7. The impact of automobile and airplane travel (throughout the 1900's)

These developments gave people the ability to move freely and quickly around the planet. Their importance to anthropology lies in their roles in helping end the long-lasting, isolating barriers between human populations. Prior to the 1900's, travel by people was slow, relatively dangerous, and only involved a small number of individuals. The enormous numbers of human beings who moved during the 1900's, sometimes over substantial distances, ended any isolation among human beings. This development will result in the not too distant future in the disappearance of human population difference. Human beings are becoming a homogeneous species.

 

Alan E. Mann is a Professor of Anthropology at the University of Pennsylvania. His Top 10 list reviews the 1900's in a general historical light and shows how the major events affected the work and chief concerns of anthropologists. He generally calls attention to broad movements rather than single momentous events. He points to the rapid population growth during the 1900's and reveals why some anthropologists link this trend to the end of human evolution.
