Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Charles Darwin viewed the fossil record as
A
evidence that Earth was thousands of years old
B
a detailed record of evolution
C
interesting but unrelated to the evolution of modern species
D
evidence that traits are acquired through use or disuse
Explanation: 

Detailed explanation-1: -Answer and Explanation: Charles Darwin viewed fossil records as evidence that Earth was thousands of years old. This was because he recognized many of the fossilized organisms that formed part of the fossil record did not exist anymore.

Detailed explanation-2: -Darwin may have viewed our own fossil history as just another gap in the fossil record-one which might never be filled by hard evidence.

Detailed explanation-3: -During the first years of the voyage of the Beagle, Darwin collected a considerable number of fossils of mammals from different localities in Argentina and Uruguay. He found the first fossils at Punta Alta September 23, 1832, and the last in 1834 at Puerto San Julián.

Detailed explanation-4: -The fossil record supports Darwin’s theory of evolution that states that simple organisms can evolve to become more complex. The fossil record clearly shows organisms that evolved over millions of years to become increasingly complex.

Detailed explanation-5: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
