Tucker Carlson on evolution: what the evidence says · JRE #2138

“there's no chain in the fossil record of that at all. And that's why you don't actually hear people. You hear them make reference to evolution, because the theory of adaptation is clearly, obviously true. But Darwin's theory's totally unproven. That's why it's still a theory almost 200 years later.”

What the evidence says

Carlson claims the fossil record contains no transitional chain documenting common descent and that Darwinian evolution remains unproven, still "just a theory" nearly 200 years after Darwin. The fossil record contains numerous documented transitional forms; a prominent example is Tiktaalik roseae, described in Nature in 2006, a Late Devonian (~375-million-year-old) fish with intermediate fish-and-tetrapod features that illustrates the water-to-land transition. In science, a "theory" is a well-substantiated explanation of the natural world supported by extensive evidence, not an unproven guess, so a claim remaining "a theory" does not indicate weakness or lack of proof. The assertion that no transitional fossils exist is contradicted by the documented fossil record, and the "just a theory" framing misstates scientific terminology.
