The most important factor in the evolution of mating systems is the survival of offspring. This “makes sense” because the mating systems that worked (produced offspring), are going to be repeated in the succeeding generation. If a mating system is unproductive, their will be no offspring to continue doing…
Sexual selection can be used to explain certain characteristics or behaviours which increase an individual’s reproductive success. These characteristics may get exaggerated over evolutionary time. In humans, these characteristics may include good physical and mental health, as well as physical features such as good looks etc. these characteristics are attractive because they show an ability to reproduce and pass on these genes to offspring. There are two types of sexual selection, intrasexual and intersexual. Intrasexual selection is the evolution of characteristics that enable an individual to compete with their rivals whereas intersexual selection is the evolution of characteristics that are attractive to a mate. An example of this would be a peacock’s tail. The peacock with the ‘best’ tail (longest and brightest etc.) is considered to be more attractive to the peahen and therefore he is more likely to reproduce and pass on his genes to the next generation. Buss, 1989, found evidence to support this. Over 10000 participants across 37 different cultures took part in his study on differences in intersexual selection. Questionnaires were given to the participants, asking about preferences for variables such as marriage, age differences, characteristics etc. He found that women valued qualities such as ambition and industriousness in men – qualities showing their financial potential. He also found that men valued youth and physical attractiveness more highly than women. This suggests that males look for qualities associated with fertility in line with evolutionary predictions. He concluded that women have evolved to select mates who can provide resources for themselves and their offspring. Buss’ study had over 10000 participants and therefore has credibility, however the participants may have not given a truthful answer and instead given one they thought would appear more…
Evolutionary theory states that all animals are motivated by the desire to ensure that their genes make it into the gene pool of the next generation. Natural selection is the tendency of individuals best adapted to their environment to survive and pass on their genes. Sexual selection is the probability of passing on our genes depends partly on any chances of survival but also on ability to attract a mate. Those who have genes for features which make them attractive are most likely to reproduce and pass all their genes on. This could be supported by Darwin’s suggestion that the peacock’s bright colouring was there to attract the peahen. Sexual selection is important for us as humans as some physical characteristics may not have developed to increase our survival rate, but simply to make us more sexually desirable. An example of this is eye/hair colour and distribution of muscle. Our sexual behaviour can be influenced genes, and this is similar no matter what culture you come from. They are also similar in terms of physical characteristics. This is a significant factor because it is a demonstration of the universal…
The nature of sexual selection is derived from the evolutionary theory. This suggests that the people who we choose to have sex with has been born into us and is an innate response we have. It also suggests that all behaviours are adaptive, including relationship formation, therefore forming a relationship should help out ‘survival’ in the way of passing on our genes.…
With reference to Ageism Negative and Positive by Erdman B. Palmore page 4 Robert Butler, the director of the national institute on Aging has introduced the term ‘ageism” in 1969. He called it another form of bigotry and noted it is similar to sexism and racism. His definition is and I quote’ process of systematic stereotyping and discrimination against people because they are old (p.35, 1995). Webster dictionary (1994) defines it as prejudice, discrimination against a particular group especially the elderly. Three examples of ageism that I have personally witnessed are forced retirement and abuse of the elderly and the one that I have committed is saying aloud that they have no need for sexual satisfaction. These instances are damaging to…
Cumming – According to Cumming older people will become more 'individual' as they have grown up and this process is natural for elderly people. They also start caring less about people views and opinions on them.…
A variety of theories have been proposed over the years to explain why sexual reproduction may be more advantageous than asexual reproduction, and, for that matter, why sexual reproduction even exists at all. For years everyone accepted the general proposition that sex is good for evolution because it creates genetic variety, which, in turn, is useful in adapting to constantly changing and challenging environments. But it may give organisms a very different kind of edge.…

Teresita went to a fraternity party because she'd heard that this fraternity "really knew how to have fun" and she really needed fun after a disastrous academic week. She knew that some women had been taken advantage of at previous parties, but she put that out of her mind, as she downed one drink after another. Just when things were getting dull, the coolest guy on campus took her by the hand, led her upstairs and talked her into having sex. The next day, Teresita noticed that her vagina was bruised and bleeding. She barely recalled having sex, but knew who was responsible for her condition, and filed rape charges against him with the campus administrator.…
Aging and gender impacts in our society in different ways and there are many issues where…
In America, beauty is associated with being young and having flawless skin and no wrinkles. A woman in late adulthood could look in the mirror and sees wrinkles, age spots, bags under her eyes, and sagging breasts; she might think she is not beautiful. What are older women supposed to do? Should they deny their sexuality because American society reveres youth? The youth obsessed American culture creates a stigma against the older adult, especially females since men are perceived as sexier with age. Once a woman can no longer bear children or loses her mate, people might think she becomes asexual. The truth is sexuality continues throughout the life span, but many women accept…
Older adults often work with their spouses who need to be cared for due to long term illnesses up until their death, as well as grandchildren and foster children. Many older people take care of their grandchildren because their own children have to go to work or because they have been granted custody due to abuse or incarceration of their children. Many older people who have been given the responsibility of raising another child so late in their life are faced with additional health issues, psychological stress, and social isolation. It is often very stressful for someone who is older to have to be a caregiver because they are already dealing with other stresses of old age such as losing their spouses, not having a lot of energy, and worrying about their own health.…
I am going to do an interview on a LGBT community member and disuses how sexuality effects their development. During the interview I will be asking three main questions to the member of the LGBT community. First question is going to be the LGBT member’s self-identify, and then I will ask about the society’s perception of their community and last will be asking the impact of same-sex marriage has had on the LGBT community. Those three main areas will complete my interview with the LGBT member.…
The aging process involves many changes. These changes can be difficult for some. Changes include physical and cognitive development including primary and secondary aging, intelligence and memory, health and biological factors, relationships, personality, and transition factors (grief and loss issues, and retirement). I will address the above using scholarly peer reviewed journals.…
From a purely reductionist perspective, we are simply "ugly bags of mostly water" (to use a phrase from Star Trek) for our genes. The main reason we have sex is so our genes can last. The reason that there's sexual dimorphism (as opposed to having only females reproducing asexually) is so the gene pool can be enriched and it is thus capable of withstanding sudden changes in environment. This is actually the reason why there is sex in the first place, but having dimorphism means having a gene pool (thereby phenotype) that's more varied.…
