Discuss the evolutionary explanations of functions of sleep. (24 marks) The evolutionary theories suggest sleep has evolved because it gives an animal a greater chance of survival when in a dangerous environment. They also suggest that sleep has evolved because it conserves energy and coincides with their eating habits. The evolutionary explanation (also referred to as the ecological approach) is based on the observation of animals in their natural environment. The evolutionary approach to

Theories of Biology pg.1 The major theories of biology are evolution of natural selection‚ biological classification‚ inheritance‚ cells‚ bioenergetics‚ homeostasis‚ and ecosystems. Evolution by natural selection is a process that occurs over successive generations. Inheritance is a theory of how characteristics of one generation are derived from earlier generations. Cells theory is that all organisms are composed of cells and that all cells come from preexisting

Introduction A key concept in evolutionary biology is that divergent selective regime will often generate and maintain some type of phenotypic diversity (Langerhans et al. 2003). This divergent selection can lead to differences in phenotypic expression either by a genetic differentiation or phenotypic plasticity (Levins‚ 1968; West-Eberhard‚ 1989: Robinson and Wilson‚ 1994; Orr and Smith‚ 1998; Schluter‚ 2000; cited in Langerhans‚ 2003). Such divergence is significant as it can influence microevolutionary

Basic Biology Genetic diversity describes the genetic differences seen among members of a population. What this means that that every individual on the planet is different from one another in some way. This is because we have either high genetic diversity‚ or a low genetic diversity‚ which is seen through the size of the gene pool from which we came. If we happen to live in a gene pool that has a high concentration of genetic diversity‚ then we are more like to have many different genetic combinations

although Superintendent Kathy Cox has not commented on the theory of evolution itself; "the unfortunate truth‚" stated Cox as her rationale‚ "is that ’evolution ’ has become a controversial buzzword that could prevent some from reading the proposed biology curriculum" (Gross A10). Whatever her own beliefs on the subject are‚ however‚ the elimination of the term "evolution" may provide cool comfort to the theory ’s opponents‚ but its overall effect is merely to hamper the student ’s understanding of
