Evolutionary Adaptation Of Pregnancy Sickness

3. Discuss how pregnancy sickness might be considered an evolutionary adaptation.

Pregnancy sickness is an evolutionary adaptation to help the offspring survive. Pregnancy sickness expels any food intake that could be harmful to the fetus. Without pregnancy sickness, many offspring would develop deformities or the mother would miscarriage. Also, it follows the three main points that determine an adaptation. Pregnancy sickness follows reliability because all mothers experience pregnancy sickness, regardless of severity. Secondly, pregnancy sickness follows efficiency by successfully expelling any harmful materials that could affect the fetus. Finally, pregnancy sickness follows economy by not costing the mother more than a few moments of sickness,

The two ways that sexual selection occurs is through intersexual competition and intersexual selection. Intersexual competition is competition between members of the same sex for mates. The victor in the competition is allowed to mate with the opposite sex either directly or through control of territory and resources desired by the opposite sex. Intersexual selection is when members of one sex consensually agree upon desired traits for the opposite sex. The greatest example of intersexual selection is the male peacock’s large bright feathers. The large feathers of the peacock hinder its ability to survive in its natural habitat. However, the large bright feathers are desired by the female peacock. So although the feathers negatively affect its ability to survive, the male peacock’s bright feathers positively affect its chances of

Name and define the three products of evolution.

The first product of evolution is adaptations. Adaptations are an inherited and reliably developing trait that came into existence because of natural selection because it solved an adaptive problem. The second product of evolution is by-products of adaptations. A by-product of an adaptation does not solve adaptive problems and is not relatively functional. The third product of evolution is noise. Noise are random effects caused through mutations.

10. Provide a detailed definition of evolved psychological mechanism as proposed by evolutionary psychology. Demonstrate a human trait that fits your definition.

An evolved psychological mechanism is a set of processes during which a historically recurring specific survival or reproductive problem faces an organism, this allows narrow information to bring about a determined output behavior that leads to solving the problem. An example of a human trait that follows this definition would be a human’s fear of snake. Throughout human history, humans have been innately scared at the site of snakes. When a snake is spotted, a human is put in a specific “survival” situation, during which the human is triggered to be scared of the snake. This leads to the human avoiding the snake to
