"There is one 1-year-old, that's the youngest, and they go up through grandmas and grandpas," Baeckler Davis later told The Dodo. She added the oldest ones, who go up to around age 50, were likely taken from the wild.
While the video above is heartwarming, it's also a reminder of just how much life the chimps missed while trapped inside a lab - and how many more "firsts" they have to experience at their new home.
"It's a whole new world for these guys," Baeckler Davis said.
