Selection

present due to a powerful directional selection from domestication in these animals. Domestication could be an example of convergent evolution. It shows what happens to a species when there is a powerful directional selection within the species. An example of directional selection would be the behavioral effect of an animal being tame. Wright uses another animal example in the article. The silver fox shows evidence of that domestication can be recreated through selection lines. The selected…

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…

“ A man who dares to waste one hour of time has not discovered the value of life” (Charles Darwin) Charles Darwin is one of the most responsive scientists of the nineteenth century. Charles Darwin's most famous act as a scientist was to change the way people look at living things. Charles’s childhood and educational background was very unique. Charles Robert Darwin was born February 12, 1809 in Shrewsbury, England. His dad was Robert Darwin and his mother Susannah Darwin. He had had five…

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…

regarding the costs and limits of phenotypic plasticity. Ultimately, phenotypic responses to changing environments involve both plastic and genetic contributions. Individuals are able to accumulate genetic variation through adaptation-when natural selection favors genotypes that are best suited to the local environment. To grasp this idea, we can look to the variation in humans. Populations living in areas of high sun exposure, such as countries on the African continent, have genetically darker…

How does competition change a species? If a certain species are better at competing than another species then they will survive and pass on their genes to future generations, and they will be good at commission. Light vs Dark Fur. The light color mice had to evolve to the new dark rock background, The mice with the Dark colored fur were able to survive on the dark rock background. The light colored mice were unable to blend into the background. But they started to evolve so they blended and…

Procurement strategy selection In a traditional procurement strategy, the design and construction work will be separated. A design team will be employed to carry out the design drawings, specification and the bills of quantities. While the design stage is completed, contractors then received the Architect drawings and carry out the construction work. The contractor always involved a number of nominated sub-contractor to assist particular items of the work. Due to the separation of the…

1859, Darwin published his book called Origin of Species. In his book, he talked about his theory of evolution and his travels around the world discovering this phenomenon. Darwin was the first person to publish the theory of evolution by natural selection. During Darwin's educational period, he studied medicine, but he had to stop when he found out he could not handle…

further back than the United States itself. Darwin proposed that morality was an adaption which evolved by natural selection both at an individual level and a group level. Morality or a strong commitment to virtue helped group cohesion and lead tribes with more virtuous members to take over other tribes which did not. In his book The Righteous Mind, Jonathan Haidt argues that group selection shaped the modern landscape as groups competed against one another for survival. The group with the most…

RESULTS: An experiment was conducted to document the patterns of evolution in the fictional species, Cannus stannous. Fitness of the C. stannous population is determined solely by its ability to retain heat. Three genes determined heat retention; can size, skin type, and water level. Each gene had three alleles, producing 27 possible phenotypic combinations (Table 1). The data recorded pertains to two populations of C. stannous over 9 generations; a small population of 4 cans (Figure 1) and the…
