This debate speculates whether nature or nurture has the most effect on human beings when it comes to areas such as homosexuality, intelligence, and criminal behavior. Today, most people settle on one side of this eternal debate, and do so with proper explanations and evidence as to why their position is the correct position. Those who choose the nature side insist that our DNA and genotype is what dictates who individual human beings are and what personality traits they will have. The nurture side argues that humans are a product of their environment. So, although the nurture angle has good arguments, the nature angle uses the biological makeup of humans, brain matter, and genes that can affect how we turn out in order to demonstrate that nature does in fact have a greater effect on the sexuality, intelligence, and criminal behavior of human beings. Sexual orientation is heavily determined by nature through epigenetics, which are chemical modifications of the human genome that alter gene activity without changing the DNA sequence. The Science, a magazine, recently posted an article which explores the role of epigenetics in homosexuality. It explained a study of male twins which found that epi-marks, chemical changes to chromosomes which are usually erased when eggs and sperm are produced, can be
