When primates grieve

The news today that the newborn gorilla at the Como Zoo has died brings two images to mind for us.

First, is this one from San Francisco Zoo, where a new western lowland gorilla died earlier this month when it was crushed by a door.

The remaining six grieved over the loss and comforted the mother, the zoo said.

And the other picture is this famous one, which showed the reaction of other chimps, when a dead chimp was removed from a rescue center in Cameroon.
