Top ten works in the Theory of Evolution

I would suggest adding Theodosius Dobzhansky's Genetics and the Origin of Species (1937, Columbia Uni Press) to your list. Another is Ernst Mayr's Animal Species and Evolution, (1963, Belknap/Harvard Uni Press).I guess everybody has their favorites. For ecology, obviously the Wilson/MacArthur book you mentioned is one of the most influential, putting the science on a sound theoretical footing for the first time. For modern conservation theory, Wilson's Biodiversity, (1988, National Academy Press), is among the most influential.What is interesting is that - while considering your OP - I started to think about which books were the most personally influential in launching me in my chosen career. I know that this isn't directly related to the OP, but the most influential I came up with was an early childhood gift of Rachel Carson's Silent Spring, (1962, Houghton-Mifflin), which I read around age 10 or so. Amazing what early exposure to science can do for someone.
