Document Summary
Darwins chain of logic exponentially if all individuals reproduce available resources there must be a struggle for existence . Observation: all species have the capacity to increase population size. Observation: population size is usually maintained within reasonable limits. Inference: since more individuals are produces than can be supported by the. Inference: as a consequence only a proportion of the total offspring will live to. Inference: given variation observable in every population and the heritability fo that variation, those that are most suited to the environment will have a greater chance of surviving in the struggle for existence. The characteristics of these individuals will be passes on to the next generation through reproduction reproduce. There are 2 different peppered moth morphs. Traditionally, the population has both morphs, but the dark morph is rare. Light morph is harder for predators to see on lichen covered birch bark trees.
