Sexual selection

certain aspects of their environment. Camouflage has become a common and taxonomically widespread adaptation that numerous prey species have adopted to reduce the likelihood of being either detected or recognized by predators. The theory of Natural Selection as put forth by Charles Darwin suggests that "those individuals who possess superior physical, behavioral, or other attributes are more likely to survive than those which are not so well endowed." (CITE) Having this ability increases the…

Social Darwinism and the Eugenics Movement Social Darwinism is the belief of natural selection that applies to social organizations and to individuals in society. The ones who were better suited would be well developed while those that were poorly adapted would suffer, this was Social Darwinism. Social Darwinism was created in the late nineteenth century. It was a highly developed movement that was involved with the theory of evolution. However, the theory was mainly based from the work of…

variation to be produced in population of organisms that can reproduce sexually by recombination and in individuals by gene and chromosome mutations. During sexual reproduction, progeny alleles from both parents and these have been migrated or hybridized, so that it may come from different populations and gene pools (Nee, 2004). Harmless mutation and sexual recombination may consent to the advancement of new-fangled…

In 1859, Charles Darwin challenged the traditional beliefs of divine creation with the publication of his book, Origin of Species by Means of Natural Selection. This publication started a scientific revolution with the theory that organisms were not created by a higher power but evolved over time by adapting traits that would maximize their chances of survival. This controversial subject came to be known as “Evolutionists vs. Creationists” and is still debated today (Davis 1999). There are four…

Although arguments for evolution dates from ancient times, Darwin’s idea of natural selection made evolution a plausible theory. The theory of evolution, “the blind watchmaker thesis” as Johnson refers to it, argues that purposeless material processes are responsible for the existence of the universe. This proposition provides the basis for…

The human desire to be with another is said to be one of the most powerful forces in the world. It inspires poems, songs, books and nearly every other creative media. From an evolutionary standpoint it is the reason that humans have been able to survive and thrive. Creating pair-bonds allow for bi-parental care and give the pair a sense of calm and joy, despite the struggles they may face (Acevedo & Aron, 2014, p. 1). But how is it that those pair-bonds stay together? Studies suggest that men…

Darwin derived the concept of the struggle for existence in part from Malthus's essay. He believed that creatures less fit for their environment would tend to die off. This would be called the struggle for existence. Some people thought that nature was a balanced system, but Darwin saw it as a mechanism. He believed the creatures that were best adapted would survive. Although Darwin agreed with Malthus on the struggle of individuals, he differed in opinion on Malthus's idea of the increase…

Several positions exist in philosophy regarding human nature. Karl Marx and Charles Darwin give two of these positions. Karl Marx’s philosophical position on human nature was that economic substructure and society determines human nature (Wall 279). He felt that humans are social animals that are driven to produce in a way that benefited society, and that human nature is “expressed in a drive to spontaneously and creatively produce products in a manner that is conducive to social and…

Evolution has always been a subject of questioning discussion ever since Charles Darwin established the theories of Natural Selection and Descent with Modification. According to Darwin, some animals were born with certain characteristics that became advantageous for their particular environment. As time passed, however these organisms modified some of these physical characteristics that they were born with in order to survive in their particular environment. This modification allowed the…

Theories and studies in science tend to change over the years due to new evidence as well as social changes. Science, like a living organism, adapts and is reevaluated with new outcomes. It is important to look back at past studies and ideas not only to retest hypotheses but also to see how far the scientific community has brought society. One branch to look back on would be biology, more specifically human variation. At the present time we know that race is not a biological variation. All…
