More than three million years ago, our ancestors were already on the march, rising on two legs to search for food, seek greener lands and, above all, to grow in body and brain. Let’s meet some of them:
1. Australopithecus afarensis
They had ape-like faces and their brains were a third the size of modem humans’ brains. They lived 3-3.9 million years ago. Fossils were found in Ethiopia in 1974.
2. Paranthropus boisei
Covered with fur, they had strong arms and gorilla-like faces. They lived 1-2.5 million years ago. Fossils were found in Tanzania in 1959.
3. Homo habilis
Homo habilis, which actually means "handy man", was the first species to make and use primitive stone tools. They lived 1.6-2.2 million years ago. Fossils were found in Tanzania in 1960.
4. Homo erectus
With skeletons very similar to those of modern humans, they were probably the first to use fire. They lived 30,000-1.8 million year

the school. So I can know what happens to him. Last Friday Carl came to our city again. He hoped to stay with his old grandpa during the summer holiday. He’s taller and stronger than before. We swam in the river outside the city together or had a picnic on the island. It surprised me that he has learned to cook when we were travelling in the wild forest. He told me his parents were both busy and sometimes he stayed at home alone and he had to look after himself. "How do you like your school" I asked. "Wonderful," said the young man.
