The Tailbone of Humans Provided Evidence Against _____

Question

The tailbone of humans provided evidence against _____.  
A) evolution by natural selection
B) evolution by adaptation
C) the idea that each species was formed in its perfect state
D) the idea of uniformitarianism
E) the idea of extinction

Accepted Answer

The tailbone of humans, also known as the coccyx, is a vestigial organ that has no function and is a remnant of our evolutionary past. This provides evidence against the idea that each species was formed in its perfect state, as the presence of vestigial organs suggests that organisms have evolved over time and their structures have changed.
