Darwin, Natural Selection and Evidence of Evolution

What accurately describes Charles Darwin's profession?

• a naturalist
• a medical doctor
• a chemist
• a physicist

In different parts of the world, Darwin found unrelated species that looked alike because

• the species lived in different environments
• the species lived in similar environments
• the species were closely related
• the species once lived in the same place

According to Lyell, how are geographical features formed? 

• Slowly, forces such as erosion have accumulated over time
• They appeared in a matter of hours
• They appeared in a matter of a few years 
• Differently than they were created in the past

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.

This scientist stated that by using or not using a certain body part, organisms could change in their lifetime and that the trait gained would be passed down to their offspring.

• James Hutton
• Charles Lyell
• Jean-Baptiste Lamarck
• Thomas Malthus

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
