Researchers are studying 3 species of anteaters with small, medium, and long snouts that live on an isolated island. Termite populations that burrow underground are a favorite food for the anteaters. Over time, most of the pig population is made up of individuals that have very long snouts. This is an example of which type of selection?

When individuals with an average form of a trait have the highest fitness, the result is

What is speciation?

A horse and a donkey can successfully mate to produce offspring known as a mule. Mules are sterile (they cannot reproduce offspring) . Would mules be classified as a species?

A population in genetic equilibrium means that

Mutations that improve an individual's ability to survive and reproduce are

When two populations no longer interbreed what is the result?

The incorrect theory that inheritance of traits, like the giraffes long neck, can be acquired through practice and use, was proposed by

The book Darwin published after analyzing his data he collected from his 5 year voyage on the HMS Beagle shook the scientific and religious world. It was called

Which of the two models are correct in Darwin's interpretation of the Theory of Evolution?

Scientists have always felt that the genes we have been born with influence who we are and are passed onto our offspring. However, new research suggests other factors, such as what we eat, can influence our gene expression. This is called

Is there an advantage of being heterozygous for the sickle cell anemia trait?

When human beings rather than nature select which traits to breed, we call this

A special breed of bunnies found in the wild all throughout England are found to have offspring that have fur and another type that are born fur-less. Those bunnies born without fur will die within a couple of weeks from the cold temperatures in the English countryside. If the allele combination for bunnies with fur is (FF) and (Ff) allele and the combination for fur-less bunnies is (ff) make a prediction as to what will happen to the f allele in the bunny population after 100 generations of mating.

The peppered moth changed from ___________ to ____________ during England's Industrial Revolution. This is a great example of _____________ _____________ caused by a genetic______________

Let's say we are breeding bunnies. We know that brown fur is dominant and is caused by the allele (B). White fur in the same bunny population is caused by the allele (f). Out of 100 bunnies we noticed 60 have white fur. What is the percentage of bunnies that have white fur?

2,500 years ago on a small island, individuals in a population of seed eating birds had a wide variety of beak sizes. After many generations, ALL of the birds have medium beaks, with small and large size beaks absent. If the number of birds with each beak size was graphed which example would it look like? (Graphs A, B, C looking left to right)

Let's analyze what is going on in the graphic illustration. In the initial population of lizards we can observe a lizard population with 3 variations of skin color. What statement best describes what probably happened to this population by Generation 30? Please select ALL possible correct answers.

These 3 different species of orchids grow just feet away from each in a forest other but are completely different species. The mechanism that causes this phenomenon is called

Based on our understanding of bunnies being born wild in cold northern England, what allele combination is usually fatal?

A measure of how commonly a particular allele occurs in a population is known as the

Darwin collected fossils from various countries that were millions of years old but looked similar to animals that were walking the earth today. He stated that this was evidence that they all came from a common ancestor. He called these fossils

Structures that are remnants of an organisms evolutionary past but seem to have no function, such as the "pelvic bones" in a whale are called
