley exposes both sides of the argument in his essay, but he stresses the fact that males are necessary. In a different part of the text, Ridley uses a metaphor comparing sexual reproduction to business. He considered sexual reproduction is similar to a business that is giving away 50% of the shares at the end of every year, which is terrible for the company. As stated earlier, Ridley says that in order to maintain a business that gives away 50%…

Rifkin’s article “Evolution’s Pregnant Pause: Artificial Wombs,” appeared in the Los Angeles Times in 2002, it successfully ask the question is artificial wombs waging a war against natural childbirth and women? This war has worried me because its purpose is to undermine the medical benefits of this technology. Traditionally women give birth, in which women are the principal caregivers of the children. Reading, Rifkin’s article he questions the parental responsibility and the role of women. The…
