Which of the following is the best example of the evolution of an adaptation? a. Non-random survival and reproduction favors finches with broader beaks, increasing the bill size in the next generation. b. A predator eats snails with a striped shell at a higher rate than other snails. By chance the pink snails in the population have a low rate of striping. In the next generation, more pink-shelled snails are present. c. A population of sticklebacks in a lake have low levels of armor. Migrants from the ocean introduce genes for increased armor to the population. d. Female bowerbirds choose to mate with males that have the bowers most elaborately decorated with blue objects. Overtime the bowers become increasingly complex. e. All of the above are examples of adaptive evolution.

Answer:a. Non-random survival and reproduction favors finches with broader beaks, increasing the bill size in the next generation.

Explanation:

Each species will develop or evolve a trait that will allow them to survive better and better as time goes by.

Theiry trait keep improving so that they can compete better and efficiently.

These beaks may be the adaption that is needed in order to obtain food efficiently and effectively.

It will improve their survival as they evolve and develop this improved beaks.
