This question asks about the scientist who studied geology that basically influenced darwin's observations during his voyage on hms vehicle.
00:09
So basically, darwin obviously studied biodiversity in south america and the gulf of those islands.
00:15
And he also saw geologic processes such as erosion and basically supported the idea that earth has always been undergoing slow gradual changes.
00:25
So when we see processes like erosion by wind or water, these processes have been taking place throughout earth's history in a gradual slow, like process.
00:38
So as we go down the list of scientists who basically had different ideas, we could see that first, erasmus darwin, so that was darwin's grandfather and he was a naturalist.
00:52
And he basically studied vestigial structures and those concepts, but it really didn't have anything to do with geology, so we could eliminate a.
01:03
B, cuvier, he actually proposed a concept regarding earth's history, known as catastrophism, so basically that there are these periods in earth's history that completely wipe out the biodiversity and have significant impact on the fossil record when we see that certain species just disappear, which obviously occurs, but darwin was more focused on the slow, gradual changes that were occurring on earth.

So we could eliminate b...
