What does Darwin's theory of evolution suggest?

• species change over time
• extinct species are not related to living species
• different species can interbreed
• animals that look alike are most closely related

The name of Darwin's first publication was

• Inheritance of Acquired Traits
• Human Evolution
• On the Origin of Species
• My Voyage on the Beagle

The idea that acquired characteristics are passed to later generations was developed by...

• Darwin
• Aristotle
• Lamarck
• Buffon

In what major way did Darwin's ideas diverge from Lamarck's?

• Lamarck thought changes to an individual animal during its lifetime would be passed on to offspring

• Lamarck believed that environmental pressures drive evolution

• Lamarck thought that animals would not have had time to evolve in Earth's short history

• Lamarck did not believe that species could change over time

NGSS.HS-LS4-2

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.
