Human-like animals that walked upright were known as hominids. It is believed that the earliest hominids lived around 4.4 million years ago in the humid forests of eastern and southern Africa.
These animals, known as Australopithecus, are believed to have been around three to five feet tall, and probably fed on leaves, fruits, and the remains of dead animals. There is no evidence that Australopithecus made their own tools. There is, however, strong evidence that they used sticks and bones to help them dig and defend themselves.
What we must decide is how we are valuable rather than how valuable we are.
