2,412 words... d warming of climate where there is an increase in the growth of plant material and plant foods. This change would have promoted a growth in subsistence farming, at the very least. This would have increased the amount of plant carbohydrates and thus there was an increase in the occurrence in evidence of caries. Again in the Mesolithic there is further warming in the surrounding climate to the point where an even greater amount of plant food harvest is attainable for human consumption. Frayer...

Hardy Weinberg Genetic Drift
1,115 wordsThe Hardy-Weinberg theorem states that the frequency of alleles and genotypes in a populations gene pool remain constant over the generations unless acted upon by agents other than sexual recombination. For example, take a population of mice that consists of 1, 000 members. A specific allele, albino allele, is recessive within this species. 80 % of the population expresses the normal phenotype- brown coloring, while the remaining 20 % are albino. 640 members of the population have the genotype A...

Controlling Deer Overpopulation Through Increased Hunting
1,515 words... nth's, high deer populations can deplete food sources critical to their own survival. It can take many years for damaged winter habitat to recover (38). When this depletion of their own food sources exists deer become sickly and weak. Its not uncommon for overgrown herds to live in poor health and to be much smaller in stature then a herd of normal abundance. Shedd and Monahan show that, deer in an over populated area weighed thirty percent less then deer of acceptable numbers elsewhere (6)....

Population Growth Population Increases
1,455 wordsModeling Population Growth First of all, lets give definition to population growth. The term basically explains how the population changes with time (decreases or increases). It is controlled by the death and birth rates. According to the main ideas of modeling population growth, the rate at which a population changes depends on at least three factors (Modeling Population Growth: Main Ideas, n. p. ). Lets examine the models of animal population growth and the three factors depending on which the...

Million Years Ago 65 Million Years
3,666 wordsIntroduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar...

2,179 wordsChina s One-Child Policy: An Economic Perspective on Governmental Control In 1979, China implemented a one-child per family policy in order to address the issue of unchecked population growth for a country with limited resources. Because China is one of the most densely populated countries in the world, concern for the issue of overpopulation and the capacity of the Chinese government to address the needs of such an overwhelming population directed the impetus for the implementation of the polic...

Populations are divided by geographic boundaries, confining a specific region / group of people to share and distribute its genetic traits within themselves without outward influence. The size of these populations is dependant upon whether certain mountains, rivers, deserts, oceans, or other extreme geographical, cultural, or technological conditions determine the tendency for isolation or migration.

Fire suppression has allowed forested areas to achieve a climax state, which provides less forage for wildlife. While terrestrial wildlife is benefited by fire, large fires through the increase in sediment flow negatively impact aquatic ecosystems. Fire is essentia...
