Paleontologists have discovered fossils of centipedes that are 414 million years old. These fossils are at least 20 million years older than the earliest land-dwelling animals previously identified. The paleontologists are confident that these centipedes lived on land, even though the fossilized centipedes were discovered in rock that also contained fossilized remains of animals known to be water-dwelling. The paleontologists' view would be LEAST supported by the truth of which one of the following? ['Fossils of spiders with respiratory systems adapted only to breathing air were found in the same rock as the centipede fossils.', 'The legs of the fossilized centipedes were particularly suited to being a means of locomotion on land.', 'Fossils of the earliest land-dwelling animals that had previously been identified were found in rock that did not contain fossilized remains of water-dwelling animals.', 'All of the centipedes that had previously been discovered were land dwellers.']
