Part 2 : adaptation to meet ecological challenges. Instead of purpose many biologist use the word function . This system recruits thinking and reasoning areas of the brain. In the subjects gambling for sure gains - or possible losses described above, not all subjects stuck with the sure gains option. Maladaptive traits: reduce fitness are likely to be prominent in a changing environment, where new ecological challenges or opportunities cgange the fitness consequences of pre-existing character. Maladaptive traits can be maintained by tradeoffs and constraints. Nothing in the action of natural selection prevents traits from multitasking.
