Vignettes of Famous Evolutionary Biologists, Large and Small

From Robert Trivers. Here is Trivers on William Hamilton:

Certainly one of the most creative minds I have ever met in biology. I still remember the day a graduate student came running down the hall saying “Have you heard Hamilton thinks that bacteria use clouds for dispersal? As quick as you can say “Bill Hamilton”, I asked “Has he shown how the bacteria get the rain to fall where they want it to?” And indeed his idea humbled me because ever since I had been coming to Jamaica I had heard rural people tell me “trees draw rain” as in, don’t cut them down, and I had thought to myself you poor benighted souls, you have the correlation right but causality wrong—naturally, where it rains more, trees are more apt to grow. Now Bill suggested they Jamaicans may well have had it right all along—lower temperatures over wooded areas could itself be a useful signal.
