Evolution Review

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

What is a change in an organism that allows for it to survive in its environment?

• homologous
• vestigial
• variation
• adaptation

The hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigial structures

On the Galapagos islands, Charles Darwin observed:

• completely unrelated birds on each of the islands
• birds exactly like those found in south america
• somewhat similar birds, with different beaks for different foods
• birds completely unrelated to those found in south america

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

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

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Fish, reptiles, and mammals each have gill slits during part of their embryological development. Which statement best explains this observation?

• Their embryos all swam in the sea.

• They each evolved one from the other.

• They do not excrete gases during their development.

• They all had a common ancestor.

Bones in this diagram are examples of...

• homologous structures
• vestigial organs
• DNA evidence

What happens when the adaptations of a species are not enough to survive in a changed environment?

• The species goes extinct

• The population increases

• mutations occur

• variation occurs

Dolphins have the same arm structure as wolfs, what type of evidence for evolution does this represent?

• DNA
• vestigial structures
• homologous structures
• embryology
