They were also the first humans to use fire, a technology that has been passed down through the ages. Archaeologists have discovered stone tools dating back to the Stone Age as far back as 25,000 years. Knives, spear points, and hand axes are most commonly used by hunters, while meat cleavers and scrapers are used by cleaners to remove animal hides. Other methods of removing animal skins included digging for roots, peeling bark, and removing the animal’s skin. The first evidence of this is the discovery of stone tools in Africa, dated to about 2.6 million years ago. Homo erectus likely used a variety of tools, including sharpened stones, spears, and perhaps even fire.
Ergaster; or, 2) it is in fact an Asian species or subspecies distinct from African H. Ergaster that would later undergo back-migration to Africa, where it would evolve eventually into modern homo sapiens. If crania are ruled out from belonging to Homo erectus essentially because of a large cranial capacity, then of course one will end up with a ‘species’ of only small-brained individuals. Scrapers are one of the original stone tools, found everywhere where people settled, long before the Neolithic Age began.

Erectus in Africa invented Mode II tools, indicating they used both Mode I and Mode II technologies concurrently over hundreds of thousands of years. The gold mine where the artifacts were found is just one of what mining experts have called a new “gold rush” in Sudan. According to the country’s ministry of natural resources, Sudan produced 93 tons of gold in 2018, which ranks it third on the list of gold-producing nations, after South Africa and Ghana. The discoveries at Gona dispel this notion, showing that both types of tool were used at the same time.
The circled tools are of the same type but with the tools on the right, being made by H. While the tools on the left were constructed by H. Homo sapiens took many of the innovations of the Neanderthals and improved on them, specializing the stone tools into smaller more complex, refined tools.
Could Homo Erectus Have Been a Trading Species?
Miners in northeastern Sudan discovered the trove of hominid artefacts. They include almond-shaped cleavers and hand axes with a transverse cutting edge. That’s what happened in 2020 in Sudan, in the Sahara Desert.
To reconstruct the area’s vegetation, researchers used carbon isotopes from soil samples. The tools may have been used to open nuts, tubers, and dead logs, according to a study. Of no surprise to scientists were the so-called Acheulian tools, which include the classic pear-shaped hand axe used by Homo erectus across the globe. These Acheulian tools — often symmetrical, well-shaped and sharpened on two edges — replaced earlier Oldowan tools, which were much simpler, sharp-edged stone flakes. This is where things go off the rails, since both skulls were found close to both tool types.

Homo ergaster is considered the innovator of the Acheulean stone tool industry which consisted of the creation of large cutting tools like hand axes and cleavers. Increased reliance on a broader set of tools may have helped Homo erectus survive during changing climates. The early Stone Age saw the development of the first stone tools by Homo habilis, one of the earliest members of the human family. These were basically stone cores with flakes removed from them to create a sharpened edge that could be used for cutting, chopping or scraping. The image to the left represent replicas of the stone tools used by Homo erectus and early modern H.
The purpose of these was to make a sharper edge for cutting, chopping, or scraping by removing flakes from stone cores. From about 2.4 million years ago until about 1.4 million years ago, Homo erectus was the most common human ancestor in Africa. Around 1.8 million years ago, Homo erectus began to make and use stone tools, which allowed them to hunt for food more effectively. It is thought that the use of stone tools by Homo erectus was instrumental in their success as a species.
Erectus was able to both create — and identify — the right tool for the job. Adding these two crania to the 48 crania above (using the mean value of 850 cc for BSN12/P1 cranium), the mean cranial capacity of 50 Homo erectus crania is about 926 cc. Hence, it may be validly asked why the cranial capacities of all Homo erectus crania are below the modern human mean, some being considerably below. Early Stone Age Tools The earliest stone toolmaking developed by at least 2.6 million years ago. The image to the left represents stone tools of early H.
The Homo erectus may have been the first to use stone tools, but it is possible that they would have started using them in large numbers if he had not. This stone age tools shake-up started with the discovery of multiple skull fragments in Ethiopia dating back 1.26 and 1.5 million years, respectively. However, while some small-brained Homo erectus specimens can possibly be explained as a result of pathology, there are too many specimens with small cranial capacity for pathology to be an explanation for all of them. And even if some may have been pathological, it is more likely that they were, for example, pathological Homo erectus-type humans, not pathological anatomically modern humans. For reasons unknown many members of this group had small brain size, and hence small cranial capacity. In 2012 and 2013, scientists found two-sided hand axes and other carefully shaped bone and stone tools in Konso, Ethiopia and near Lake Turkana in Kenya, all of which dated to an astonishing 1.75 million years in the past.
It dispels the idea that each hominin species used just one type of tool technology and indicates that H. Erectus was more behaviourally flexible than we thought. Homo erectus was the first human species, and it was extinct for more than 30,000 years.
The other skull was larger and sturdier with big brow ridges, and probably male, implying large physical differences between the sexes. Archaeology has never seen people develop creative minds and self-esteem during this time period. The famous cave paintings from this period depicted animals, hunting groups, and stories told in magnificent cave paintings.
