their environments. Evolution and Genetics • Evolution is defined as: changes in allele frequencies of a population over time • Any physiological or morphological changes not represented in germ cell genes will not contribute to evolution Genetic variation Due to random mutations, differences exist in the genetic code (genome) between the individuals of any given species. This is called genetic variation. For a given allele, particular genetic

dependence on technology. Technology also has the ability to change the appearance and genetics of the next generation. An arising method of genetic engineering has the ability to genetically modify the DNA of a fetus to resemble specific traits. Initially, it may sound like a genius discovery. However, this procedure could change everything we know about our world. It goes against nature and can lead to severe problems. Genetic Engineering has the potential to benefit many people. New discoveries have been

Nature vs. Nurture Troy Crosland WGU Issues in Behavior Science GLT1 Nature vs. Nurture Issues concerning the nature vs. nurture debate are amongst the oldest in science. This debate centers around the argument of biological and genetic contributions as opposed to those imposed on human development from environmental factors. Many scholars such as Descartes and Plato suggest many of our individual traits are inherited from our parents, they happen naturally regardless of any influence from
