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)…

stretch itself. This is where boys start to be averagely taller than females. This part of puberty will affect that athlete’s height and weight for the rest of their lives. If a male volleyball player that is six foot eight inches tall, decides to have a sex change. That transgender woman regard-less of the therapy that is given already has gain an advantage over the female athletes (Yilmaz). Therefore, having a six foot eight inch tall girl volleyball player would help be able to dominate on…

and interprets perceived differences among humans and gives us ‘feminine’ and ‘masculine’ people” (Shaw & Lee, 116). Typically, one of the most exciting moments during a woman’s pregnancy is when the doctor informs her of the sex of the baby. Immediately after learning the sex of the baby, the woman, her family, and her friends begin…

In recent years, girls have started playing on boys’ sports teams. This is becoming so common that it doesn’t surprise anyone when they hear that a girl is on the boys’ team. Female athletes should not be allowed to play on male athletes’ teams after elementary school. There is a much higher of injury for the girl and having a female teammate might become distracting to the other players. With all of these issues, is having a girl on the team really worth the worry? Boys and girls of the same…

society. Despite these contradictory messages, most of the women she interviewed understood that being feminine is about being wanted by men but not wanting sex in return. By demoralizing societal deviances in other girls, they were able to raise their own status and portray the ideal feminine characteristics. Girls who participated in multiple sex partners and promiscuous behaviors were seen as passive recipients of boys and were…

Sexual selection has long been recognized as a powerful evolutionary process having 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…

professional sports, the Olympic games, and other elite sporting events alike will be open to a whole new category of competition. As new competition arises, there will have to be measures placed to regulate these events. It is argued by Müller (2016) that sex is an arbitrary measure of who should be competing against each other in sports. Elite sporting agencies such as the IOC have no leniency when it comes to male and female competition. They are strictly prohibited from competing against…

Sexual Response Cycle The basic construction of a human being is the same between male and female, both male and female have: veins, arteries, heart, brain, nervous system, etc. Biologically men and women have a similar sexual response cycle. Physically men and women respond in a similar fashion as well, since humans are built in a similar way the human body reacts in similar manner sexually. The go through the different phases of the cycle: excitement, plateau, orgasm, and resolution. Even…

as well as the life I lived.” Organ donations are surprisingly not that common as one of would think. Many people believe that if you put that you are an organ donor, on your license that the paramedics won’t try as hard to save you, since they can save more than one life. Organ donations help save people’s lives every day, giving kids the chance to grow up, or the chance for parents to see their kids grow up. With that being said, there are many people against organ donations, but there are…

In “Alcoholics and Liver Transplantation”, Carl Cohen and Martin Benjamin discuss whether alcoholics should get equally organs like others (patients) and who should receive transplanted organs. This is one of the most issues that arises and brings attention to the public. Cohen and Benjamin present this discussion by providing two arguments. The first argument is moral. Base on moral, alcoholics should not get the treatment for their transplantations. The reason is that they should blame for…
