It is getting harder and harder to hang a unique trait on our species. Beavers engineer, and crows, vultures and dolphins use tools. Bees dance, cockatoos drum, and whales sing. Elephants can communicate across long distances, and otters play. Aristotle said that Man is the only animal that laughs, but chimps, gorillas, and orangutans are known to crack up, especially if tickled. The research of Dian Fossey and Jane Goodall shows that the higher primates wage war and commit murder.
So what makes homo sapiens different from the other species on the third planet out from an average star in the Sagittarius arm of the Milky Way galaxy?
Man is the only animal that cooks.
