Primate Memory: Apes Recall Familiar Faces for Decades
A new study reveals that apes, including chimpanzees and bonobos, have an impressive memory, potentially surpassing that of some humans. Researchers conducted an experiment where apes were shown photos of old friends they hadn't seen in over 25 years. The apes displayed recognition and positive reactions towards familiar individuals, gazing at their images for a significantly longer time. The study suggests that apes possess cognitive mechanisms similar to humans, including long-term memory influenced by social relationships. The findings raise questions about the possibility of apes experiencing emotions associated with missing others. Further research aims to explore the nature of ape memory and its impact on their social interactions.
