What Darwin Never Knew

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

What was the name of the ship that Charles Darwin sailed in?

• HMS BEAGLE
• SS LEXINGTON
• HMS BEETLE
• LA SANTA MARIA

what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands
• all species on one of the islands
• identical species on all the islands
• the same species as North America

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

The more genetic variation  a population has,
 the more likely it will _____

• evolve
• migrate
• survive
• mutate

The gradual development of a species into a new one to survive.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection
