Two million years ago, the australopithecines were changing.
They began to use blunt stone tools to smash branches of trees for wood.
This was an important step in the evolution of man.
Today’s NZ Herald has an article called ‘See you later, suckers’ that begins:
“Our closest relatives in the animal world, chimpanzees and orangutans, have long been known to use tools. But octopuses?“
The article goes on to explain what the veined octopuses (Amphioctopus marginatus) do:
“They not only gather the coconut shells and stack them like bowls, but then carry them long distances, assembling them into armour when predators approach.”
