cousin of Charles Darwin who introduced to the world the theory of evolution, Galton incorporated Darwin’s idea of survival of the fittest into his notion of eugenics. The goal of eugenics was the improvement of the human species through the careful selection of parents. Galton identified two primary processes to achieve this end. Positive eugenics encouraged individuals who were above average both mentally and physically to produce more offspring. Negative eugenics proposed that individuals who were

Beren Robinson Field Study A field study by Beren Robinson on the threespine stickleback fish in the lake of coastal British Columbia showed some evidence of divergent natural selection. First, the study will be described. Next, the findings for the study and how the findings support evolution and natural selection. Finally, a proposed second study will be given. Study Description Beren Robinson reason for the field study was to determine if the constraints of two distinct environments

populations evolve over the years through a process called natural selection. Darwin realized that in a population, more individuals were born than could possibly survive, he also recognized that the individuals that survived and reproduced were the ones with some sort of competitive advantage over rival animals, therefore they were more likely to pass their useful traits down to their offspring (Darwin, 1859). As this process of natural selection occurred for millions of years, these desirable traits that

Parallel Evolution and Inheritance of Quantitative Traits Hypothesis: * Do the similarities in the lateral armor plates of the Threespine Stickleback indicate parallel evolution in a species? Methods: * The differences in plate number and body shape were examined in two populations of threespine stickleback in both a stream in Canada and a stream in Japan. Both populations were feral and completely independent of the other population. The researchers made three hybrid crosses by breeding

4. Searching for a key of a given value in a list Brute Force Sorting What would be the most straightforward method for solving the sorting problem? Reasonable people may disagree on the answer. Selection Sort or Bubble Sort Brute-Force Sorting Algorithm Selection Sort : Scan the array to find its smallest element and swap it with the first element. Then, starting with the second element, scan the elements to the right of it to find the smallest among them and swap

review of the ethical issues that are commonly raised in the debate between non-medical sex selection and natural selection. Background information on sex selection technologies is provided, as is a description of the process regarding the medical procedure. Arguments for and against gender selection will be explained and compared and conclusions will be drawn. Included will be the pros and cons of gender selection. Finally, the views of people I know as well as my own. Aside from cases in which it

between Natural Selection and Sexual Selection There are debates raging on whether to regard natural selection and sexual selection separately. On one hand is the argument that the two are mutual and in particular, that sexual selection is a part of the natural selection. On the other hand is the contention that the two are exclusive of each other because the manner in with each selection progresses (Andersson & Simmons, 2006); (Kokko, Jennions & Brooks, 2006). For instance, natural selection is not selective
