Question

which of the following statements best explains why evolution is relevant to understanding human form and function? multiple choice selection pressures cause organisms to become extinct. our evolutionary relationship to other species is helpful when selecting animals for biomedical research because their anatomy and physiology is most similar to ours. organisms adapt so they may better cope with the challenges of their environment. for research purposes, evolution allows us to obtain predictable results of how every species will respond to drug interactions because we all share the same common ancestor. understanding evolutionary relationships allows us to understand which species are more closely related to humans, and thus more important to preserving on the planet.

Explanation:

• Option 1: Selection pressures causing extinction is not directly related to understanding human form and function.
• Option 2: Evolutionary relationships mean species with closer relationships to humans have more similar anatomy/physiology, which is useful for biomedical research to understand human form/function (e.g., using animals as models).
• Option 3: General adaptation to environment doesn't specifically tie to human form/function understanding.
• Option 4: Evolution doesn't make drug responses of all species predictable, as species diverge and have unique traits.
• Option 5: Preserving species based on relatedness to humans is about conservation, not human form/function.

Answer:

B. Our evolutionary relationship to other species is helpful when selecting animals for biomedical research because their anatomy and physiology is most similar to ours.
