Selection

Currently, many individuals still believe that evolution did not occur and is merely a myth created by non-believers and scientist. Evolution, simply put, is decent with modification(Berkeley). The canny resemblances between monkeys and humans are extradentary examples of our descending from a common ancestor; thus, giving us ground against the falsifying of our evolutionary tree. With advances in technology, we are capable of observing our genetic similarities with other species and can almost…

responsible for the evolution of certain animal behaviors and cultures. Dawkins's definition is a unit of information in a brain, exchangeable within a society. It results from an assumption that cultures evolve as living beings, and variations by natural selection. Like the gene, the meme is the basic unit in this…

Kuhelj and Virant-Doberlet conducted their study, “Male-Male interactions and male mating success in the leafhopper Aphrodes makarovi” in order to be able to determine how male-male interaction is correlated to their reproductive success. The researchers had first hypothesized that a female leafhopper is more likely to mate with male who exhibits a higher effort in their calls. The males with the longer or louder call would be more likely to get a longer response from the female, which in the…

which theorizes they could walk on land at some point, millions of years ago. Vestigial organs show changes in the human body over time, because at one point, those organs were needed for proper body functions. But through evolution and natural selection, animals have outgrown the need for certain parts of their…

published on Friday in the journal Science uses life history theory to explain why tropical songbirds typically raise fewer chicks than temperate songbirds. What’s life history theory? Life history theory seeks to explain the ways in which natural selection works to determine a given organism’s anatomy and behaviors. Life history theory suggests that reproductive tendencies, or “life history strategies,” are part of a complex system of species traits, or “life history characteristics.” Parent…

Natural selection has a filtering property in that maladaptive traits, whether behavioral or otherwise, get selected out of the gene pool. Conversely, learned behaviors are mostly not under the influence of natural selection, and while they may be beneficial, they need not be adaptive. For example, cultural behaviors may play a big role in development, but does not…

In the employee selection process organizations use different techniques to test and predict potential job performance. An employee’s past performance in other positions is a good indicator of future job performance. During the hiring process applicants provide information as verification that the individual is suitable for the position. Employers are able to predict employee performance by requiring a minimum level of education or training to be hired in the organization. Within the text, it…

Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the…

Marx and Darwin are two 19th century thinkers that transformed their respective fields with their revolutionary theories. Marx criticized the class system and its progressive oppression of the working class, creating a communist ideology. Darwin introduced the theory of evolution into biological thought to explain species’ development and extinction through time. Although Marx focuses on the social evolution of class antagonism and Darwin writes about biological evolution, Darwin’s work…

Although society has grown to accept individuals with mental disabilities it wasn’t always so. This paper will speak about significant contributions and theories of psychologists and the development of selective breeding. In the 19th century, a social movement claiming to improve the genetic qualities of human populations was developed. The process of improving the human race through the production of superior offspring was known as Eugenics (Boring, 2010). The idea that created eugenics started…
