Definitions:

Adaptations

Characteristics or traits that have evolved through natural selection, enabling organisms to survive and reproduce in specific environments.

Natural Selection

The process by which heritable traits that make it more likely for an organism to survive and successfully reproduce become more common in a population over successive generations.

Biological Systems

Complex networks of biologically relevant entities such as cells, organisms, or ecosystems that function through systematic interactions.

Interact

To act in such a manner as to have an effect on another; in biology, it often refers to the way biological entities, such as molecules or organisms, affect each other.
