two color variations: bright blue and bluish-gray.

Bright blue coloration is a recessive condition that is rare in the original population (less than 5% of the birds have the trait). A small flock of 5 wrens is blown by a storm onto a new island that is 100 miles away from their old home. 3 of the 5 birds were blue-gray and the other 2 were bright blue.

This new population thrives on the island as it is the only bird species present on an island with lots of food and no predators to hunt them. Over the next 10 years, the 5 birds and their descendants reproduce and populate the island, creating a population that is made up of about 40% bright blue wrens.

later, a hawk species is blown over to the island. This hawk hunts the smaller wrens using its excellent vision. The bluish-gray birds blend in better with the landscape compared to the bright blue birds.

Name the specific mechanism of microevolution that the wren scenario displays when they were first blown over to the new island. (word bank: artificial selection, gene flow, genetic drift, mutation, natural selection, random mating, Hardy-Weinberg equilibrium, sexual selection)

Prior to the introduction of the predator on the island, would you expect the wren population grow forever (yes or no)?

After introduction of the predator on the island, we would expect the coloration of the wren to _. (word bank: stay the same, shift toward bluish-gray, shift toward bright blue, be a blending of the two phenotypes)
