WHO WERE THE FIRST SETTLERS OF PLANET EARTH? The planet earth is theirs, Some people need reminding .. ;) 70 million years ago, among mammals different types of monkeys called primates evolved. The name Primates was first used by Linnaeus in 1758 in their taxonomic management of animals; means first in Latin. Linnaeus included in your order Primates humans, apes, monkeys, Old World and New World monkeys, the rest of mammals which he called Secundates (seconds). The first primates were small animals, nocturnal, living (almost always) on trees. Over time, some of these were changing their habits and physical characteristics: his skull was older, he grew his brain could grasp objects with his hands, suit up and eat fruit and vegetales.Del common core of primates, there were two branches of monkeys: 1) of the Apes: chimpanzee, gorilla and orangutan 2) hominid or proto, giving origin of modern humans Hominids or humans first: It is named for one of the two families of monkeys in the group of primates split. While family orangutan, gorilla and chimpanzee was no change, 15 million years ago in the family of hominids began the evolution to the man actual.Los early hominids and the long road to the man: Various were the species joined the modern man with the earliest hominid. The species represented true evolutionary leaps, ie, true moments of change were: 1.- Australopithecus (southern apes) was the first bipedal hominid (walked on two legs and could run on flat ground). He had powerful jaws and strong molars. Long limbs and spent much of his life in the trees. His brain had less than 400 cubic centimeters volume. It follows that upright walking occurred much earlier than brain expansion. Its size does not exceed 1.20 m. high and 30 kg. of weight. Age: 4 million years The first Australopithecus was found in the 1960s in East Africa (Ethiopia) and was named Lucy. 2º.- Homo habilis (skillful man) hominid species, should adopt a more upright position because climatic variations grew grasslands and forced to stand on their feet to spot potential hazards. They had a larger brain, about 750 cubic centimeters. Its most important feature was the change in how power: not only ate fruits and vegetables but also animals. From hairy body. Currently researchers disagree about whether homo habilis hunted intentionally and manufactured tools to do so. It is believed they could have spoken. Fossils were found in the Olduvai Gorge (Tanzania) with the first utensils. Age: 2 million years 3º.- Homo erectus (upright man) also called Pithecanthropus Erectus. Some saw it as the direct representative of man, but now known to many previous austratopithecus had similar traits. They are the first hominids were widely distributed over the surface of the planet, reaching the Southeast and East Asia. Body deep, thick eyebrows and big muscles. They had a greater than that of homo habilis brain: about 1,100 cubic centimeters. They discovered the use of fire and produced the first hand ax. The first homo erectus was found in Java (Oceania) late last century. The discovery of hominid remains of this species in caves Beijing allowed the reconstruction of some aspects of his life. Age: 1.5 million years 4º.-Homo sapiens (wise man) lived in Europe, Africa and Asia. Archaeological findings reflect important changes in the behavior of this species: use of stone tools and worked bone, changes in the forms of hunting, use and control of fire, use of dress, increase in the size of populations, ritual manifestations and artistic. The representative of homo sapiens is the oldest Neanderthal (Germany). Age: from 150,000 to 200,000 years 5º.-Homo sapiens sapiens (modern man) Their physical characteristics are the same as those of modern man. His brain capacity is around 1,400 cubic centimeters. It is believed that appeared in Europe around 40,000 years ago. Homo sapiens sapiens is the starred, from 10,000 BC, major changes in economic and social organization, as the earliest forms of agriculture and domestication of animals, and life in cities. His most faithful representative is Cro-Magnon man (France) .Antigüedad: From 35,000 to 40,000 years. I espoero clarified the issue ..... sorry Invictus.
