Dinosaurs

Vax was the premier scientist on Earth. He was also a dinosaur, of the bipedal humanoid variety. He had been working on the problem of a rapidly heating Earth, where the temperatures were gradually increasing every couple of years or so with no end in sight.

Finally, after years of research, he came to a couple of conclusions. The first was that the temperatures would soon plateau to be followed by a rapid slide into subzero temperatures. The second was that his cold blooded species would be wiped out by the reversal of temperature.

He summoned his lab assistant Wurg.

"We have a problem," he began, as he told him about his discoveries.

"That's horrible!" Wurg said when he had finished. "What can we do?"

"I hypothesize that we may be able to survive, but only if we are able to engineer a pathogen to help us resist the cold."

"Can we do that?"

"I have been working on it..we will need to finish the research I have begun."

With that, they set to work at once. It wasn't easy and took a long time to complete. But finally, it was done, and the two set about injecting themselves as test subjects. But something was wrong. The serum they concocted were meant to awaken their primordial natural resistances. When they were activated, they began to feel themselves regressing. Their intelligence began to seep out almost immediately as they felt a rush of power in their bodies and a thickening in their limbs. They fell to the ground and began to walk on all fours.

The virus spread to the other dinosaurs and they quickly regressed to an earlier state of evolution, robbing them of their intelligence. Unfortunately, they were too late to save themselves. The ice age still struck and the dinosaurs were all but wiped out.
