Long Memory of Apes Amazes Scientists
come to be: to happen or develop into something over time
Apes, like chimpanzees and bonobos, can remember people and other apes for many years. Christopher Krupenye, a scientist, noticed this while visiting zoos around the world. One day, he saw a bonobo named Jasongo recognize a researcher he had not seen for years. Jasongo was very happy to see the researcher again.
In a study, Krupenye and his team used eye-tracking technology to find out more. They showed photos to the apes and found that the apes looked longer at pictures of those they knew before. Some of the apes remembered others even after 26 years.
This research suggests that the common ancestor of apes and humans could remember others for a long time. Krupenye says this discovery helps us “understand what’s special about our species and how we came to be.”
