In the wake of Jane Goodall's death, the many scientists and others influenced by her are promising to do their best to carry on her legacy.

FILE - In this Sept. 2, 2019, file photo, a silverback mountain gorilla named Segasira walks in the Volcanoes National Park, Rwanda. A crowded mountain can make silverbacks more violent, scientists say. Mountain gorillas spend most of their time sleeping, chomping leaves and wild celery stalks, and grooming each other’s fur with long, dexterous fingers. Around that time, three large family groups splintered into multiple smaller units, and the overall population also grew. The dissolution of the larger family groups – one had included 65 individuals – was probably related to the deaths of charismatic silverback leaders, said Stoinski.
