Humans are also known for keeping a long period of time due to the ability to remember people. However, there is not much information about what kind of ability is in monkeys. Recently published in Proceedings of the National Academy of Sciences Study I have given some interesting conclusions about this. It states that Chimpaji and Bonbos have the ability to identify faces and they can recognize the face even after being separated for 26 years. Researchers have found through an eye tracking test that Chimpaji and Bonbos take longer to see the older peers of their group than strangers.
This indicates a long-term memory of chimpzis to identify the face. An interesting thing in this is that their duration of looking towards the face seems to be associated with their previous relationship status. They see the faces with whom they have closeness. It can be assumed from these findings that the excellent memory of humans can also be in chimpy and bonebos. It can also be the reason behind this being a common ancestor millions of years ago.
Laura Lewis, the first writer of this research, is associated with the University of California, Berkeley in the US. Lewis told The Guardian, “These findings have revealed the chimpy and Bonbos being a long-term memory. The effect of their social relations on the memory of the monkeys has also indicated this study. It is a matter of time that the period and type of this social memory is almost identical to the long-term memory of humans. ” Earlier in some studies, chimpzis had some ability to react to humans.
