Cooperation has been a more important evolutionary jorce in the development of man than has the bitter competitive struggle for existence. So asserted a learned U.S. biologist last week in an attack on those who use the doctrine of evolution to justify totalitarian brutality and aggression. The attacker was Zoologist Alfred Edwards Emerson of the University of Chicago; his audience was the holiday meeting-in Dallas-of the American Association for the Advancement of Science...
These two baby giant pandas (escorted by Zoologist John Tee-Van,) arrived safely in San Francisco last week after a hazardous journey by plane from Chungking to Manila, by ship from Manila to Hawaii, through the sub marine-infested Pacific in the first convoy to reach the West Coast since the Japanese attack.

In a new, barless $15,000 home at New York City's Bronx...
...colonies draft their soldier armies and maintain balance in their incredible caste systems was cleared up last week by a Chicago zoologist. The secret: a "social hormone" exuded by some of the ants to inhibit the others...

When it appeared in Britain, Cott was at once snapped up by the British armed forces to make their guns as inconspicuous as woodcocks, their tanks as bush bucks, their planes as pickerel. Sternly scientific, the book is more readable than popular "wonder books" of nature...
