Question

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


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.


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.

Answer 1

The incorrect statement is the second 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 not a correct example of fossil evidence for evolution:
- Evolutionary support comes from change over time (variation, transitional forms, loss or gain of features). Fossils that are identical to modern forms do not demonstrate change, so they do not provide evidence for evolutionary transitions.
- Also, tooth color is rarely preserved in fossils, so comparing "color" is not a meaningful point.
- The other statements describe transitional/intermediate forms, morphological variation through time, or lost structures (vestigial features), which are the kinds of fossil evidence that support evolution.
