What specific biological mechanism did researchers identify explaining size variance between human and gorilla penises?
Answer
Differences in gene structures related to cell proliferation during development
Researchers found specific differences in the genetic pathways responsible for cell proliferation during the developmental stages, which accounts for the final organ size variance observed between humans and gorillas.
