Concept of fitness; natural selection
Abstract:
Fitness is the central concept in evolutionary theory. It measures a phenotype’s
ability to survive and reproduce. There are different ways to represent this measure:
Malthusian fitness and Wrightian fitness. One can go back and forth
between the two, but when we characterize model properties or interpret data,
it can be important to distinguish between them. Here, we discuss a recent
experiment to show how the interpretation changes if an alternative definition
is used.
