Document Summary

Trophy hunting and inadvertent evolution: a case study. Trophy hunting removes the largest and strongest individuals from a population, preventing populations from recovering. Harvesting of species may also affect sex determination in some species. Biological evolution is the change in organisms over time. Evolution includes the relatively small fluctuations that occur continually within populations, as when the genetic makeup of a population changes from one year to the next. Genes are composed of dna, and they specify how to encode proteins. A given gene can have two or more forms (known as alleles) that result in the production of different versions of the protein that the gene encodes. The genotype of an individual can be designated by the letters that represent the individual"s two copies of each gene. Evolution can be determined as change over time in the frequencies of different alleles in a population.
