The upshot is that most philosophers of biology now hold that biological properties supervene on physical properties (where supervenience is taken to include some kind of "in virtue of" relation), and that fitness and other biological properties are not identical… — Elliott Sober Copy Share Image
Trait X is fitter than trait Y in a population of organisms if those organisms have other biological traits T and live in an environment that has properties E. The theory of natural selection is filled with statements of this… — Elliott Sober Copy Share Image
From the fact that E is evidence for T and the fact that T entails M, it doesn't follow that E is evidence for… — Elliott Sober Copy Share Image
Evolutionary game theory was originally developed as an alternative to the hypothesis of group selection; now it is clear that game theory models postulate… — Elliott Sober Copy Share Image
Earlier attempts to show that simpler theories always have higher prior probabilities have failed, but there is a restricted circumstance in which the claim… — Elliott Sober Copy Share Image
"Methodological naturalism" and "metaphysical naturalism" are terms that often surface in the continuing battle between evolutionary biology and creationism/intelligent design. The methodological thesis says… — Elliott Sober Copy Share Image
The big picture, I think, is that common ancestry is evidentially prior to natural selection in Darwin's theory and in contemporary evolutionary biology as… — Elliott Sober Copy Share Image
This is not to deny that there are versions of theism that do conflict with evolutionary biology. Young Earth Creationism is an example; it… — Elliott Sober Copy Share Image
Some philosophical arguments (e.g., in connection with the mind/body problem) look pretty good, while others (e.g., those that criticize moral realism) do not. — Elliott Sober Copy Share Image
I have spent a lot of time arguing that the theory of group selection is not the stupid, pernicious doctrine that many biologists once… — Elliott Sober Copy Share Image
Group selection and individual selection are just two of the selection processes that have played important roles in evolution. There also is selection within… — Elliott Sober Copy Share Image
Instead of thinking of the question of race genealogically, and leaving it open whether vernacular races are genealogical units, the interest in biomedicine has… — Elliott Sober Copy Share Image
