In evolutionary biology, reciprocal altruism is a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism's fitness, with the expectation that the other organism will act in a similar manner at a later time.. The genotype that an individual possesses for a trait, in turn, determines the phenotype the observable characteristicssuch as whether that individual actually ends up with straight, wavy, or curly hair. Lorem ipsum, amet, consectetur adipiscing elit. But if the malesor the preferences of the femaleswere to change, the species are still closely enough related that they could probably still mate successfully. Were the solution steps not detailed enough? We can learn a lot from these instances of fast speciation, says Cornell Lab scientist Leonardo Campagna, who has studied these finches for 10 years.
