Homo rudolfensis is an extinct species of archaic human from the Early Pleistocene of East Africa about 2 million years ago (mya). Because H. rudolfensis coexisted with several other hominins, it is debated what specimens can be confidently assigned to this species beyond the …

2024年1月3日 · Was Homo rudolfensis on the evolutionary lineage that evolved into later species of Homo and even perhaps our species, Homo sapiens? Are Homo rudolfensis and Homo habilis indeed different species, or are they part of a single, variable species? Or …

2023年4月25日 · Homo rudolfensis is an early human species that lived in East Africa between c. 2.5 and 1.8 million years ago. It is known from a handful of skull, jaw and teeth fragments that remind alternatingly...

The scientific name Homo rudolfensis was originally proposed for the specimen skull KNM-ER 1470, discovered in 1972. It was once thought by many to be a member of the species Homo habilis but the differences compared to other Homo habilis skulls were considered too great.

H. rudolfensis is named for the fossil KNM-ER 1470, found on the east side of Lake Rudolf (now Lake Turkana) in Kenya. KNM-ER 1470 most clearly exemplifies H. rudolfensis and is characterized by a large cranial capacity (around 750 cc), large cheek teeth, and a long face that is broad across the orbits (eye sockets) and flattened below the nose.

The second species of Early Homo to be discovered is now known as Homo rudolfensis, since it was discovered at the site of Koobi Fora on the east side of Lake Turkana, which was formerly known as Lake Rudolf. Homo rudolfensis may be a descendent of Kenyanthropus platyops.

…collection of fossils attributed to H. rudolfensis, the Uraha Hill jawbone takes its place in the centre of intense debate on the origin of the human genus. It is the earliest member attributed to H. rudolfensis, but precise dates are difficult to establish. Some experts prefer to include all the…

2012年8月8日 · The two species are the oldest members of the genus Homo. H. habilis lived roughly 2.4 million to 1.4 million years ago while H. rudolfensis lived about 2 million years ago. But where some...

There are two type specimens for the Homo rudolfensis species. Fossils of this genus/species were first found in 1972, near Omo river and Koobi Fora, Lake Turkana in Kenya.

The Homo rudolfensis cranium KNM-ER 1470 was discovered by B. Ngeneo in 1972 at Koobi Fora in Kenya and described by R. Leakey in Nature in 1973. The classification of this specimen has been a matter of debate since its discovery, with some scientists arguing in favor of Australopithecus, and some in favor of a species of Homo.
