Today I read that a scientific paper has hidden a face in a turd. Who could it be?

The paper is research in faecal genomics, sequencing DNA in turds.

 

 

It’s aims are fair enough. It’s easier to collect DNA from faeces than from wild animals. A catch is that faeces tend to have DNA from a lot other things in their guts, like gut bacteria. If you’re wanting to DNA sequence the animals that pooped, that’s a hassle. It there a way to do better?

 

 

On the third page in the top-left of Figure 1 there is a baboon.

 

 

The baboon looks as if it’s just pooped. (And is looking at its turd?)

 

 

Looking closer, that turd might have a face in it.

 

 

Or this just pareidolia? Let’s look closer.

 

Who could it be?

Update

It turns out that putting faces in turds makes your paper popular. This paper is now easily the most popular paper in that journal, nearly four times as popular as any other –

There will editors, and readers not in on the joke, wondering just why a faecal genomics paper is that popular…

Disposal

Update: the offending object has been flushed.

You can stop downloading the paper trying to find the face. According to CDC and elsewhere, the journal has removed the illustration has been removed. Apparently they have offered no comment.

Footnotes

It’s the weekend. I can write something more… relaxed. Yes, this is for real. I’ve taken all my screen grabs from the paper itself. Anyone who wants to save this for posterity ought to download the paper soon. It’ll probably get edited… (Now that’s one way to get your paper downloads up! Edit: It is too; see the Update, above the Footnotes.)

Here’s one reply to how reviewers could have possibly found this during peer review –

For the uninitiated, the third (hint, hint) reviewer is legendarily the one that craps on your paper. (Yes, I’ll see myself out…)

Hat-tip to Mick Watson for alerting me to the tweet by Jonathon Eisen.
