Some scientists propose that due to human activity and climate change, a sixth mass extinction has already begun. Which of the following best describes what occurred during the periods indicated by the arrows? Observed modern extinction rates will resemble the rates found early in previous extinctions. B. The MC1RD allele is not responsible for dark coat color in the Carrizozo population, so the dark coat color is likely a result of convergent evolution.
