Maria Concepcion Soto settled in the northern area of Venezuela. She suffered from a rare genetic disorder called Huntington’s Disease. As a result, the now 20,000 individuals who live there also have a high risk of Huntington’s Disease. This is an example of_

Genetic Diversity is increased through this process.

When looking for mates, female bower birds prefer males who decorate their nests with a little extra blue, be it plastic or feathers.

A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?

If you have a dramatic change resulting in a new species in between long stretches of time with no change this would be

Coevolution is the

If an animal evolves to be more camouflaged in an environment, and another animal evolves a better ability to sense movement. This would be

Forming of a new species by evolution from pre-existing species.

Slow changes over a long period of time.

What type of evolution is described in the following scenario:Porcupines in the United States have quills (spines) that are attached to their skins. When they feel threatened, they can tense up their bodies, causing the quills to “shoot out.” These spiny quills can pierce the skin of attacking animals, causing injury and pain. Although not closely related to the porcupine, hedgehogs that live throughout parts of Europe also have protective spines that they use to defend themselves from attacking animals.

What type of evolution is described in the following scenario: King Snakes are a family of snakes that usually eat other snakes in the wild. Even though many of the snakes they eat are very poisonous, King Snakes have adapted the ability to not be affected by their poisons. In response, some of these poisonous snakes, like rattlesnakes, have adapted other defensive behaviors (other than biting) to try and “scare off” the King Snakes.

What type of evolution is described in the following scenario: The flowers that bloom from the saguaro cactus have evolved a bright, white coloration to attract many of the bats they rely on to pollinate their flowers. Since they rely on the bats, they have also adapted to opening their flowers at night, when the bats are active. The bats have also adapted to the cactus by a.) developing the ability to hover above the flowers, and b.) developing a long tongue that can reach deep inside the flower.

What type of evolution is described in the following scenario: Chameleons, a type of lizard (reptile), have two eyes they can move in completely different directions, so they can see all the way around themselves. Sand lances are a type of fish that can also move their eyes like the chameleon, even though they are not related to one another.

What type of evolution is described in the following scenario: A kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.

What type of evolution is described in the following scenario: In the ocean surrounding Antarctica, there are fish that survive the cold water by using a molecule made of glycoproteins that circulates the blood and keeps it from freezing. Certain kinds of worms that live in the Arctic ocean also make antifreeze proteins that help them live in icy water

What type of evolution is described in the following scenario: Bees don’t see red, but do see yellow, blue, and ultra-violet light. Thus, bee-pollinated flowers are mostly yellow or blue with UV nectar guides (landing patterns) to guide the bee.
