Some Biogeographers, Evolutionists and Ecologists:
Wynne-Edwards was one of the century's leading behavioral ecologists. The key element of his point of view was his elucidation of the hypothesis of group selection, an idea which, though frequently discussed, continues to attract only limited acceptance among evolutionary biologists. Early in his career Wynne-Edwards worked especially on fishes and birds, concurrently developing an interest in marine biology. In one of the more creative research projects he was able to get the Cunard Line to let him make a number of free voyages across the North Atlantic in their ships to examine the changing movements and migration patterns of seabirds. A resulting report, published in 1935, won him a Walker Prize from the Boston Natural History Society. During his tenure at McGill he concentrated on studies of freshwater fishes and far-northern plants and birds; these efforts later won him another Walker Prize. On returning to Britain he made use of his earlier investigations into the breeding behavior and population structure of birds by developing the group selection idea, which posed that populations, rather than individuals, are the focus of selective forces; specifically, it is those populations that develop means of exploiting their resources sustainably that will tend to succeed at the expense of those who are less successful at doing so. This thinking was spelled out in full in 1962 in one of the century's leading ecology titles, Animal Dispersion in Relation to Social Behaviour.
