Document Summary
Breeders scrutinize their flocks and select the individuals with the most desirable traits. When they reproduce, the next generation consisting of the progeny of only the selected birds, will show the desirable traits in a higher proportion than existed in last year"s flock. The individuals with the most favorable variations, those who are better at surviving and reproducing, are naturally selected. * darwinian evolution: gradual change in populations over time. As a result, the characteristics of the population will change slightly with each succeeding generation. Darwinian fitness is the ability of an individual to survive and reproduce in its environment. Adaptation a trait or characteristic of an organism, like a modified form of reverse transcriptase, the increases its fitness relative to individuals without the trait. 3. 3 the evolution of flower color in an experimental snapdragon population. * bumblebees could influence the evolution of a floral trait controlled by alleles of a single gene. Postulate 1: there is variation among individual.
