Humans, Have we always looked this way? Lived this way?
Australopithecines existed three million years ago. The development of hands and thumbs set them apart. So did the ability to spot a threat and retreat. They carried both traits of human and ape, and are considered gracile. They had no ability for language as per the size of the brain. Then again is it possible to know?
Two-point-five million, not the earliest state of being, but the Homo Habilis appeared and lived alongside the H. Rudolfensis. The Rudolfensis had a larger brain by 100 cm.
The Homo Habilis was an ape-like hominid, which closely resembled the African variety. The H. Habilis is considered smaller than the gracile and robust forms.
Dubbed the man of skill, he was found in a gorge In Tanzania. Initially believed to have a meat-heavy diet due to the tools found at the site. The tools were volcanic rock fashioned to have a sharp edge. However, discoveries of the limbs suggested a diet closer to modern apes than that of the hunter-gather type. Unlike primates, though they carried their food and other resources to a fixed location. While the Homo Habilis was bipedal, the Homo erectus was closer to the modern Homo sapiens of today.
What is fascinating is that it is suggested that they cared for the old and the weak while spreading. The development of fire, hunting, better tools, and language helped them reach anywhere from India to Europe, and southeast Asian.
After the Homo Erectus was the Neanderthal, a powerfully built race with slanted brows, and a projecting face. What is impressive is that even millions of years ago this race was trying to explain away and control the world around them. While they did care for the sick and dying they sometimes engaged in cannibalism. They also had some form of religion.
The Neanderthal survived in impossible weather through makeshift habitats. They also spread throughout a large area to Australia.
The next form is pure Homo Sapien. While Neanderthals had a good understanding of hunting, language, and tool making the Cro magnons( Now Early Modern Humans) had a greater understanding. They stalked their prey and were able to plan various projects.
Last but not least is the Homo Sapiens, dubbed themselves the wise men. The Homo sapiens invented lightweight bone and horn tools. The inventions of the fish hook helped to obtain more food. They spread from Europe and Southeast Asia through the Nile valley and Sahara.
History is always expanding. The understanding of each category increases with time. What is know today could be increased by next year. Look, to see the different sources of information available.
