Question

question 2 2 / 4 based on the article, which of these is true about chins? a. chins are the small bones that all human - like creatures have shared. b. chins have always been very good at protecting the jaw from breaking. c. chins could help scientists understand why humans and bonobos are alike. d. chins could help scientists understand why humans have survived. submit

Explanation:

To solve this, we analyze each option based on typical knowledge about chins (from anthropology/biology context):

• Option A: Not all human - like creatures (e.g., some early hominids) don't have chins as we know, so A is false.
• Option B: Chins aren't primarily for jaw protection; their function is more related to human evolution, so B is false.
• Option C: Chins are a human - specific trait, so they don't help show similarity between humans and bonobos (bonobos don't have chins), so C is false.
• Option D: Chins are a unique human feature, and studying them can give insights into human evolution and survival advantages, so D is true.

Answer:

D. Chins could help scientists understand why humans have survived.
