    Selection is the idea that individuals in a given population with certain traits will survive and produce more offspring because they have certain desired traits. In turn, this will create a change in the population. There are three main ingredients that are necessary for selection to occur within a population. These three ingredients are variation, differential success, and heredity. Variation is the differences among individuals in the composition of their genes. Genes are what determine…

    Darwin’s theory of evolution and natural selection are concepts well known by most people. Evolution being a change in a population over time and natural selection essentially coming down to survival of the fittest and being a key mechanism of evolution. In the case of seahorses, rather the 54 species of marine fishes in the genus Hippocampus, the male and female seahorses have evolved a series of unusual adaptations for the purpose of increasing their overall fitness. A common misconception…

    In 1911, the problems and invalidness of scientific racism became more exposed, especially the main problem with it. The main problem with racial science was its inability to distinguish between phenotypical, genetic, biological, and cultural variation among the human population along with having insufficient and invalid evidence to back it up. Franz Boas questioned and challenged the beliefs that race, culture, and language were all connected. He studied and observed different skulls of…

    For at least the past several decades, scientists have been attempting to provide solid scientific support for a biological basis for homosexuality. Findings have supported a genetic contribution at least as regards male sexuality, but evidence has been conflicting as to whether there is a link to one or more specific chromosomes. Other biological causes have also been explored, but the debate has continued over whether homosexuality is biologically based or a choice. This paper will include a…

    The natural simulation done in class was a good representation natural selection in the wilderness. The four things that Darwin identified that must be present in order for natural selection to occur are genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction. This activity demonstrated all these factors except genetic variation. For over production of offspring, the beans’ populations were multiplied by three after every round. This is…
