Organic evolution, a text book
Lull, Richard Swann
'Many of these pulsations have been described in the foregoing pages, and in each instance we have attempted to define the physical change which served to accelerate the flow of life. And in almost every successful attempt we have found the immediate influence to be one of climate.' - Organic Evolution, Lull, 1927.
Probably a bit like war can cause a pulsation of human culture. Not always good for current denizens, but someone or some-species will survive in prominence.
