Sociobiology is the examination of social behaviors as species evolve. Evolution occurs in the means of survival and these can adapt to what makes a species survive and grow. Sociobiology could be used as an ethical system because some ethical codes of conduct could develop through evolution and altruistic genetic traits passed down through family lines. Sociobiology believes that social behaviors and positive relationships are formed on the basis of biological and scientific evolution. The evolution of social codes that shape ethical choices, according to sociobiologists, consists of continuing the family lineage as in the case of kinship altruism, developing social protection contracts as in the case of reciprocal altruism, and strengthening numbers with group altruism. Christian ethics are based on a religious doctrine. The ethics deriving from faith beliefs are not perceived as biological, but as a choice to follow a religious code. Say no to plagiarism.

Get an original essay Christian ethics reject theories of evolution that contradict or undermine the ideology of their beliefs or morals. Christian ethics, or natural law, is the concept that God created moral behaviors and that humans have ethical dilemmas that revolve around choosing good or avoiding evil. Christian ethics believe in forgiveness for repentance for ethical behaviors that contradict their belief system. Sociobiology is at odds with Christian ethics. Aside from the obvious difference between evolutionary and creation theories, there are fundamental conflicts. Sociobiology believes that altruism is promoted by evolution due to the success in improving the species and increasing survival through these social behaviors. Christian law believes in altruistic behaviors resulting from God's influence and an individual's ability to resist evil. Christians reject scientific theories of evolution because it conflicts with their belief that God gave humans the right to choose good from evil. Singer argues that sociobiology cannot dictate ethical behavior and that reason is necessary to complement biology. What does he mean by this? How does he support his thesis? Sociobiology advocates making choices that may not be ethically correct, but Reason differentiates us from making ethically unacceptable decisions. Sociobiologists believe that every action you take should be done for the purpose of survival and passing on your genes to subsequent generations, which can lead to unethical decisions to protect your group or your young. This manifests itself through mutual, kinship and group altruism. The actions taken by an individual are aimed solely at the protection of their group, even if they sacrifice themselves or another group. Reason provides us with a moral code that we follow to know what is right and what is wrong. For example, in the case of group altruism, if there is a group of monkeys with a weakest link, sociobiology would tell the group of monkeys to eliminate the weakest link because it is limiting your success, but ethics and the reason they would explain is to feed the monkey back to health and stick together. Reason must be combined with sociobiology in order to make morally correct decisions. If you were to say that the behaviors and individuals portrayed were foreign to biology, you could not consider them ethical because the action would be the result of a primitive instinct rather than the moral code that we have evolved following..
