The second word in this species’ scientific name is erectus. This name was selected to indicate that this species’ ability to stand and walk with an upright or erect stance.

Homo erectus is now one of the better known of our human relatives with over 40 specimens excavated from Java and many more from sites in China.

Sangiran on the island of Java, is the most important Homo erectus site in Indonesia. The remains of over 80 individuals have been found here at a number of localities. The region was first occupied about 1.6 million years ago.

The site of Zhoukoudian, 40 kilometres south of Beijing in China, has yielded the largest number of Homo erectus fossils from any one locality (about 50 individuals are represented by the remains). About 100,000 stone tool artefacts were also in the cave. These were mostly quartz and sandstone chopping tools and flakes. It was occupied between 200,000 and 750,000 years ago, although evidence suggests that occupation was sporadic rather than permanent. Hyenas and other animals also used the cave site.

Initial excavations between 1926 and 1937 yielded five skullcaps, various other skull fragments, 11 jaws and more than 140 teeth. Almost all of these fossils were lost in 1941 when the Japanese invaded China during World War II. Fortunately, accurate replicas of these fossils had been made. Additional Homo erectus fossils were excavated at Zhoukoudian after World War II and have also been excavated since from Chinese sites including Hexian, Lantian and Nanjing.

A growing number of scientists have redefined the species Homo erectus so that it now contains only east Asian fossils. Many of the older African fossils formerly known as Homo erectus have now been placed into a separate species, Homo ergaster and this species is considered to be ancestral to Homo erectus. The redefined Homo erectus is now generally believed to be a side branch on our family tree whereas Homo ergaster is now viewed as one of our direct ancestors.

However, some scientists still support the view that all these specimens are Homo erectus and that this species includes individuals that vary in their features and have a widespread distribution over both time and geographic location.

There is even debate about whether the two Asian H.erectuspopulations represent the same species. Prior to the 1950s the fossils from Java were known as Pithecanthropus erectus and those from China were called Sinanthropus pekinensis.

Even if the populations in Indonesia and China were the same species, the idea is now being proposed that the populations were not connected, and that the Chinese population arrived later than the Indonesian and came from a different source. Initially, it was believed that the Asian H.erectus originated with one group that dispersed from a single source in Africa.

This species had a robust skeleton that was generally similar to those of modern humans. However, the skulls of Homo erectus were quite different to those of modern humans.

The oldest known stone tools used by Homo erectus were made in China about one million years ago. These tools were simple choppers and flakes (Mode 1 technology).

Tools gradually became smaller over time and came to include a greater variety of designs. More complex bifacial tools (Mode 2 technology) like those made by Homo heidelbergensis people from Eurasia made a limited appearance in parts of northern China. This may indicate a brief period of contact between these different peoples.

Relatively few stone tools have been found in east Asia compared with western Asia, Africa and Europe but tools made from non-durable materials such as bamboo may have been manufactured instead.

China underwent significant climatic changes during the period that Zhoukoudian was occupied. These changes included three cold glacial periods with harsh, winter temperatures. The cooling and drying that occurred in these glacial periods brought an expansion of open habitats, with grasslands and mixed steppes. These environments favoured large grazing animals, which would have been hunted by Homo erectus.

Java, on the other hand, had a warmer climate. Low sea levels about 1.6 million years ago (when this area was first occupied by H.erectus) may have seen Indonesia joined to mainland southeast Asia.

The remains of meals have been found at some Homo erectus sites in China. These show that they ate large amounts of meat supplemented with plant foods and, in general, had a diet similar to that of early modern humans.

About two million years ago, a new set of fossils began to appear in the human fossil record. Designated as Homo erectus, they show evidence of increases in both body size and brain size.

Homo erectus is arguably the earliest species in the human lineage to have so many human-like qualities. Earlier hominins had important similarities with living humans, like bipedality, and H. erectus still had a long evolutionary path to become like you and me, but the fossils assigned to H. erectus display a number of new and distinctly modern human traits.

Homo erectus is often referred to as the first cosmopolitan hominin lineage, meaning the first hominin species whose geographic range had expanded beyond a single continental region. While fossil remains from H. erectus are found in Africa, like those of earlier hominins, they have also been identified at fossil sites widely dispersed across Eurasi

There are a number of fascinating evolutionary questions that can be asked of H. erectus. The species was not only geographically widespread, it also had a long temporal span in the hominin fossil record (Antón 2003). With its earliest appearance in the fossil record from localities in the Lake Turkana Basin, Kenya, sometime around two million years ago

Fossils of these short and stocky humans, with their distinctive skull shape and large brow ridges, have mostly been found in China and Indonesia.

Debate abounds as to whether the Asian fossils and those from Africa should be classified together as Homo erectus or if the African examples are different enough to be called Homo ergaster.

The information on this page refers specifically to Asian Homo erectus.
