Physical anthropologists have just discovered something new about early humans. Humans before us were a good deal bigger in size than we are today. From the findings of human fossils in Spain and in China researchers have found that humans before us had thicker, longer, and broader pelvises in both males and females. Scientists believe this was probably due to the way their conditions made them the way they were. In order to live where they did they had to adapt to the colder climate.
