Uh, is this article hinting that horses were big, millions of years ago, but, through large amounts of CO2, eventually adapted and became the diminitive eohippus? And then got big again later? Adapting through dwarfism??

Also, I thought that the fossil record showed dragonflies with wingspans of 2 feet or more. The old theory was that different atmospheric makeup allowed such growth. Now, we're being told that poor atmosphere led to low-quality vegatation, and thus, slower insect growth.

I know science is supposed to change and improve as new information comes in, but much of evolution theory strikes me as CYA after new information destroys the old model. They don't throw out the theory, they just twist their brains around the new information so that it can fit the same old theory.

The dragonflies in question lived during the Carboniferous period, long before the age of the dinosaurs. Researchers studying fossils from this era believe the amount of oxygen in the atmosphere was a bit higher than today, allowing for larger insects.
