Question

All of the following statements are correct about how fossil evidence of the shark supports the theory of evolution, except:

Many fossils of shark teeth have been found that show different sizes and serrations (saw-like edges). These teeth have distinct differences and similarities to modern sharks.

Many fossils of shark scales have been found that have features of enlarged scales that resemble a brush that modern sharks do not have or need to survive.

A new shark fossil has been found that has characteristics in the size of the teeth and serrations (saw-like edges) that are in between the older fossils found and the modern shark.

Many fossils of shark teeth have recently been found that are all the same size, shape, and color compared to the teeth of modern sharks.

Answer 1

The incorrect statement is the last one:

"Many fossils of shark teeth have recently been found that are all the same size, shape, and color compared to the teeth of modern sharks."

Why it's wrong:
- Fossil evidence for sharks actually shows lots of variation in tooth size and serration over time, not uniformity. That variation (and transitional forms) is what supports evolution.
- "Color" of teeth is not a reliable biological trait in fossils because fossilization and mineralization change color.
- Even if some fossil teeth resemble modern ones, finding many identical fossils would not be strong evidence for evolution and would contradict the abundant morphological changes seen in the shark fossil record.
