From Ethiopia comes the news of the discovery of bones of giant - a giant for the era in which he lived.
Archaeologists have published the research conducted on the remains of a male specimen of Australopithecus afarensis with a height of 1.52 m, 40cm higher than the famous Lucy, too 'it belongs to the same species. The fossil was named appropriately Kadanuumuu, which in the Afar language means "great man".
The finding was unearthed in 2005 in the region of AF (ETOP), is dated at 3.58 million years. This age is between Ardipithecus (4.4 Ma), considered one of the oldest hominids known so far, but whose evolutionary relationship to the genus Australopithecus is unclear, and Lucy, younger than 400,000 years. The fossil
Kadanuumuu thanks to the preservation of many bones postcraniali so far missing in the reconstruction of Australopithechi reconfirmed biomechanical and anatomical studies conducted previously on other fossils of Australopithecus. The genre could walk upright on two feet in an effective and very similar to modern man already 3.6 million years ago. The new fossil also shows an evolution of the proportions of the chest and lower limbs in A. africanus .
Limb lengthening is an adaptation to walk fast and powerful, it is confirmed that these adjustments, along with others for walking biped characters are very old.
