The Darwinian concept of sexual selection involves the vox populi that any physical trait that enhances reproductive success leave behind gradually be passed down and enhanced over evolutionary time. Evolutionary psychologists explain the relative hairlessness of humans in terms of sexual selection, as this trait was adaptive in that it enhanced reproductive fitness by indicating hygiene. It has therefore evolved and passing-developed over the centuries as it confers a net benefit. Intra-sexual selection involves workforce competing with each other for access to females. As a sequel of this, men declare evolved larger, more triangular backs, as this indicates cleverness and makes the individual more attractive to females; another example of sexual selection at work. Inter-sexual selection on the other hand, involves the unpatterned choosiness of females. Females invest highly in their offspring, and as a consequence, look for partners that can provide resources and protect them from predators. As a payoff of sexual selection, both males and females have evolved certain jibe preferences which in turn, has lead to the evolution of certain physical characteristics.
Current mate choices evolved in the EEA, and were adaptive in mobile hunter-gatherer tribes.
These choices now subsist as neural circuits which warp our mate preferences. An example of this bias is the desire for attractive, symmetrical faces. Little & Hancock propose that humans have evolved to be attracted to symmetrical faces because they indicate averageness, which equates to communicable health. Furthermore, it has been proposed that sexual selection has caused males to develop fairly large testicles, as this is a way of compensating for female promiscuity. Studies show that chimpanzees, which have highly promiscuous partners, have large testes, whereas gorillas, which have faithful partners, have relatively small testes. Humans are somewhere in the...If you want to get a full essay, order it on our website: Orderessay
