Question

What did Darwin think about Earth and life while he was forming his theory of evolution? Earth changes slowly over time, so populations might, too. Earth might cause fast, rapid changes in the traits of individuals. Earth cannot sustain large populations, so many animals become extinct. Earth does not change much, so populations must adapt to survive.

Answer 1

Earth changes slowly over time, so populations might, too. This is probably your answer.

Answer 2

Correct answer: "Earth changes slowly over time, so populations might, too."

From Charles Darwin' observations, he saw how the Earth also changed over time. He was once present at an earthquake where the ocean floor was lifted about 3 meters above sea level. He found fossil seashells in higher planes than that of the ocean's level. All of these and other findings led him to think that if the Earth had such slow but dramatic changes over time, living organisms could as well go through changing processes over time.
