On their own, the fossils will not tell us much, says palaeontologist Tim White of the University of California, Berkeley, “So little of the anatomy is preserved that these fossils do not teach us much new about chimpanzee anatomical evolution.” But, the finding does suggest that chimp ancestors were more capable of adapting to a broader range environments than previously thought. The earliest ancestor of modern-day chimpanzees is the hominoids or apes. A possible fourth tooth is still awaiting analysis. They were found in sediments that include fossils of two early humans – Homo erectus or Homo rhodensiensis – suggesting that chimp and human ancestors were contemporaries.
