    Australpethecus 3.2 million years ago
    Australpethecus was found in a dig in 1974. This sketal system was named Lucy. Lucy is believed to be the oldest human ancestor. Lucy is bipedal, making her a hominid. We can almost be certain that Lucy is a human ancestor because she has a deep heel imprint and her bones are thicker than those of a modern ape.

    Australopithecus (cont.)
    Australopithecus developed the ability to walk on two feet, bipedal, while it lived in trees of the patchy African Savannah. It was mainly an omnivore. It's main sources of food were fruits, tubers, nuts, and occasionaly meat. Lucy was primarily prey and had to flee most of the time
  • Homo habilis- 3.0 million years ago

    Homo habilis- 3.0 million years ago
    Homo habilis was duscovered on a dig in 1960. He has the ability to make stone tools, this is mainly because he had an enlarged brain cavity. These stone tools helped Homo habilis with an increasing of his diet.

    Homo habilis (cont.)
    Homo habilis lived in Africa. During the time that Homo habilis lived there the temperature increased. This increased in temperature caused the woodlands to disappear. The rotation of the earth also switched giving the earth seasons. Homo habilis mainly grazed on grass or other vegetation with an occasionaly piece of meat that was left on a dead carcus. They extracted the meat by using the stone tools that they made.
  • Homo erectus 1.8 million years ago - 300,000 years ago

    Homo erectus 1.8 million years ago - 300,000 years ago
    Homo erectus looks more and more like modern man. He is taller, had more muscles, yet he was more slender than his earlier ancestors. Homo erectus was also smart. He bettered the tools that were first made by Homo habilis. Homo erectus also invented fire.

    Homo erectus (cont.)
    Inventing fire helped Homo erectus in many ways. It bettered their habitat. The habitat was mainly in the bamboo forests of Asia or dense forested areas of Africa. The fire allowed them to protect themselves at night. It also allowed them to better their diet. They had an omnivorous diet. However, their diet was different from their earlier ancestors. Homo erectus ate large quanties of meat.
  • Neanderthal (230,000 to 28,000 years ago)

    Neanderthal (230,000 to 28,000 years ago)
    Neanderthal was a short, stocky man with a long face and a projecting nose and and forehead that stuck out. They mainly habited Europe, Central Asia, and the Middle East.

    Neanderthal (cont.)
    Neanderthal was primarily a hunter. He had developed better tools and hunted with larger hunting parties. Being a hunter Neanderthal's diet mainly consisted of large quanties of meat, but they were still omnivors.
  • Cro Magon (10,000 years ago)

    Cro Magon (10,000 years ago)
    Cro Magon looks like a modern human does. They lived in tents that were made of mammoth skins. They were still bettering the weapons and tools that were made better by Neanderthal.
  • Cro Magon (cont.)

    Cro Magon (cont.)
    Cro Magon invented the spear thrower. They also used bows and arrows to hunt and harpoons to fish. The Cro Magon diet is omnivorous but had large quantities of meat. These meats were mammoth, reindeer, red deer, bison, wild horses. They also included fish in their diet.
