Genetic Drift as an Evolutionary Force Becky Gonzalez Genetics 2450 Lab Section 1262 March 2‚ 2011 Genetic Drift as an Evolutionary Force Genetic drift‚ along with natural selection‚ mutation‚ and gene flow‚ is one of the basic evolutionary forces of evolution. Evolution is the method by which allele frequencies in a population change over time. This process can be random‚ where the changes occur through genetic drift (Hahn and Bentley 2003)

This approach is focused on how evolution has shaped mind and behavior. Michael Ghiselin coined the term evolutionary psychology‚ making him a key theorist. Other key theorists include Jerome Barkow‚ Leda Cosminde‚ and John Tooby. These three popularized the concept of evolutionary psychology with their book “The Adapted Mind: Evolutionary Psychology and the Generation

Evolutionary psychologists believe that aggression is linked through genes and has been maintained biologically as people have adapted to the changing physical and social demands of the environment. In the past‚ males that found other mates desirable found it necessary to compete with other males. The most successful male was the most aggressive. This aggressive behaviour made sure that the fittest males survived and were more successful in securing mates and passing on their genetic fitness to their

Some scientists believe that the female orgasm has a purpose‚ that is‚ it evolved for some adaptive function. Other scientists stress that there does not need to be a purpose to the female

is written mainly to remind myself of the steps I go through when making a map…much of this will sound like a lecture but it’s how I work and what I’m thinking‚ my steps might not be perfect and my observations might be incorrect. Next‚ look at a GLOBE of the earth not a flat map‚ this is because a flat map will distort things near the poles to make them look larger than they really are (Greenland looks huge on a flat map).

Evolutionary approach to food preference – perfect essay Evolution is the change in inherited characteristics of biological populations over successive generations. The environment our early ancestors lived in must be understood to understand why they adapted to certain behaviours or characteristics. This environment is known as EEA (environment of evolutionary adaption). Natural history and science have found that our species has spent much of its life as hunter-gatherers so by looking at their
