David’s penultimate post on Sewall Wright, Notes on Sewall Wright: The Shifting Balance Theory – Part 1:
Two catch-phrases indissolubly linked with Sewall Wright are the adaptive landscape, and the shifting balance. In preparing my note on Wright’s concept of the adaptive landscape I was surprised to discover that Wright himself seldom if ever used this expression. I could not find a single example. I was therefore half-expecting that I would not find any reference to the shifting balance either – and I would have been half-right. Wright did use that term, but not, as far as I can find, until surprisingly late in his long career….
Part 2 coming soon….
