Introduction
4 millions of years our planet has been floating in space millions of creatures have lived on at surface many acquainted being was among them but just affected only our human imagination for in the revolutionary struggle we are the only ones we’ve obtained the advantage of reason reaching it was far from easy. It’s origin dates back 20 million years to those fruit eating creatures that lived in African trees called proconsuls they were in trees far above terrestrial dangerous feeding on fruit and leaves depending on the species they buried in size from the marmoset to the gorilla.
Proconsuls
Hardly cared about the world below proconsuls climbed about the branches on all fours and almost exactly resembled the modern day macaque their upper and lower limbs were the same size they moved leaning on open palms instead of bended fingers quite a few fossils of proconsuls have been found in east Africa the score was primitive the brain small and rather simple yet the comparatively small size of their muzzle and canine teeth suggests non- aggressive Ness. One of the major features that lead to reason.
Ardipithecus
But 10 million years ago a drop in temperature made the African jungle sparse which rendered impossible to move from tree to tree via branches forced to leave the trees the descendent of proconsul Ardipithecus began moving on their rear limbs. Their feet were still prehensile but with special arches that allowed bipedalism the nearly complete skeleton of an Ardipithecus named Arde proves that these creatures were able to walk I’ll be at not as easily as we do.
The arms of Ardipithecus were kneeling and the hands were half human and half a blank. The first steps were taken to climb the next tree.
Didn’t want to leave tree crowd there habitual homes. They were indeed the intermediate between humans and apes as all of Arties features mediate entirely a blank and entirely human features.
Gracile Australopithecus
But life moved on trees became sparse and Africa turned into a boundless savanna 4 million years ago new creatures paste in the savanna Gracile Australopithecus.
They were well-adjusted to their new home their way of walking on two links was not so different from ours. They gathered and ate everything and were able to walk miles on it. Performed cohesive groups which allowed them to repel anything. They were curious at first glance. Was held on the upright neck the canine teeth got smaller in the brain bigger 3 million years ago. Aransas of east Africa evolved into the first humans.
Homo habilis
5 million years ago our ancestors crossed the Rubicon of brain size 7 00 g the first representative of our genes Homo habilis handyman.
Is name for a reason it was Homo habilis who is the first to make stone tools. Primitive choppers made from pebble with a few blow we’re still real tools for carving meat whittling wood defending from predators and killing prey man was now. Life in the trees was left for good and the savanna promoted forward movement perhaps our love for travel and exploration dates back to those times the world was perilous but intelligence made it possible to overcome difficulties it was not power or aggression. Genes that protected the first humans discover. Homo Habilis is very much like that of Australopithecus. 6 00 to 8 00 g now 1 1/ 2 times as much as its predecessors the face became smaller.
Gaster
Around 1 . 5 million years ago a new species appeared ammo or gaster workingman. They became the terror of the African savanna spirit and stone tools were an unprecedented phenomenon even the fiercest animals weren’t safe from harm now man became a hunter skeletons of antelopes and Ethan elephants surrounded by stone tools have been found in east Africa. Cut marks on animal bones are visible evidence of a gnu stage of a revolution possibly this is around the same time humans first discovered fire I’ll be at the evidence of that is rare and unreliable quite a few fossils of the first humans have remained in East Africa. Legacy in the skull was now in the past but their jaws were still large and their brains twice as small as ours they are height and build or exactly like that of modern humans their bodies except for their head hardly any different from ours they settled all over Africa and were the first to move beyond the last step was to colonize the planet so they took that step in the van. Expenses of the planet or conquered by new masters not right away though the planet didn’t give Manahati welcome nature should not be on. Addressed made it at all times life was no bed of roses human remains with marks of predators teeth bear witness to that yet it was hardship in gendered and fostered reason.
Homo heidelbergensis
Homo heidelbergensis were the first prehistoric humans whose brain size was equal to what we have now. Although their faces were still Savage there eyes shown with the renewed light of reason they built shelters buried their dead and created the first objects of art crude as they were man has gone through a long and difficult path of evolution what does the future have in store. Reason makes us responsible for ourselves now everything depends on us.
