The Evolution of Early Man

Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism — the ability to walk on two legs — evolved over 4 million years ago. Other important human characteristics — such as a large and complex brain, the ability to make and use tools, and the capacity for language — developed more recently. Many advanced traits — including complex symbolic expression, art, and elaborate cultural diversity — emerged mainly during the past , years. Physical and genetic similarities show that the modern human species , Homo sapiens, has a very close relationship to another group of primate species, the apes. 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.

The Hobbit who helped us find our origins 21 Feb “Yet we know that these individuals came from the same location and the same geological time, so they could, in principle, represent a single population of a single species,” he said. The researchers compared the variation in characteristics of the skulls and found that while their jaw, brow and skull shapes were distinct, their traits were all within the range of what could be expected among members of the same species.

It also suggests that early members of the modern man’s genus Homo, first found in Africa, soon expanded into Asia despite their small brain size. It backs up what we found as well,” said Milford Wolpoff, a paleoanthropologist at the University of Michigan. We don’t have different subspecies. But it is normal for humans to vary, and they have varied in the past.

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.

Bock Coeloglossum Hartm. The genus has leafy stems carrying oblong to elliptic leaves and blooms on a terminal, racemose, subdensely few to many flowered inflorescence with leaf-like bracts and carries small, green, flowers with sessile ovaries. The ovate dorsal sepal, obliquely ovate lateral sepals and the linear petals carry a short spurred, deflexed, wedge-shaped to oblong, 3 toothed lip with a short column and short, orbicular staminodes, a triangular hooded rostellum, caudate pollina and 2 remote viscidium and an orbicular-triangular to reniform stigma.

A stunningly well-preserved skull from 1. With a tiny brain about a third the size of a modern human’s, protruding brows and jutting jaws like an ape, the skull was found in the remains of a medieval hilltop city in Dmanisi, Georgia, said the study in the journal Science. It is one of five early human skulls — four of which have jaws — found so far at the site, about kilometers 62 miles from the capital Tbilisi, along with stone tools that hint at butchery and the bones of big, saber-toothed cats.

A stunningly well-preserved skull from million years ago offers new evidence that early man was a single species with a vast array of different looks, researchers said. With a tiny brain about a third the size of a modern human’s, protruding brows and jutting jaws like an ape, the skull was.

Scientists say they have discovered a new species of human relative in South Africa"Homo naledi” appears to have buried its dead — a behavior previously though limited to humans The discovery could transform our understanding of human evolution Rising Star Cave, South Africa CNN When an amateur caver and university geologist arrived at Lee Berger’s house one night in late with a fragment of a fossil jawbone in hand, they broke out the beers and called National Geographic.

Berger, a professor at the University of the Witwatersrand in Johannesburg, South Africa, had unearthed some major finds before. But he knew he had something big on his hands. What he didn’t know at the time is that it would shake up our understanding of the progress of human evolution and even pose new questions about our identity. Two years after they were tipped off by cavers plumbing the depths of the limestone tunnels in the Rising Star Cave outside Johannesburg, Berger and his team have discovered what they say is a new addition to our family tree.

The team is calling this new species of human relative"Homo naledi,” and they say it appears to have buried its dead — a behavior scientists previously thought was limited to humans. Read More Berger’s team came up with the startling theory just days after reaching the place where the fossils — consisting of infants, children, adults and elderly individuals — were found, in a previously isolated chamber within the cave.

The team believes that the chamber, located 30 meters underground in the Cradle of Humanity world heritage site, was a burial ground — and that Homo naledi could have used fire to light the way.

Homo erectus is an extinct species of early human that lived throughout the Pleistocene from about million years to most recently, , years ago. The study of the fossil, discovered by scientists proved that Homo erectus originated in Africa and spread through India, China, Georgia, and Java.

Before Darwin[ edit ] The word homo, the name of the biological genus to which humans belong, is Latin for “human”. It was chosen originally by Carl Linnaeus in his classification system. The word “human” is from the Latin humanus, the adjectival form of homo. Darwin[ edit[ edit ]ossibility of linking humans with earlier apes by descent became clear only after with the publication of Charles Darwin ‘s On the Origin of Species , in which he argued for the idea of the evolution of new species from earlier ones.

Darwin’s book did not address the question of human evolution, saying only that “Light will be thrown on the origin of man and his history. Huxley argued for human evolution from apes by illustrating many of the similarities and differences between humans and apes, and did so particularly in his book Evidence as to Man’s Place in Nature. However, many of Darwin’s early supporters such as Alfred Russel Wallace and Charles Lyell did not initially agree that the origin of the mental capacities and the moral sensibilities of humans could be explained by natural selection , though this later changed.

Darwin applied the theory of evolution and sexual selection to humans when he published The Descent of Man in

Skull discovery suggests early man was single species

Introduction Hominid or hominin? Some scientists use a broader definition of Hominidae which includes the great apes, and instead call the group I am discussing “hominins”. The word “hominid” in this website refers to members of the family of humans, Hominidae, which consists of all species on our side of the last common ancestor of humans and living apes. Hominids are included in the superfamily of all apes, the Hominoidea, the members of which are called hominoids.

Wolpoff and Adam Van Arsdale of Wellesley College published a study in the journal Evolution last year that also measured statistical variation in characteristics of early skull fossils in Georgia and East Africa, suggesting a single species and an active process of inter-breeding.

We don’t have different subspecies. But it is normal for humans to vary, and they have varied in the past. The name also retracts the unique species status of Homo georgicus given to the jaw that was found in along with other small, primitive skulls. The jaw lay a few yards meters from where Skull 5, belonging to the same owner, was later discovered in Co-author Marcia Ponce de Leon of the University of Zurich said Skull 5 was “perfectly preserved” and “the most complete skull of an adult fossil Homo individual found to date.

With other partial remains previously found at the rural site, it gives researchers the earliest evidence of human ancestors moving out of Africa and spreading north to the rest of the world, according to a study published Thursday in the journal Science.
