Chimpanzees can remumber faces for years, Reveled by study

Humans have the ability to identify and remember faces from a very young age. Newborns often show their choice of seeing faces. With their growing up, this ability also gets better. Identifying the face is a holistic process. In this, the brain remembers faces in a holistic manner rather than personal characteristics. 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 conclusions have revealed the long-term memory of Chimpaji and Bonbos. The effect of their social relations on the memory of the monkeys has also been indicated by this study. It is a matter of fact that the period and type of this social memory is almost equal to the long-term memory.” Earlier in some studies, chimpzis had some ability to react to humans.
