Evolving Thoughts: What is a species?:

If somebody asked me to write a short essay giving an overview of my favourite topic, the nature of species, I doubt that I could. I can write a long essay on it (in fact, several) but it would be excruciatingly hard to write a short one. For that, we need a real writer. Carl Zimmer is the guy. He has an essay on species in the current edition of Scientific American. And despite quoting some obscure Australian philosopher, it is a good summary of the issues. How he manages to get up on a topic like that amazes me. It took me a good five years.

Muppet Show, season 3, disc 2, episode 1

Alice Cooper.

Needlesstosay, I'm quite content.

and it MORE than makes up for the sad tragedy of a show that was Leo Sayer 5 episodes earlier. :)
