Bees have only a few milligrams of brain, but they can perform certain tasks like mammals, such as leading roads for companions and building homes   Elephant brains are five million times larger than bees, but they operate inefficiently  Nerve signals are transmitted from one end of the brain to the other, and between the toes of the brain, 100 times as long as bees
Bees have limited brain capacity, but they can maximize the function of the nervous system
  Some people think that the human brain may not be as extreme as elephants or bees, but we will be smarter if we have more neurons through evolution
