Answer to Problem 4A
Correct answer :
The correct answer is option A. Earth and life are recent and have remained unchanged
Explanation of Solution
Explanation/justification for the correct answer:
Option A. Earth and life are recent and have remained unchanged −When Darwin took a voyage on the HMS Beaglein 1831 , people believed that earth was only 6000 years old. Almost everyone including young Darwin believed that plants and animals were unchanging.
Hence, this is the correct option.
Explanation for incorrect answer:
Option B. Species evolved rapidly during the first six thousand to a few hundred thousand years−When Darwin took a voyage on the HMS Beagle in 1831, people believed that earth was only 6000 years old. Almost everyone including young Darwin believed that plants and animals were unchanging. Hence, this is not the correct option.
Option C. Earth is billions of years old, but species have not evolved- When Darwin took a voyage on the HMS Beagle in 1831 , people believed that earth was only 6000 years old. Almost everyone including young Darwin believed that plants and animals were unchanging. Hence, this is not the correct option.
Option D. Species have evolved on earth for billions of years−When Darwin took a voyage on the HMS Beagle in 1831, people believed that earth was only 6000 years old. Almost everyone including young Darwin believed that plants and animals were unchanging. Hence this is not the correct option.
