  • Change Gene Frequencies
    2,041 words
    ... ark moth variety. The light and dark moth varieties belong to the same species and interbreed freely. If pollution had continued, however, the rural moth population would have become entirely light and the industrial entirely dark. Then each population would be subject to somewhat different selective pressures because the two environments vary. In time, the dark and light populations would differ by groups of genes, with each group advantageous locally. The moth populations might eventually ...

  • My Hometown The Negative Changes

    Over time things change. Some things change for the better while other things change for the worse. One thing that's bound to change though is your environment.

I first moved to Gwinnett in Nine...
  • Their Dna To A Certain Population
    1,159 words
    Bill Law Intro. To Anthropology Prof. Salazar 4 February 2003 A Theory Evolves 1. Darwin was unable to explain the manner in which life, specifically the genetic makeup of a life form could change to allow natural selection to occur. The modern synthesis of genetics and the new evolutionary theory filled in the gap by explaining the occurrences of mutation and other sources of variation in a population through a genetic change in the populations DNA, whereby the population slowly changes until t...
  • Every Member Of Some Families
    1,024 words
    The Black Plague, which decimated medieval Europe, is by far the worst epidemic in recorded history, and quite possibly ever. One in every four or five people in Europe died, not to mention those in Asia, wiping out quite swiftly a huge portion of the world's population. That fact alone would obviously have a huge impact on customs in any town, and the communicable nature of the disease added to the effect of changing customs. Being too scared to come in contact with anyone that might be carryin...
  • Principle Of Organic Evolution
    379 words
    Are we evolving? And if so, into what? I most definitely think that we are evolving. "Evolution is all the change that have occurred in living things since the beginning of life". The same fundamental characteristic is shared by every and all-living things. For example, the fossil records, development, and biochemistry. Also Charles Darwin theory of education. Evolution is described as a process that involves a change in gene frequencies within the gene pool of a sexually reproducing population....
  • Differences In Dental Size
    658 words
    Dental anthropology is a tool recently developed by physical anthropologists to describe a given population biologically. The research potential of dental evidence remained under-utilized until the middle of the nineteenth century. It has lately been realized that dental variations, both morphological and metrical, provide valuable information for the reconstruction of phylogenetic relationships among different species (ancient and living), the comparative study of different primate groups, evol...
  • Genetic Composition Of The Population Changes
    247 words
    Evolution is one of the major unifying concepts of modern biology. Entailed with the concept of evolution, are the mechanisms that are involved with evolutionary change. There are many mechanisms that lead to evolutionary change. Random changes in the genetic composition of a population are called genetic drift. The mechanisms that cause random change include mutation, founder effects, and genetic bottlenecks. All genetic variation originates from mutation. A mutation is a hereditary change in t...
  • San Antonio's Increased Population
    341 words
    Developments have changed San Antonio quite a bit in the last fifty years. Change is necessary to adapt to a growing world. However, change must not destruct what once was. A hard balance we must make is to create and preserve at the same time. San Antonio's population has risen 22 percent in 10 years, making it the ninth largest city in the U.S. When population increases, the pressure on the surrounding natural resources increases as well. Changes are inevitably connected. San Antonio's increas...
