Closing up shop

UPDATED to add incredible breaking news from Prof. Neil Shubin at the University of Chicago!

The LTEE has been running for more than 31 years and over 71,000 generations. It’s time to close up shop, as of today.

It’s been a hell of a lot of work, and we have almost nothing to show for it. As some brilliant commentators have noted around the web, the creatures in the flasks are still just bacteria—creatures, just as they were created.

If you read the first LTEE paper*, you’ll see we predicted the bacteria should become yeast by about 5,000 generations, nematodes at 15,000 generations or so, and fruit flies by 30,000 generations, maybe 35,000 at the outside.

After that, we’d have to stop the experiment anyhow, because we wouldn’t be able to freeze and bring them back alive any longer.

Plus, we’d have to get IRB approval for human experimentation if we ran it much past 50,000 generations.

Well, we’ve given the LTEE all this time, and still … they’re just bacteria. Same old same old.  I guess we’ve proven that Charles Darwin was wrong after all.

As an astute reviewer pointed out when we submitted that first paper, “I feel like a professor giving a poor grade to a good student …” I should’ve listened and quit way back then. It would’ve saved everyone a lot of time and effort.

Now it’s going to be a hell of a lot of work next week emptying the freezers and autoclaving all those samples.

Anyone need some old flasks?

UPDATE: It seems that I’m not the only scientist who was fooled by that Charles Darwin fellow.  Even Prof. Neil Shubin seems to have fallen hook, line, and sinker for the theory of evolution.

  1. I’ll have to quote Douglas Adams on this: “So Long, and Thanks for All the Fish” 🙂 Truly a remarkable long-term experiment.

  2. 😀 Nice joke for April fools’. Almost fell for it! 😉 Long live LTEE!

    Got me for four seconds, then I thought hang about . . . But you’re right: Once they become humans they’ll start demanding stuff and then . .

    Happy April Fools’ Day to you too, Dr. Lenski! Long live the LTEE, One of the Attractions of the Greatest Show on Earth – Evolution!
