“What creature first crawled out of the prehistoric swamps to conquer the land? The question has long puzzled paleontologists because the transitional species seems to have lived during a mysterious 30-million-year gap in the fossil record called Romer's Gap.”
Wait a cotton picking minute!! Are they saying sea-to-land evolution supposedly occurred during a gap in the fossil record? This isn’t just one person’s opinion either because they’ve even named the gap. That can’t be right! But read on:
“The late Devonian period has is a rich fossil history of lobed fishes.”OK, so we have a “rich fossil history of lobed fishes.” I guess that means a lot of fish fossils.
"After the Devonian the fossil record disappears, at least for a while—20-30 million years. Only three informative fossils dating back to this time have been found."I about fell out of my chair. Only three informative fossils? Are you kidding me? We’ve reconstructed the entire fish-to-land story based on just three fossils!! This must be a joke. But read on:
“When the fossil record resumes roughly 25 million years later, there was already a tremendous variety of tetrapod landforms. Ancestors of modern mammals, amphibians, reptiles, and birds had already evolved and were diverging along distinct branches.”I guess it’s not a joke. They have fish - next they have tetrapod landforms. In the interim we have three fossils - I guess now we have four with the new one discussed in the article. But of these four, only the most recent one is considered transistional.
Darwin was concerned about the lack of transitional forms in the fossil records – as well he should be. I guess the lack of sea-to-land transitional forms makes some modern scientists a little nervous too. Again, we have this candid quote from the article:“But, as by this theory innumerable transitional forms must have existed, why do we not find them embedded in countless numbers in the crust of the earth?”
“But just in proportion as this process of extermination has acted on an enormous scale, so must the number of intermediate varieties, which have formerly existed on the earth, be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and gravest objection which can be urged against my theory.”
‘"We lack a focus from which all modern tetrapods evolved," said Robert Carroll, professor of zoology, curator of vertebrate paleontology at Montreal's McGill University. "Romer's Gap is a 30-million-year black box that, frankly, keeps me up at night."I can almost hear a collective sigh of relief. They’ve invented an elaborate theory about sea-to-land forms and have been searching desperately to find even ONE example. Now they’ve finally found something they can pin the "transitional" label on. This critter is no more a sea-to-land transition than the man in the moon.
Clack's latest find may help scientists sleep better.’
