In this paper, it is argued that selection and drift might be distinct. This contradicts recent arguments by Brandon (forthcoming) and Matthen and Ariew (2002) that such a distinction “violates sound ...
Natural Selection as a Population-Level Causal Process
natural selection evolution, causation

Recent discussions in the philosophy of biology have brought into question some fundamental assumptions regarding evolutionary processes, natural selection in particular. Some authors argue that natur...
Multi-Level Selection and the Major Transitions in Evolution

A number of recent biologists have used multi-level selection theory to help explain the major transitions in evolution. I argue that in doing so, they have shifted from a ‘synchronic’ to a ‘diachroni...

One controversy about the existence of so called evolutionary forces such as natural selection and random genetic drift concerns the sense in which such "forces" can be said to interact. In this paper...

Biologists and philosophers have been extremely pessimistic about the possibility of demonstrating random drift in nature, particularly when it comes to distinguishing random drift from natural select...
Two strong arguments have been given in favour of the claim that no selection process whatever can play a role in explaining adaptations. According to the first one, selection is a negative force; it ...
Adaptive speciation: The role of natural selection in mechanisms of geographic and non-geographic speciation
Speciation mechanisms Isolating mechanisms

Recent discussion of mechanism has suggested new approaches to several issues in the philosophy of science, including theory structure, causal explanation, and reductionism. Here, I apply what I take ...
Mathematical physicist Lee Smolin has proposed a theory of Cosmological natural selection which, he argues, explains the existence of our life-supporting universe, and which, he claims, is superior to...
