is currently a substantial body of research supporting the argument that there is a genetic influence on numerous human behaviors‚ such as homosexuality‚ intelligence and personality. One indication that behavior has a genetic basis is that behavior is often species specific. Examples include the warning behavior of prairie dogs or the mouth to mouth sharing of blood amongst vampire bats. The closer our genetic resemblance is to a certain species‚ the more behaviors we have in common. Since long
