Australopithecus were alive 4.4 to 1.4 mya. Lucy was alive 3.2 mya and her "baby" was alive 3.3 mya.

# data[].attributes.body
Homo Sapiens ate plants like fruits, roots, nuts, seeds, grains, tubers and animals like insects, fish, mollusks, birds, small & large mammals. Also they use fire to cook.

# data[].attributes.body
Homo Habilis lived between two point four million years ago and one point four million years ago.

Timeline of Homo Habilis compared to Australopithecus, Homo Erectus, Neanderthals, and Homo Sapiens.

# data[].attributes.attachment_caption
A comparison of skulls from Australopithecus, Homo Habilis, Homo erectus and Homo sapien.  

# data[].attributes.body
They had a slightly larger braincase and smaller face and teeth than in Australopithecus but it still retains some ape-like features.

# data[].attributes.body
Homo habilis lived in eastern and southern Africa.

# data[].attributes.body
Fruits, leaves, woody plants, nuts, seeds, and more importantly, meat and marrow from scavenged animals.

# data[].attributes.body
Homo habilis survived by having a pretty balanced diet. They used stone tools to protect themselves. With the tools, they cut meat and broke open bones.

# data[].attributes.body
Homo habilis died because of failure to adapt and climate change.

# data[].attributes.body
The homo habilis were the first people to make tools with anything like wood bones and stone.

# data[].attributes.body
Homo Erectus had long legs and could walk on two feet.

# data[].attributes.body
They developed walking upright, large brains, freeing hands for carrying/tools, and showing early, simple tool use (like cutting meat). They bridged ape-like and early human traits and put groundwork for the Homo genus species.

# data[].attributes.body
They lived between 1.89 million and 110,000 years ago.

# data[].attributes.body
They ate elephants, rhinos, hippos and bovine animals. They were heavily dependent on big game meat. They might have been the first humans to hunt.

# data[].attributes.body
Homo erectus looked very similar to what modern humans look like today. They had a brow-ridge to protect their eyes, long legs, and short arms. Homo erectus were about 4.9-6.1 feet tall, and weighed about 88-150 lbs. Lastly, they were the first humans to invent clothes.

# data[].attributes.body
They lived in the northern, eastern, and southern areas of Africa, as well as western and eastern Asia.

# data[].attributes.body
They needed a lot of protein to support their large brains and relied on large stone tools like a hand ax and cleaver. They also depended on fire to cook food, socialize, and keep warm.

# data[].attributes.body
Neanderthals used tools made from bone which was an upgrade from stone tools. They sharpened the bones and attached them to wooden shafts. They hunted in groups taking turns stabbing their prey.

# data[].attributes.body
Homo erectus went extinct because they were not able to adapt fast enough to climate change.

# data[].attributes.body
Neanderthals have created tools such as knives, arrow heads, spears, serrated saw-like tools, lissors, smoothed bone tools (often ribs) for rubbing hides to make leather. they also made things such as the levallo is technique, cave paintings, and types of jewelry clothing.

What contributions and progress did they make?

# data[].attributes.body
Homo erectus were the first to migrate out of Africa. They also were the first to use fire and cook food. They used handy tools like handaxes and stone tools.

# data[].attributes.body
From what we know homo sapiens came between 200,000 and 300,000 years ago.

# data[].attributes.body
Some scientists thought they were out competed by homo sapiens, where others believe that they interbred with homo sapiens and they both became one speices which is why some people have up to 4% of neanderthal In their DNA.

# data[].attributes.body
Neanderthals survived by caring for each other. Even though it is hard to know, some scientists think they were the first group to learn to care and help heal others.

# data[].attributes.body
Their front teeth were large, the central part of the face protruded forward and was dominated by a very big, wide nose, Neanderthals didn’t have much of a chin, but they did have broad shoulders and a body much wider than a homo sapiens.

# data[].attributes.body
Homo sapiens survived because they can adapt to food and climate. They used a lot of tools to survive. They learned from others mistakes and they are really smart. They also easily had baby's.

# data[].attributes.body
they had really big sculls because they had really big brains so they were very smart. they also had a more modern human carecteristics like short forhead and larger nose and high cheekbones.

What contributions or progress did they make?

# data[].attributes.body
Homo sapiens contributed and progressed in many things like advanced art, language, social networks, and tools like blades, spear points, and bows. And fire control, also seafaring.

# data[].attributes.body
Some tools that were used from the Australopithecus peoples were sticks and unmodified stones.

When Did Human Ancestors Start Using Tools?

# data[].attributes.attachment_link.description
The 3.2-million-year-old human ancestor known as Lucy sparked a revolution in scientists’ understanding of the origins of clever hands and stone tools

# data[].attributes.body
Neanderthals were “hyper carnivores” because of their excessive eating of meat. They did eat more though, like shell fish, plants, and nuts.

# data[].attributes.body
Lucy was an Australopithecus afarensis, an early human that walked on two legs. This species was a small-bodied, small-brained hominin.

# data[].attributes.body
This species of human survived through adaptability, using tree-climbing skills. They also used an omnivorous diet including tough plants, roots, insects, and scavenged meat. They also lived in social groups for protection, and found safety in trees or caves.

# data[].attributes.body
They were 4-4.5 feet tall and their skeleton points that they were bipedal. They were also hairy and had ape and human like characteristics.

# data[].attributes.body
The image demonstrates what Lucy and others could have looked like or not. It is likely that they all looked similar and did not live long.

# data[].attributes.body
Neanderthals lived in Europe and Asia, but most people in Africa have up to 4% of neanderthal in their DNA proving that homo sapiens and neanderthals interbred.

# data[].attributes.body
Neanderthals lived between about 130,000 and 40,000 years ago the oldest fossil being 130,000–170,000 years old found in Italy.

# data[].attributes.body
They had a primarily plant-based diet, relying heavily on fruits, leaves, seeds, roots, and possibly wood/bark.

# data[].attributes.body
The Australopithecus went extinct from climate change, diet changes, and just dying off.
