What was Fisher's fundamental theorem of natural selection and what was it for?
Fisher's 'fundamental theorem of natural selection' is notoriously abstract, and, no less notoriously, many take it to be false. In this paper, I explicate the theorem, examine the role that it played in Fisher's general project for biology, and analyze why it was so very fundamental for Fisher. I defend and Lessard (1997) in the view that the theorem is in fact a true theorem if, as Fisher cla...

متن کاملThe ancestral human diet: what was it and should it be a paradigm for contemporary nutrition?
Awareness of the ancestral human diet might advance traditional nutrition science. The human genome has hardly changed since the emergence of behaviourally-modern humans in East Africa 100-50 x 10(3) years ago; genetically, man remains adapted for the foods consumed then. The best available estimates suggest that those ancestors obtained about 35% of their dietary energy from fats, 35% from car...
متن کاملReaction rate theory: what it was, where is it today, and where is it going?
A brief history is presented, outlining the development of rate theory during the past century. Starting from Arrhenius [Z. Phys. Chem. 4, 226 (1889)], we follow especially the formulation of transition state theory by Wigner [Z. Phys. Chem. Abt. B 19, 203 (1932)] and Eyring [J. Chem. Phys. 3, 107 (1935)]. Transition state theory (TST) made it possible to obtain quick estimates for reaction rat...
