1. How might these locations later be used to support Darwin’s idea of slow, gradual change? Darwin started the voyage of the Beagle as a creationist, very much enamored with William Paley’s arguments in Natural Theology. Why did he ultimately reject the argument from design? What kinds of evidence did he observe on his voyage to support his idea that species changed through time rather than being specially created?
2. What did these bones Darwin found at Punta Alta imply? Why were there no animals like this alive and if the animals went extinct, how long ago did this happen? Darwin speculated that the vegetation must have been very lush to support creatures of this size. However, the vegetation in this region now was very sparse. What did Darwin conclude?
3. Speculate what caused the creature’s extinction. Must it have been environment change? How long ago did this creature die? If these bones were thousands of years old, did they support Lyell’s theory? How could Darwin tell or speculate, given his knowledge at the time
