Question

Read the sentences below. (2 points)

Charles Darwin studied various species on his voyage around the world. On the Galapagos Islands, he noticed that the beak size and shape varied for the finches he found from island to island.





Select ONE option from each of the three sections below to complete a claim about the scenario above.

Part A - Claim
What claim did Darwin make about the finches of the Galapagos Islands had a variety of shapes and sizes from island to island?
Different finches settled on each island according to the environment that suited their abilities to eat, find shelter, and protect themselves best.
Each island had different food sources, so the beak shape and size determined which finch had a better chance to find food that would help them survive and pass the trait to the next generation.


Part B - Evidence
What evidence did Darwin have to support his claim?
The larger, thicker-beak finches lived on the ground and fed mostly on hard seeds.
The small, thinner pointed-beak finches lived on islands with no trees.
Long probing beaks were used to find food on islands that had abundant fruit.
Cactus finches had short parrot-like beaks to scrape the cacti.


Part C - Rationale
What is the rationale for Darwin's claim and evidence?
Natural selection occurs in a species as a result of an organism moving into an area that they are more likely to survive.
Adaptations occur in a species after the environment causes many new variations of traits to appear.
Natural selection occurs as a result of a species having a variety of traits. The variation that gives the organism the best chance of survival gets passed to the next generation more often.
Variations are traits that occur in all species and allow for an organism to survive and reproduce.

Answer 1

Based on the provided scenario and the options available, here is the completed claim:

**Part A - Claim:**
Each island had different food sources, so the beak shape and size determined which finch had a better chance to find food that would help them survive and pass the trait to the next generation.

**Part B - Evidence:**
The larger, thicker-beak finches lived on the ground and fed mostly on hard seeds.

**Part C - Rationale:**
Natural selection occurs as a result of a species having a variety of traits. The variation that gives the organism the best chance of survival gets passed to the next generation more often.
