Problem: Imagine two groups of primates. One group is known to learn socially by observation, while the other exhibits only individual trial-and-error learning. Imagine that one individual in each group learns a new foraging skill, such as using a rock to crack open hard nuts.
A) What prediction can you make about the number of individuals in each group that will display this skill over time and why?
B) Could you argue that the original individual exhibited insight learning and how could you strengthen or refute the argument?
