RESEARCH NEWS: Apes Remember Friends They Haven't Seen for Decades
Apes recognize photos of groupmates they haven't seen for more than 25 years and respond even more enthusiastically to pictures of their friends, a new study finds.
The work, which demonstrates the longest-lasting social memory ever documented outside of humans and underscores how human culture evolved from the common ancestors we share with apes, our closest relatives, was published in the journal Proceedings of the National Academy of Sciences.
