Koko, the smart gorilla, has a message for the leaders attending the 2015 COP (Conference of the Parties) in Paris. This meeting attracted world leaders, celebrities, and other environmentalists because the imminent dangers of greenhouse gas emissions have worsened and immediate actions need to be implemented. Do you think that animals like Koko who has the capacity to communicate to humans are additional proofs that chimpanzees and humans may have come from the same ancestors as Charles Darwin postulated? Explain briefly.
