What distinguishes erectus from ergaster?
erectus, which somewhat obscures the differences between the two. There are subtle, potentially significant, differences between the East African and East Asian fossils. Among these are the somewhat higher-domed and thinner-walled skulls of H. ergaster, and the even more massive brow ridges and faces of Asian H.
What makes Homo erectus so different from earlier forms of man?
Early H. erectus had smaller, more primitive teeth, a smaller overall size and thinner, less robust skulls compared to later specimens. The species also had a large face compared to modern humans. Like Neanderthals, their skull was long and low, rather than rounded like our own, and their lower jaw lacked a chin.

What did the Homo ergaster do?
These Dmanisi fossils are significant because they currently represent the earliest evidence for the emergence of early humans from Africa into Eurasia 1.75 million years ago. The size and shape suggest that they were made by Homo ergaster, which also makes them the oldest surviving footprints made by a human species.
What was the first tool made by man?
The Early Stone Age began with the most basic stone implements made by early humans. These Oldowan toolkits include hammerstones, stone cores, and sharp stone flakes. By about 1.76 million years ago, early humans began to make Acheulean handaxes and other large cutting tools.
What is the oldest human ancestor?
anamensis is the oldest unequivocal hominin, with some fossils dating from as far back as 4.2 million years ago. For years it has occupied a key position in the family tree as the lineal ancestor of Australopithecus afarensis, which is widely viewed as the ancestor of our own genus, Homo.
Who found Peking Man?
John Gunnar Andersson
Peking Man discovered In 1921, Swedish geologist John Gunnar Andersson was visiting Zhoukoudian, 55km south-west of Beijing. He was taken by a local resident to see a cave full of ‘dragon bones’.
Which one is known as Peking Man?
Homo erectus pekinensis
Peking Man (sometimes now called Beijing Man), also called Sinanthropus pekinensis (currently Homo erectus pekinensis), is an example of Homo erectus. The remains were first discovered in 1923-27 during excavations at Zhoukoudian (Choukoutien) near Beijing (Peking), China.
When did humans first make tools?
2.6 million years ago
The earliest stone toolmaking developed by at least 2.6 million years ago. The Early Stone Age began with the most basic stone implements made by early humans.
Where did Homo ergaster and Homo erectus come from?
Homo Ergaster & Homo Erectus. There were later discoveries in China (Peking Man) beginning in the 1920s. Generally considered to have been the first species to have expanded beyond Africa, Homo erectus is a highly variable species, spread over two continents (it’s not certain whether it reached Europe).
What’s the difference between H.erectus and h.ergaster?
This long-running debate remains unresolved, with researchers typically using the terms H. erectus s.s. ( sensu stricto) to refer to H. erectus fossils in Asia and the term H. erectus s.l. ( sensu lato) to refer to fossils of other species that may or may not be included in H. erectus, such as H. ergaster, H. antecessor and H. heidelbergensis.
How tall was Homo ergaster and how much did he weigh?
Homo Ergaster & Homo Erectus. H. ergaster had a cranial capacity (700-900cm³ in earlier ergaster specimens, and 900-1100 in later specimens). It is estimated that H. ergaster stood between 4 ft 9 inches (145 cm) and 6 ft 2 inches ( 185 cm) tall. Their weight ranged from 88 – 150 lbs (40 – 68 kg).
Are there any fossils that are the same as Homo erectus?
Caucasus. These findings suggest that previous fossil finds that were classified as different species on the basis of the large morphological variation among them—including Homo rudolfensis, Homo gautengensis, H. ergaster, and potentially even H. habilis —should perhaps be re-classified to the same lineage as Homo erectus.
