Final answer:
Biological anthropologists use an evolutionary perspective to understand the development of life on Earth, including the principles of evolution and natural selection. Phylogenetic trees help illustrate the pathway of evolutionary history and connections among organisms.
Step-by-step explanation:
Biological anthropologists utilize an evolutionary perspective to understand how and why living organisms thrive. They study the principles of evolution and natural selection to explain the development of life on Earth. By using phylogenetic trees, scientists can illustrate the pathway of evolutionary history and the connections among organisms.
