Evolution by Natural Selection

According to the theory of evolution by natural selection what is changing over time?

• The inherited traits of a population.

• Characteristics of individual organisms.

• The strength of a population.

• Attractive features.

Why are advantageous traits more likely to be passed onto offspring?

• Because those that have them are more likely to reproduce.

• Because they are stronger traits.

• Because they are more dominant traits.

• Because they are acquired traits.

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

These moths are all the same species. The differences between their wings is an example of ________________

• Acquired Characteristics

• Genetic Variation

• Homeostasis

• Over-reproduction

Which is not an example of an adaptation?

• A bird's beak allows it to crack open hard nuts.
• A peacock's tail attracts a mate.

• A frog's large hind legs allow it to jump from danger.
• A squirrel learns to raid garbage cans for food scraps.

English natural scientist who formulated a theory of evolution by natural selection (1809-1882) after being inspired by his journey aboard The Beagle.

• Darwin

• Wallace

• Linnaeus

• Lamarck

The finches on the Galapagos island were similar in form except for variations of their beaks. Darwin observed that these variations were useful for:

•  attracting a mate
•  defending territory
•  building nests
•  gathering food
