EVOLUTION UNDER WAY  ~7 million years

Sahelanthropus tchadensis is a fossil hominid that lived approximately 7 million years ago. Its position in the Hominid evolution is not widely accepted.

Existing fossils – a relatively small cranium nicknamed Toumaï ("hope of life" in the local Dazaga language of Chad), five pieces of jaw and some teeth – make up a head that has a mixture of derived and primitive features. The braincase, being only 340 cm³ to 360 cm³ in volume is similar to that of extant chimpanzees and is notably less than the approximate human volume of 1350 cm³. The teeth, brow ridges, and facial structure differ markedly from those found in Homo sapiens.(click to see all the article on Wikipedia)

演化依舊進行中 ~7百萬年前

查德沙赫人是一個只有化石的猿人,存在於約7百萬年前。其在猿人進化歷程當中,還沒有廣泛地被認同。

存在的化石-一個相對較小的頭骨,被稱為圖邁(查德當地的Dazaga語中謂之生命的希望”),有五片下頜碎片及一些牙齒-組成了一個頭部,混合著原始與衍生出來的特徵。腦腔的容積只有340360立方公分,近似於現存的黑猩猩,明顯小於人類的1350立方公分。其牙齒,眉骨和面部結構都與智人有明顯的分別。
