Symbolic Life of Neandertals

At least seventeen sites in Europe, South Africa, and Southwest Asia include Middle Paleolithic burials. • Shanidar Cave, Iraq • Kebara Cave, Israel

physical traits of Neandertals

Extremely muscular people - Their large noses and teeth projected forward. - They had bony brow ridges over their eyes. - On the back of their skull, there was a bunlike bony mass for attachment of powerful neck muscles

Language Gene

FOXP2 gene found on chromosome 7 was identified through the analysis of a family in which members have severe language problems. • Identification of this gene allows researchers to compare its structure to that found in other mammalian species. • FOXP2 in apes differ from that found in humans.

Homo erectus in Western Europe

Fossil evidence indicates the presence of the genus Homo on the Eurasian landmass at 1.8 mya., In western Europe, fossil evidence starts at 1.2 mya., Sierra de Atapuerca region in Spain, and nearby Grand Dolina have yielded fragments of four individuals.

Homo erectus in Indonesia

Fossils found in Java reach about 40 individuals., There was a long continuity of H. erectus fossils in Southeast Asia from about 500,000-700,000 years ago., In the past lower sea levels resulted in a continuous landmass between most of Indonesia and the Asian continent.

Homo habilis

Found in East Africa and in South Africa. From the neck down, the skeleton of Homo habilis differs little from Australopithecus. Earliest representative of the genus Homo-the human line.

tripling

In the 1950s, the _______________ and similar specimens from Indonesia and China were assigned to the species Homo erectus because they were more human than apelike

"Pit of the Bones" (Sima de los Huesos)

In the Sierra de Atapuerca in northern Spain, between 205,000 and 325,000 years ago, the remains of 28 individuals of both sexes, were dumped into a deep cave shaft known today as......

Oldowan Tools

Microscopic wear patterns show that these flakes were used for cutting meat, reeds, sedges, and grasses and for cutting and scraping wood. Small indentations on their surfaces suggest the leftover cores were transformed into choppers, for breaking open bones, and they may have been used to defend the user.

Homo heidelbergensis

Named for the Mauer jaw, this name is now used as a designation for all European fossils from about 500,000 years ago until the appearance of the Neandertals.

physical traits of Neandertals

Occipital bun (large projection at the back of the skull) • Supraorbital torus (browridge) • Low forehead • Mid-facial prognathism • Barrel-shaped rib cage and robust limbs suggest cold climate adaptation

Language Origins

Oldowan toolmakers, like modern humans, were overwhelmingly right-handed. In making tools, they gripped the core in the left hand, striking flakes off with the right

Speech and Language in the Middle Paleolithic

Paleoneurologists working from endocranial casts agreed that Neandertals had the neural development necessary for spoken language. - The size of the hypoglossal canal in Neandertals is like that of modern humans and unlike that of apes. - An expanded thoracic vertebral canal suggests the increased breath control required for speech.

tertiary scavengers

earliest member of the genus homo, They were third in line to get something from a carcass after a lion or leopard managed to kill.-By the time H. habilis could get near the carcass of a dead animal, only bones remained. -They used tools to break open the long bones to get at the rich marrow inside. (The storing of stone tools, and raw materials for making tools, attests to their ability to plan ahead.)

genus homo

human line

Mousterian and Aurignacian Traditions

Population expansion into previously uninhabited colder regions was made possible through cultural adaptations to a colder climate. • Energy rich animal fat in the diets of cold climate meat eaters provides hunters with the extra energy needed for hunting and keeping the body warm. An abundance of associated animal bones showing cut marks include wild cattle, horses, mammoths, and woolly rhinoceroses. • Neandertals were not opportunistic hunters, rather organized. • Some Mousterian sites contain evidence of long production sequences, reshaping, and discarding of tools.

Acheulean Tool Tradition

The tool-making tradition of Homo erectus in Africa, Europe, and Southwest Asia in which hand-axes were developed from the earlier Oldowan chopper., The earliest hand-axes, from East Africa are about 1.6 million years old., Those found in Europe are no older than about 500,000 years.

Homo antecessor

This name was coined by splitters for the earliest Homo fossils from western Europe discovered in Spain; antecessor is Latin for "explorer" or "pioneer."

biped

The femur, or thighbone, was human in shape, and its proportions indicated the homo erectus was a

The Discovery of Homo erectus

The flat skull, with its low forehead and enormous brow ridges, appeared to be like that of an ape; but it possessed a cranial capacity much larger than an ape's, though small by modern human standards.

The Genus Homo

a comprised of a group of various species that are characterized by increased brain size compared to earlier species and appeared around 2.5 mya in the fossil record.

One of the first Neandertals

was found in a cave in the Neander Valley near Düsseldorf, Germany, in 1856— before scientific theories to account for human evolution had gained acceptance. Examination of the fossil skull, a few ribs, and limb bones revealed that the individual was a human being, but it did not look "normal." • Evidence indicates Neandertals were nowhere near as brutish and apelike as originally portrayed. • Some scholars now see them as the archaic H. sapiens of Europe and Southwest Asia, ancestral to the more derived, anatomically modern populations of Europe and Southwest Asia of the last 30,000 years.
