The Biological Approach

Describe And Evaluate The Biological Approach The biological draw close is divide up into three main principals; Physiology which is an investigating into the brain, dying(p) system, hormones and how they work. The investigation of heritability, visiting the role that genes may have on our behaviour. And likewise the comparative method which is the when animals argon studied and so compared with kind-hearteds. The absolute majority of cells in the human body withstand a core, the nucleus contains 46 chromosomes, these are made up of a chemical substance c totallyed deoxyribonucleic acid (also know as DNA). The DNA in apiece chromosome carries information called genes. For our wide-cut life these genes influence our body and all its functions. Research on the influence of genes has often been carried out on animals such as rats. Psychologists stick out then manipulate certain genes so they can measure the effects on human behaviour. Selective breeding, catching eng ineering and genetic mapping programmes attend us understand the genetic basis of behaviour. Bock and Goode install that when mice were raised by themselves they were more scrappy and tended to attack new(prenominal) males when exposed to other animals for the first measure. The mice were never brought up or taught to be aggressive; this was simply just their behaviour.

This study shows that thither was a genetic tendency for aggression. This study can be explained by the growth of behaviour. The evolution of behaviour was originally founded by Darwin in 1859, this is the opening that all things have evolved over time from their ancestors through the inborn selection process. Natu ral selection tells us that the strongest ge! nes survive and are then passed onto the next generation whilst weaker genes lastly die out. scientific evidence was provided to show that either species had fit to their environment and thus survive or render maladjustive and therefore become extinct. Examples of evolutionary behaviour can be seen in wildlife where sexual...If you trust to get a full essay, grade it on our website: OrderEssay.net
