Homo erectusHomo erectus (ˌhoʊmoʊ_ə'rɛktəs; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Its specimens are among the first recognizable members of the genus Homo. Several human species, such as H. heidelbergensis and H. antecessor, appear to have evolved from H. erectus, and Neanderthals, Denisovans, and modern humans are in turn generally considered to have evolved from H. heidelbergensis. H.
Lake TurkanaLake Turkana (tɜːrˈkɑːnə,_-ˈkæn-) formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van (passing the shrinking South Aral Sea), and among all lakes it ranks 24th.
Homo ergasterHomo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene. Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology. Proponents of synonymisation typically designate H. ergaster as "African Homo erectus" or "Homo erectus ergaster". The name Homo ergaster roughly translates to "working man", a reference to the more advanced tools used by the species in comparison to those of their ancestors.
HumanHumans, or modern humans (Homo sapiens), are the most common and widespread species of primate. A great ape characterized by their hairlessness, bipedalism, and high intelligence, humans have a large brain and resulting cognitive skills that enable them to thrive in varied environments and develop complex societies and civilizations. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states.
Peking ManPeking Man (Homo erectus pekinensis) is a subspecies of H. erectus which inhabited the Zhoukoudian cave site in modern northern China during the Chibanian. The first fossil, a tooth, was discovered in 1921, and the Zhoukoudian Cave has since then become the most productive H. erectus site in the world. Peking Man was instrumental in the foundation of Chinese anthropology, and fostered an important dialogue between Western and Eastern science for decades to come.
AcheuleanAcheulean (əˈʃuːliən; also Acheulian and Mode II), from the French acheuléen after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with Homo erectus and derived species such as Homo heidelbergensis. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with Homo erectus remains.
Human evolutionHuman evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes all the great apes. This process involved the gradual development of traits such as human bipedalism, dexterity and complex language, as well as interbreeding with other hominins (a tribe of the African hominid subfamily), indicating that human evolution was not linear but weblike.
KenyaKenya, officially the Republic of Kenya (Jamhuri ya Kenya), is a country in East Africa. With a population of more than 47.6 million in the 2019 census, Kenya is the 28th most populous country in the world and 7th most populous in Africa. Kenya's capital and largest city is Nairobi, while its oldest and second largest city, which until 1907 was also Kenya's first capital city, is the coastal city of Mombasa which includes Mombasa Island in the Indian Ocean and the surrounding mainland.
PaleolithicThe Paleolithic or Palaeolithic (ˌpeɪl-,_ˌpæliəʊˈlɪθɪk), also called the Old Stone Age (from Greek: παλαιός palaios, "old" and λίθος lithos, "stone"), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 cal BP.
