Question 20 of 20

20. Question
2 point(s)
Why do collagen proteins found in dinosaur fossils present a conundrum for the evolutionary view of origins?
- given the evolutionary age of dinosaur fossils, all soft tissue such as collagen should have broken down a long time ago
- given the evolutionary origin of dinosaurs, they never should have had any collagen
- given the evolutionary origin of dinosaurs, the amino acids present in their collagen should be different than what has been discovered
- dinosaur fossil collagen does not present a conundrum for the evolutionary view of origins
