Evolution/Taxonomy Review

Fossils help scientists:

• Measure the amount of carbon dioxide

• Determine what life was like in the past

• Predict what future life forms will look like

• Refute Darwin's Theory of Natural Selection

What is evolution?

• The rate at which a species reproduces

• The change in traits in a species over successive generations

• The change in Earth's climate over the past 500 million years

• The loss of an entire species due to disease or natural disaster

According to Darwin's Theory of Natural Selection, favorable traits are known as:

• Adaptations

• Mutations

• Learned Traits

• Instincts

According to Darwin's Theory of Natural Selection, organisms with favorable traits are:

• more fit and more likely to survive

• more fit and less likely to survive

• less fit and more likely to survive

• less fit and less likely to survive

Match the following Mechanisms of Evolution

• Organisms most fit for environment survive and reproduce better than others in a population.

• Gene Flow

• Mates select their mate based on certain criteria.

• Non-Random Mating

• Results from a drastic decrease in the population size, leaving only those genes present remaining.

• Genetic Drift

• Migration of organisms into a new population or out of a population, changing the gene pool of each

• Mutations

• Introduces new genes into the gene pool through random changes in genetic material

• Natural Selection

Match the following Mechanisms of Evolution

• Giraffes with longer necks can reach more leaves. This was a random change in DNA that was passed on

• Mutations

• Every winter, birds fly south to warm climates, and intermate with other populations of birds

• Genetic Drift

• In peacocks, males have pretty feathers to attract mates. Prettier males are more likely to mate.

• Non-Random Mating

• A group of birds are blown away from the mainland. The birds establish new population on island.

• Natural Selection

• In the rainforest, frogs with bright colors are less likely to be eaten. # of bright frogs increases

• Gene Flow
