EVOLUTION by Natural Selection

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 were the beaks on Darwin's finches so Important?

• They showed the finches always existed as Darwin found them.

• They showed that the finches could mutate their beaks whenever they want.

• They showed variability in the finches species. All finches were equally adaptable to all islands.

• They show that the finches adapted to their environments. Their beak shape matched the food available on each island.

What most likely caused the finches on the Galapagos Islands to have beaks that were differnt from the finches living on the South American mainland?

• They were different types of food available on the island.
• The finches on the islands had to drink salt water.
• There were different types of predators living on the island.
• The finches on the mainland built different types of nests.

What is it called when an organism is best adapted to its environment, it will survive and reproduce more successfully than other organisms less adapted?

• evolution of all species
• natural selection
• selective breeding

The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.
