Evolution

Who was the first naturalist to study evolution?

• Charles Darwin
• Gregor Mendal
• Carolus Linneaus
• Thomas Edison

This is a process by which organisms inherited advantageous traits that tend to reproduce more successfully than the other organisms do. 

• Artificial selection
• Natural selection
• Populations
• Environment

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.
