How do we measure the fitness of animals?
Fitness is at the core of evolutionary theory, but Darwinist
claim that it is difficult to measure accurately.
They say that it is difficult to measure the long-term
fitness of animals, but they did it due to twenty years of precise field observations of a
wild passerine bird population
These researchers used their study to come to grips
with fitness.
But they could not find the answer. Natural selection that
Darwin used in evolution did not give the results they wanted.
