10B [H] Yet mаny reseаrchers sаy that creativity and language in animals, like оther fоrms оf intelligence, have evolved. "People were surprised to discover that chimpanzees make tools," says Alex Kacelnik, an animal researcher at Oxford University. "But people also thought, 'Well, they share our ancestry - of course they're smart.' Now we're finding these kinds of behaviors in some species of birds. But we don't have a recently shared ancestry with birds ... It means that evolution can invent similar forms of advanced intelligence more than once - that it's not something reserved only for primates or mammals." What is the main idea of paragraph H (above) ? a. Primates and mammals are not the only ones with advanced intelligence. b. Humans have a common ancestry with other primates. c. Smart chimpanzees teach their young how to make tools. d. Some bird species like gray parrots are very intelligent.
