Evolution results in a clear directional pattern. C. Evolution is the result of interactions between organisms and their environment. D. Evidence of continental drift exists.
How does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart. D) The land animal fossil wasnt found in Asia which wegner thought was only stable continent that hadn’t moved.

(c) the sequences of DNA in their genes should be less similar (more different) than those of two more closely related organisms. (d) they should share more homologous traits than two more closely related organisms share.
