Document Summary

Enter the world with predisposed biological mechanisms which make us behave and act in certain ways. How have behavioural traits and tendancies evolved and developed over time. Biologically based mechanisms receive information from the environement, process and respond to it. Wolves demonstrate the evolved biological and behavioural responses to their environment. Change over time in the frequency with which particular genes and characteristics occur in an inbreeding population. As certain genes become more or less frequent the characteristics that they influence also change. Some differences are due to mutations in gene reproduction during cell division. Even before darwin, people knew that breeding two organisms with desired traits could yield a desired species. Increase the liklihood of survival and ability to reproduce in a specific environment, thus will become more common over time. Natural selection acts as a set of filters allowing for certain characteristics of survivots to be passed on and make extinct undesirable characteristics.
