The biological perspective states that the brain uses a number of chemicals as messengers to communicate with other parts of itself and with the nervous system. These chemical messengers‚ called neurotransmitters‚ are released and received by the brain’s many nerve cells‚ which are also called neurons. Neurons are constantly communicating with each other by way of exchanging neurotransmitters. This communication system is essential to all of the brain’s functions. A tiny space called a synapse connects

These types of anthropologists focus mainly on identifying and constructing a biological profile based off of old/ancient remains. They do this by estimating age‚ sex‚ body type‚ and ancestry as well as identifying certain characteristics like diseases and injuries that could help in identifying the cause of death. To determine these things they start off by asking themselves a number of questions such as

within the Enlightenment period of 1700-1800. During the Enlightenment‚ much value was placed on scientific reasoning and methodology. This gave way to the conception of biological determinism‚ that because of biological factors‚ a person does certain things and behaves a certain way (Burke).
