Orrorin tugenensis is considered to be the second-oldest (after Sahelanthropus) known hominin ancestor that is possibly related to modern humans, and it is the only species classified in genus Orrorin. Orrorin is significant because it can be an early bipedal hominin.

Discovery of Strange Ancient Human Bedfellow Sheds Light on Genetic Diversity

The first genomes sequences of Neanderthals and Denisovans revealed that these groups interbred with anatomically modern humans more than 30,000 years ago. But now more complete versions of the Denisovan and Neanderthal genomes reveal another notch in the belt of our ancient ancestors. The Denisovan interbred with an unknown 'archaic ancestor' in Asia.

Lucy. Australopitheque ossements datant de 3.2 M années, découverts en 1974 en Ethiopie par les chercheurs qui écoutaient "Lucy in the sky with diamonds"...

Orrorin tugenensis (Millenium man) is considered to be the second-oldest (after Sahelanthropus) known hominin ancestor that is possibly related to modern humans, and it is the only species classified in genus Orrorin. Orrorin is significant because it can be an early bipedal hominin. The age of the specimen have been estimated to 6 to 5.8 million years.

El Braquiosaurio fué un dinosaurio emparentado con el Ultrasauros por que al igual que el tiene las extremidades delanteras más grandes que las delanteras esto les permite erguir su cuello, midió 30m de largo y 15 de alto pesaba aproximadamente 70 toneladas.

Orrorin tugenensis is considered to be the second-oldest known hominin ancestor that is possibly related to modern humans. The fossils are estimated to date between 6.2 and 5.6 million years ago. The fossils come from at least five individuals. There are proofs that Orrorin walked upright and bipedally; data was suggestive of tree-climbing skills. The small teeth size suggest that Orrorin ate mostly fruit and vegetables, with occasional meat. Orrorin was about the size of a modern…

This Face Changes the Human Story. But How?

Homo naledi, discovered in a cave near Johannesburg, is a human ancestor unlike any species previously known. The find is arguably one of the most important discoveries in human origins research in half a century. It’s also the most perplexing.
