Exercise 13

In 2008, the New York Times published an article, "New Fossil Analysis Finds Species Walked Upright 6 Million Years Ago," that summarized a recent research article regarding human evolution. In this article, the information presented challenges the previously accepted hypotheses on (1) when human ancestors began to walk upright and (2) who might be our closest relatives. Do you think these findings invalidate other scientific findings? Explain your position.
