known as natural selection. The survivors are the ones who adapt best to their environment and are then able to reproduce. This means that there genes carry on through the generations and we gradually see the preferred characteristics for survival become more common. Over time the human race will become more and more adapted for survival on earth and this process is called evolution. Psychologists look at the behavioural aspects of people in order to work out whether the behaviour of humans has been

2014 Natural Selection by Charles Darwin Understanding Natural Selection stresses the theory that a genus’s environment determines the likelihood of survival. Charles Darwin explains the importance of natural selection and sexual selection. Natural selection affects a given organism in its specific environment and how they adapt. Sexual selection focuses on a male and female relationship. Throughout the passage‚ Darwin gives various examples that define the meaning of each topic. Natural selection

Darwin is one of the most well known scientists to date. Darwin’s book On the Origin of Species by Means of Natural Selection was highly controversial and not widely accepted. The ideas Darwin wrote about in his book had never been heard before and went completely against the church. Darwin said that all species on the Earth originated from one common ancestor. Then as time went on‚ that one species adapted differently based on the environment they were in. This kept happening until they became completely

natural selection‚ evolution‚ mutation‚ variation‚ heritability‚ and fitness. EVOLUTION IN ACTION Darwin envisioned natural selection acting so slowly that its effects would be imperceptible in a human lifetime. But in the late 1900s‚ evolutionary biologists began to detect small but significant changes taking place in a handful of species. In the past decade‚ many more cases of natural selection have come to light‚ and scientists now realize that species can adapt quickly to changes in their

the relationship of plants and animals all over the world. He observed organisms on islands off the coast of South America and those on the mainland. His observations showed that these organisms were related‚ but not identical. This led Darwin into believing that over time‚ organisms must adapt to suit their environment. He explained his theories thoroughly in his book‚ On the Origin of Species by Means of Natural Selection. Darwin decided it was possible for a species to change from one form

genetic makeup of the gene pool of a population. It refers to the change in allelic frequencies that occur from generation to generation. There are three ways that microevolution can occur: mutation‚ genetic drift and natural selection. Mutation is the change in a gene of the DNA of an organism. This may change an allele and possibly the alleles frequency in the gene pool of the population. Genetic drift is an unpredictable change in a populations allelic frequencies from generation to generation. Genetic

to generations by natural selection. In addition‚ he stated how there are four objections to the theory of natural selection‚ how species can win the struggle for existence through natural selection‚ and how the origin of species challenges religion. Central to the theory of evolution‚ is natural selection. Evolutionary theory was developed by Charles Darwin to explain the ways in which animals adapt to their environments (Akert‚ Aronson‚ Sommers‚ and Wilson 43). Natural selection‚ is the process by
