Alongside the hand-ax tradition there developed a distinct and very different stone tool industry , based on flakes of stone: In Europe the Clactonian industry is one example of a flake tradition. The early flake industries probably contributed to the development of the Middle Paleolithic flake tools of the Mousterian industry , which is associated with the remains of Neanderthals.

In Taforalt, Morocco , the beads were dated to approximately 82, years ago, and other, younger examples were encountered in Blombos Cave, Blombosfontein Nature Reserve, on the southern coast of South Africa. Experts determined that the patterns of wear seem to indicate that some of these shells were suspended, some were engraved, and examples from both sites were covered with red ochre. Replica stone tools of the Acheulean industry, used by Homo erectus and early modern humans, and of the Mousterian industry, used by Neanderthals.

The invaders, commonly referred to as the Cro-Magnons , left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler , cave paintings and Venus figurines. These tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40, cal BP. Some of them may have been occupied year round, though more commonly they appear to have been used seasonally; people moved between the sites to exploit different food sources at different times of the year.

Burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in this period, along with the fish hook , the oil lamp , rope , and the eyed needle. The changes in human behavior have been attributed to changes in climate, encompassing a number of global temperature drops.

These led to a worsening of the already bitter cold of the last glacial period popularly but incorrectly called the last ice age. Such changes may have reduced the supply of usable timber and forced people to look at other materials.

In addition, flint becomes brittle at low temperatures and may not have functioned as a tool. Oldowan The earliest documented stone tools have been found in eastern Africa, manufacturers unknown, at the 3. The tools were formed by knocking pieces off a river pebble, or stones like it, with a hammerstone to obtain large and small pieces with one or more sharp edges. The original stone is called a core; the resultant pieces, flakes.

Typically, but not necessarily, small pieces are detached from a larger piece, in which case the larger piece may be called the core and the smaller pieces the flakes. The prevalent usage, however, is to call all the results flakes, which can be confusing.

A split in half is called bipolar flaking. Consequently, the method is often called "core-and-flake". More recently, the tradition has been called "small flake" since the flakes were small compared to subsequent Acheulean tools. Various refinements in the shape have been called choppers, discoids, polyhedrons, subspheroid, etc. To date no reasons for the variants have been ascertained: However, they would not have been manufactured for no purpose: The whole point of their utility is that each is a "sharp-edged rock" in locations where nature has not provided any.

There is additional evidence that Oldowan, or Mode 1, tools were utilized in "percussion technology"; that is, they were designed to be gripped at the blunt end and strike something with the edge, from which use they were given the name of choppers. Modern science has been able to detect mammalian blood cells on Mode 1 tools at Sterkfontein , Member 5 East, in South Africa. As the blood must have come from a fresh kill, the tool users are likely to have done the killing and used the tools for butchering.

Plant residues bonded to the silicon of some tools confirm the use to chop plants. They cannot be said to have developed these tools or to have contributed the tradition to technology. They continued a tradition of yet unknown origin. As chimpanzees sometimes naturally use percussion to extract or prepare food in the wild, and may use either unmodified stones or stones that they have split, creating an Oldowan tool, the tradition may well be far older than its current record.

According to the current evidence which may change at any time Mode 1 tools are documented from about 2.

Meanwhile, living contemporaneously in the same regions H. Mode 1 was now being shared by a number of Hominans over the same ranges, presumably subsisting in different niches, but the archaeology is not precise enough to say which. Oldowan out of Africa Tools of the Oldowan tradition first came to archaeological attention in Europe, where, being intrusive and not well defined, compared to the Acheulean, they were puzzling to archaeologists.

The mystery would be elucidated by African archaeology at Olduvai, but meanwhile, in the early 20th century, the term "Pre-Acheulean" came into use in climatology. P, Brooks, a British climatologist working in the United States, used the term to describe a "chalky boulder clay" underlying a layer of gravel at Hoxne , central England, where Acheulean tools had been found.

Hugo Obermaier , a contemporary German archaeologist working in Spain, quipped: Unfortunately, the stage of human industry which corresponds to these deposits cannot be positively identified.

All we can say is that it is pre-Acheulean. This uncertainty was clarified by the subsequent excavations at Olduvai; nevertheless, the term is still in use for pre-Acheulean contexts, mainly across Eurasia, that are yet unspecified or uncertain but with the understanding that they are or will turn out to be pebble-tool.

One strong piece of evidence prevents the conclusion that only H. If the date is correct, either another Hominan preceded H. After the initial appearance at Gona in Ethiopia at 2. The manufacturers had already left pebble tools at Yiron , Israel, at 2.

Erectus was found also at Dmanisi , Georgia, from 1. Pebble tools are found the latest first in southern Europe and then in northern. They begin in the open areas of Italy and Spain, the earliest dated to 1.

The mountains of Italy are rising at a rapid rate in the framework of geologic time; at 1. Europe was otherwise mountainous and covered over with dense forest, a formidable terrain for warm-weather savanna dwellers. Similarly there is no evidence that the Mediterranean was passable at Gibraltar or anywhere else to H. They might have reached Italy and Spain along the coasts. In northern Europe pebble tools are found earliest at Happisburgh , United Kingdom, from 0.

The last traces are from Kent's Cavern , dated 0. By that time H. In the late 19th and early 20th centuries archaeologists worked on the assumptions that a succession of Hominans and cultures prevailed, that one replaced another. Today the presence of multiple hominans living contemporaneously near each other for long periods is accepted as proved true; moreover, by the time the previously assumed "earliest" culture arrived in northern Europe, the rest of Africa and Eurasia had progressed to the Middle and Upper Palaeolithic, so that across the earth all three were for a time contemporaneous.

Both portray women in full voluptuous beauty. Beginning approximately kya, the large cutting tools of the Achuelian are gradually displaced by Levallois prepared core technologies, also widely used by Neanderthals during the European Middle Palaeolithic. The development of new, regionally relevant tools, such as those used for the collection of marine resources seen at Abdur , Ethiopia, Pinnacle Point Cave, South Africa, and Blombos Cave , South Africa.
