The theory of biological evolution through natural selection was first developed by naturalists Charles Darwin and Alfred Russel Wallace in the mid-1800s to explain the number, variety, and variability of organisms that they observed around the world.
Since their time, many new discoveries have been made supporting the theory, including new knowledge of genetics and the chemical process of heritability.
But since the biological theory of evolution depends on scientific observations, which scientific finding, if it was ever made, would force scientists to radically change the theory?
A.
if a very famous scientist decided she did not like the theory
B.
if a very ancient species of animal was found to still be alive today
C.
if an animal's circulatory system was shown to be very complex
D.
if modern animal fossils were ever found in a very ancient geologic period
1 answer
The correct answer is D. If modern animal fossils were ever found in a very ancient geologic period, it would force scientists to drastically reevaluate the theory of biological evolution through natural selection. This finding would challenge the current understanding of the timeline of evolution and the origins of different species.
