Aggressive behavior heredity and environment essay

The other side, however, says some so called predispositions are in fact learned behavior or environmentally influenced. Direct comparisons were made between the one and two-factor models that are in hierarchical relationship i.

The saturated model with equal means across twin and zygosity group was thus used as a basis of comparison for other more highly constrained bivariate genetic models. Gene-Environment Interactions There are theories, however, concerning genetic and environmental influences, which seem to suggest an interaction between the two and one such theory is the general arousal theory of criminality.

But it is nurture, or the environment that takes the innate tendencies and molds them as we grow to adulthood and on. Some extremists went as far as saying: A final measure suggested for defining antisocial behavior is by examining personality traits that may be influential in the criminal behavior of individuals.

He did propose a theory of heredity pangenesis based on a now discredited view of the influence of the use of traits on reproduction, but it was never essential to the theory of natural selection. People react in different ways when frustrated.

Children whose biological fathers had been convicted of property crimes were more likely to engage in similar behavior, when compared to those biological fathers who had been convicted of violent crimes. Many of these scientist maintain they can train or teach anyone to be anything they choose for them to be, totally discounting natural variations.

Whether this is true or not is not relevant to evolution as such, for if it is true, then it is true of everything, and not just living things. Obviously, from this list of neurochemicals it seems plausible that there is a genetic component to antisocial or criminal behavior.

Although not mentioned extensively in the text of the paper, there is a great need to try and identify those individuals, especially children, who may become susceptible to certain disorders or personality traits that can lead into antisocial, delinquent, or criminal behavior.

Additional criticism was given and adopted from Gerhard Gruber. Today, a new approach to deal with this question is emerging. Replication Rules must involve what Dawkins calls "high fidelity" replication. A study conducted looked at thirty two MZ twins reared apart, who had been adopted by a non-relative a short time after birth.

Here, nurture represents our surrounding: The future for some children is made worse when ADHD and CD are co-occurring because they will be more likely to continue their antisocial tendencies into adulthood Holmes et al.

Siever LJ Neurobiology of aggression and violence. The basic argument has one side contending the people act as they do because of genetic predisposition or animal instinct.
