Evolution of total net fitness in thermal lines: Drosophila subobscura likes it 'warm'.

Abstract excerpt

Fisher's fundamental theorem states that heritable variation for net fitness sets a limit to the rate of response to natural selection. How will temperate (i.e. cold-tolerant) species cope with contemporary rapid global warming? Using three-fold replicated lines of Drosophila subobscura that had been allowed to evolve for 4 years (between 32 and 59 generations) at 13 degrees C (cold), 18 degrees C (the supposed...
