The nervous system of a mosquito consists of about half a million neurons. That of a bee – of 800,000 neurons, of a dog – of 160 million neurons. A human has 85 billion neurons in the system. Modern computer systems contain only a few hundred thousand neurons and in rare cases, a few million, which, in terms of intelligence, is comparable to a bee. Bees are technically 100 times dumber than dogs and 100,000 times dumber than humans.
