What animal loves to bask in the sun, has sweat glands in their wrists, and is found only in Madagascar? The lemur! Lemurs are considered the world’s oldest primates! The story of lemurs begins over 70 million years ago, long before humans. At the centre of the lemur world is the female, who rises to the occasion of directing a social group. This happens quite rarely in mammals, where male dominance generally stands. Female lemurs snatch food away from the males, kick them out of sleeping spots, and show actual physical aggression.
