While robins fledge at an early age, condors stay with their parents for years. Male and female wolves raise their puppies together. But animal species may also differ in the content of their emotions. Evidence that elephants feel compassion or sorrow does not mean that hippos feel compassion or that penguins feel sorrow. Perhaps they do, perhaps not.
Animals also differ from one another as individuals.
Among elephants, for example, one may be timid and another bold. One may be prone to attacks of rage, another peaceable.
