Biological anthropologists view how humans come to be the way they are as the result of
fomenos

Both their own individual life experiences and the evolutionary history.

<h3>What about biological anthropologists?</h3>
  • Since genes are the main cause of human diversity, they can look at genes.
  • Since differences in health are the primary cause of most human diversity, they can research health.
  • Understanding human adaptation to various settings, the causes of illness and early mortality, and how humans descended from other animals are all goals of biological anthropologists.
  • They research people (alive and deceased), other primates including monkeys and apes, as well as human predecessors, to achieve this (fossils).
  • The study of biological anthropology focuses on the variety and environmental adaptations of our closest living relatives, monkeys and humans, as well as their evolutionary history.
  • The strong evolutionary perspective of biological anthropology is one of its key features.
