Why do some researchers suggest that mirror neurons are crucial to the development of modern humans?
A. Without mirror neurons, major milestones in the evolution of humans including the use of tools, the creation of fire, and the cooking of food would never have occurred.
B. Without mirror neurons, some humans might have discovered how to use tools, create fire, and cook food, but these skills would not have transferred to all humans because humans could not imitate without mirror neurons. If humans had not learned these skills, we might not have evolved the same way.
C. Without mirror neurons, humans would never be able to recognize their reflections, so they would not be able to recognize that other humans are like them. Thus, the social groups that are so crucial to human survival would never have formed, and humans would have died out.
D. Mirror neurons are not crucial to the development of modern humans.
