If values are same or similar, then population mean also will be the same. If values are different from individual to individual then population mean cannot tell about the distribution of values around the central value, the population mean.. Human variation: defined . Human variation refers to the fact that there are a range of possible values for each of the numerous physical characteristics of human beings.. People of the same species can have differing phenotypic traits that can be related to:. SP 6.1:. . The student can . justify claims with evidence.. Explanation:. . . In nature, environmental stimuli and changes in these stimuli provoke changes in phenotypes from all organisms in the environment—those species that do not adapt to these changes risk failure of surviving. Because of this one environmental change, many organisms make changes to their phenotype—such as a camouflage color change after pollutants distort environments color or larger wings that allow them to fly to higher regions where they can be safe from predators preying on those with the outdated camouflage—and these organisms all have different, respective genotypes. All of the organisms, with their unique genotypes, must adapt to this new environmental factor and produce a phenotypic response to better suit the environment’s demands. If not, they die. A real-life application of this scenario is the evolution of Peppered Moths in Industrial England, and provides solidified real-world evidence of this LO and SP. Moths in England were either light moths or dark moths, and their survival depended on the color of tree of which they were resting. When the industrial revolution occurred and copious amounts of soot was put in the air, trees turned dark from the pollution of the soot; this caused the light colored moths (evolved to be camouflaged while resting on the pre-industrial age trees) to be selected against by predators because the dark moths (previously selected against on the pre-industrial age trees) were now better camouflaged on the post-industrial age trees. The moths are now seeing more emergence of lighter colors, leading to their nomenclature.. Associate Professor. Variation. . Importance of variation. . Types of variation. . Phenotypic variation.
