Final answer:
The major biological concepts that are unifying principles shared between evolution and ecology are homeostasis and population dynamics.
Step-by-step explanation:
Two major biological concepts that are unifying principles shared between evolution and ecology are homeostasis and population dynamics.
Homeostasis: This concept refers to the ability of organisms to maintain a stable internal environment despite external changes. It is crucial for the survival and proper functioning of organisms. Both evolution and ecology study the mechanisms and adaptations that allow organisms to achieve homeostasis.
Population dynamics: This concept focuses on the changes in population size, distribution, and composition over time. Both evolution and ecology investigate the factors that influence population dynamics, such as natural selection, competition, and environmental conditions.
