- The earliest known fossil of a human ancestor, a female Ardipithecus ramidus specimen nicknamed Ardi, is 3.2 million years old. Scientific evidence says that the first modern humans, Homo sapiens, appeared more than 200,000 years ago. Some fossils from the middle Pleistocene period (about 400,000 years ago), referred to as Homo sapiens rhodesiensis, may be archaic Homo sapiens - a transitional species.

When did humans appear on earth? There are many more ancestors going back to when humans and apes diverged from their common ancestor 14 million years ago. Figuring out the exact relationships is a fascinating puzzle that will be around for a long time to come.

The History of Human Migration Scientific consensus puts the earliest known ancestors of modern humans in East Africa, roughly 200,000 years ago. The first wave of humans to migrate out of Africa about 85,000 years ago followed the coasts through the Middle East, into Southern Asia via Sri Lanka, and eventually around Indonesia and into Australia.

Who am I? Who were the first humans? Scientists agree that our early ancestors, Homo erectus, first appeared in Africa 1–2 million years ago. They spread throughout the world and evolved into ancient humans. Most believe that modern humans evolved in Africa, and gradually replaced all the other ancient humans (the 'Out-of-Africa' theory). Some scientists believe that ancient humans may have evolved into modern humans all over the world at around the same time (the 'multiregional' theory). Either way, by about 30,000 years ago, we – Homo sapiens – were the only humans left on the planet.

When did modern humans first appear on earth? All the evidence that has been collected suggests that there was no individual first human. Humans gradually differentiated from their ancestors. The oldest remains of anato … mically modern humans are about 200 thousand years old and were found in east Africa.

- MELONITE, and its synonymous trade-name, Tufftride (or Tenifer) , is a relatively straight-forward, flexible process to operate and maintain, and produces exceptionally uniform case hardening.he MELONITE process begins with the placement of parts in a re-circulating air preheat furnace, followed by immersion for 60-240 minutes in a molten nitrogen-rich salt solution contained in an aerated furnace.

Did first humans emerge from Middle East, not Africa? Other scientists have argued that human beings originated in Africa before moving to other regions 150,000 to 200,000 years ago. Homo sapiens discovered in Middle Awash, Ethiopia, from 160,000 years ago were believed to be the oldest 'modern' human beings. Other remains previously found in Israeli caves are thought to have been more recent and 80,000 to 100,000 years old.

Human evolution Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago. They entered Europe somewhat later, between 1.5 million and 1 million years. Species of modern humans populated many parts of the world much later. For instance, people first came to Australia probably within the past 60,000 years and to the Americas within the past 30,000 years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12,000 years.

Early human migrations Early human migrations. Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both anatomically modern humans and Neanderthals.

- The first fossils of early modern humans to be identified were found in 1868 at the 27,000-23,000 year old Cro-Magnon rock shelter site near the village of Les Eyzies in southwestern France. They were subsequently named the Cro-Magnon people. They were very similar in appearance to modern Europeans.t would be a mistake to assume that from the time modern Homo sapiens began migrating out of Africa that all people in that continent were modern humans. The video below presents evidence of pockets of archaic humans surviving in West Africa until at least 13,000 years ago.

Human evolution Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.

How Many People Have Ever Lived on Earth? Fixing a time when the human race actually came into existence is not a straightforward matter. Various ancestors of Homo sapiens seem to have appeared at least as early as 700,000 B.C. Hominids walked the Earth as early as several million years ago. According to the United Nations Determinants and Consequences of Population Trends, modern Homo sapiens may have appeared about 50,000 B.C. This long period of 50,000 years holds the key to the question of how many people have ever been born.

The oldest Homo sapiens Media Contacts. Feb. 16, 2005 – When the bones of two early humans were found in 1967 near Kibish, Ethiopia, they were thought to be 130,000 years old. A few years ago, researchers found 154,000- to 160,000-year-old human bones at Herto, Ethiopia.Now, a new study of the 1967 fossil site indicates the earliest known members of our species, Homo sapiens, roamed Africa about 195,000 years ago.hese rock beds likely were deposited by annual flooding on the ancient Omo River. Beds below those shown here yielded the oldest fossils of humans (Homo sapiens) ever found. They date to 195,000 years ago.

When did the first human appear on earth? Sahelanthropus is the name of the first human on earth, one of our earliest human ancestors, may have swung down from a tree in Africa and started to walk upright. He had a smaller brain than we do, a flatter face and a heavy eyebrow ridge.

Earliest Evidence Of Modern Humans Detected After decades of debate, paleoanthropologists now agree the genetic and fossil evidence suggests that the modern human species -- Homo sapiens -- evolved in Africa between 100,000 and 200,000 years ago. Yet, archaeological sites during that time period are rare in Africa.

Sahelanthropus tchadensis When Lived: Sometime between 7 and 6 million years ago. Sahelanthropus tchadensis is one of the oldest known species in the human family tree. This species lived sometime between 7 and 6 million years ago in West-Central Africa (Chad). Walking upright may have helped this species survive in diverse habitats, including forests and grasslands.

- modern Homo sapiens. The first fossils of early modern humans to be identified were found in 1868 at the 27,000-23,000 year old Cro-Magnon rock shelter site near the village of Les Eyzies in southwestern France. They were subsequently named the Cro-Magnon people. They were very similar in appearance to modern Europeans. Males were 5 feet 4 inches to 6 feet tall (1.6-1.8 m.) That was 4-12 inches (10-31 cm.) taller than Neandertals. Their skeletons and musculature generally were less massive than the Neandertals.

Human evolution The earliest fossils of anatomically modern humans are from the Middle Paleolithic, about 200,000 years ago such as the Omo remains of Ethiopia; later fossils from Es Skhul cave in Israel and Southern Europe begin around 90,000 years ago (0.09 million years ago).n other words, H. floresiensis shares a common ancestor with modern humans, but split from the modern human lineage and followed a distinct evolutionary path. The main find was a skeleton believed to be a woman of about 30 years of age. Found in 2003, it has been dated to approximately 18,000 years old.

Oldest Human Fossil Discovered In Ethiopia For decades scientists have been scouring Africa for ancient human remains. Archaeologists think Homo habilis, the first truly “human-like” primate, lived about 2.5 million years ago, and Lucy, the human-ape mashup who is perhaps our most famous ancestor, lived about 3.2 million years ago.

- Flash slideshow: The first Homo sapiens. The skulls, dug up near a village called Herto, fill a major gap in the human fossil record, an era at the dawn of modern humans when the facial features and brain cases we recognize today as human first appeared.he fossil evidence, said Asfaw, clearly shows what molecular anthropologists have been saying for a long time-that modern Homo sapiens evolved out of Africa. These fossilized skulls from Herto show that modern humans were living at around 160,000 years ago with full-fledged Homo sapiens features.
