Chimpanzees
Chimpanzees and bonobos are fiercely intelligent creatures with complex social hierarchies. That’s not really surprising, considering they share 98.7 per cent of their DNA with humans. Chimpanzees are famous for their great variety of tool use and both species are excellent problem solvers.
The Royal Zoological Society of Antwerp found that bonobos were better at solving puzzles than chimpanzees, beating them in intelligence tests. However, this appeared to be largely down to the persistence of one individual bonobo.
