Evolution Open Notes Quiz

Organisms with traits that make them more likely to have a high number of offspring will contribute more of their genes to the next generation's gene pool. What is this called?

• Acquired Characteristics

• Endosymbiotic Theory

• Natural Selection

• Artificial Selection

When two populations can not breed because they are active at different times of the day, they are said to be...

• Behaviorally Isolated

• Temporally Isolated

• Gametically Isolated

• Geographically Isolated

In Endosymbiotic Theory, why do we suspect that Mitochondria and Chloroplasts were once their own free-living bacteria?

• They are small

• They have their own DNA

• They die when we take antibiotics

• Sometimes they become infectious

Scientists give every organisms a unique two-part name. What is this practice called?

• Binomial Nomenclature

• Taxonomy

• Classification

• Cladistics

A population of rabbits is being hunted by hawks. The hawks prefer the larger rabbits. The smaller rabbits have an easier time hiding. Therefore, the population gets smaller and smaller every generation. What kind of natural selection is this?

• Artificial Selection

• Disruptive Selection

• Stabilizing Selection

• Directional Selection

Which level of classification has the greatest variety of different organisms?

• Kingdom

• Phylum

• Class

• Order

In some species "goose bumps" are a helpful adaptation. But in humans they are no longer useful. What is the term for these types of traits?

• Fit

• Acquired

• Vestigial

• Homologous

The bones of a bat's wing and the bones of a human's arm have the same structure and pattern. What do we call structures that are similar due to shared ancestry?

• Vestigial

• Homologous

• Analogous

• Expeditious
