Transitional fossils are consistent with Darwins theory of descent with modification. Which of the following, if possible, would dissprove it?

A. Bird fossils appearing deeper in the fossil record than all dinosaurs

B. Tiktaalik rosaea fossils appearing deeper in the fossil record than all fish

C. Fish and amphibian fossils occuring together at the same depth in the fossil record

D. Only A and B

E. A, B, and C

Solution

Tiktaalik rosaea fossils shows the tetrapods (adapted for land) have been evolved from fishes (adapted for water). Tiktaalik rosaea fossils which is a transitional form shows tetrapod like forelimbs and mobile necks unlike other fishes. A four winged dinosaur, Microraptor gui has been the transitional form between dinosaurs and the birds. Birds and the four winged dinosaur, Microraptor gui have been similar due to the presence of feathers. Thus the evolution of birds and tetrapods are consistent with Darwin’s theory of descent with modification. The transitional fossils have been forming a link between their ancestors with modern day species. Thus the limbs of tetrapods came from fins or evolution of feathers from scales has not taken place on one day but the evolution was slow with transitional forms. Fish and amphibian fossils occurring together at the same depth in the fossil record is against the Darwins’ theory of descent with modification.
