The Biological Approach

Describe And Evaluate The Biological Approach The biological antenna is divide up into three main principals; Physiology which is an investigating into the brain, flighty system, hormones and how they work. The investigation of heritability, interpreting the role that genes may have on our behaviour. And likewise the comparative method which is the when animals ar studied and thusly compared with kind-hearteds. The absolute majority of cells in the human body cut back a core, the nucleus contains 46 chromosomes, these are made up of a chemical substance c totallyed deoxyribonucleic acid (also cognize as DNA). The DNA in apiece chromosome carries information called genes. For our stainless 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 weed then manipulate certain genes so they can measure the effects on human behaviour. Selective breeding, transmittabl e engineering and contagious 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 opposite 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 phylogenesis of behaviour. The evolution of behaviour was originally founded by Darwin in 1859, this is the conjecture that all things have evolved over time from their ancestors through the intrinsic selection process. Natural selection tells us that the! strongest genes 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 wherefore survive or mother maladjustive and therefore become extinct. Examples of evolutionary behaviour can be seen in wildlife where sexual...If you wishing to get a full essay, grade it on our website: OrderEssay.net
