1. While in the Galápagos Islands, Darwin observed two tortoises: the domed tortoise found on Isabela
Island (shown at top) and the saddleback tortoise
found on Hood Island (shown at bottom). Using the
draw pad tool, outline in red the part of the shell
near the legs and neck of each tortoise to show
how they are different.
Which island is more likely to have a habitat with
low-lying food such as grass and moss? Provide
evidence from your drawing to support your
answer.
