A chacma baboon.
Human noses are often quite weak compared with the rest of the animal kingdom, making it hard for us to find out if baboons can be told apart by smell. Researchers therefore decided to draft much better noses — those of mice. The researchers swabbed the armpits and groins of wild chacma baboons (Papio ursinus) from two different troops of the primates in Namibia. They next tested 24 adult male Swiss mice to scents from 14 adult female baboons. They chose female baboons partly because "some male mice were peeing on male baboon odors as if they were in competition," said researcher Aurélie Célérier, a behavioral biologist at the CNRS and the University of Montpellier II, France.
Their research shows that mice can detect odor differences between individuals of the same sex and age class in another mammal species, and that the mice can perceive a higher similarity between baboons that are related than baboons that are unrelated. These results show that olfactory cues may play a role assessing the degree of relatedness in among individual baboons. Detective mice assess relatedness in baboons using olfactory cues by Célérier et al. (2010) was published on The Journal of Experimental Biology.

Whoever came up with the phrase" just dumb animals" were obviously talking about humans … we can learn a lot about close to family from these guys
Bah... I tried to access it through my university, and even though is says I should have access, it wouldn't let me... perhaps I need to try on campus...
Already got a copy, but thanks Michelle!
Fascinating!
I never really considered that mammals could have a greater 'smell' per males and females; I mean, it makes sense, but I casually assumed that it would be isolated in each species. The male mouse vs. male baboon pee-fest, though, is awesome (and interesting...).
I've also just discovered this blog, and am impressed! Would you be willing to forward that copy of the study (understandable if not). Thanks!
Sure amcouch.
Where should I send it to? And thanks for reading The Prancing Papio!
Hey Raymond... looks like I forgot to put down my email! It's amcouch AT gmail DOT com. Thanks!
