  • Choose Two Animal Organ Systems That Show Evolutionary Change

    Evolution is a process of gradual change over time in both body and corresponding behaviour (Open University Glossary, 2013). The evolution of animals’ and humans’ nervous systems is a necessary process to maximise the chances of survival. Neuronal and behavioural changes are closely linked to the environment surrounding animals and humans, as well as to their lifestyles. This essay will present some evidence that the nervous system of animals and humans have evolved as to maximize survival, by looking...
