BECAUSE EVOLUTION MEANS NEVER CHANGING:

Sluggish Reptile Breaks Speedy Evolution Record (Jennifer Viegas, 3/24/08, Discovery News)

One of the world's most laid-back animals, the tuatara, may be the fastest evolving creature on Earth, according to a paper in this month's Trends in Genetics.

The lizard-like reptile's DNA changes naturally at a rate faster than has been observed in any other animal: 1.56 changes per nucleotide (DNA subunit) every million years.

The finding is particularly surprising in light of the fact that the tuatara, endemic to New Zealand, hasn't changed much physically since its ancestors hung out with dinosaurs 225 million years ago.


This isn't parody either.

"[E]ndemic to New Zealand"? "[E]ndemic"? Is the author a super-duper-deep ecologist who thinks all life is a disease? Sheesh! (That's "indigenous," Ms. Viegas...)
