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

Which statement best describes the process of evolution?

• Populations can survive in different locations on earth
• Environmental conditions limit the number of species on Earth
• Populations grow when resources are abundant
• The traits of a species can change over time

Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes

Which is NOT a factor of  Natural Selection?

• variation
• competition
• mutation
• acquired characteristics

All of these finches have different shaped beaks, they are an adaptation to gain access of 

• Water
• Food
• Shelter

This scientist developed the theory of evolution as he studied the finches.

• Charles Darwin
• Isaac Newton
• Albert Einstein
• Marie Curie

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation
• Adaptation
• Behavior
• Environment
