INTERESTING FACT OF THE DAY

Do your nostrils join together at one point? I.e. are your airways like a Y shape? (if that makes sense)

Maybe it's true for Daniella Westbrook?

So how come I can do it too?

Maybe you're getting confused with the fact that each nostril can only smell certain smells. This may overlap, and both nostrils may smell the same smell, but there are distinct smells for each nostril.

FACT.

Also, the nostrils are arranged in a Y fashion, just up behind the skull, and the mouth joins the pipe just below that.

Well, if it is indeed in the shape of a Y, unless there are valves at the end of each nostril (i.e. where they join) there will be air movement up each nostril. due to lower pressure created by the other nostril sucking in air.

Huh? I can breathe through both nostrils at the same time.
Have none of you ever French smoked? The smoke goes up both nostrils.


Ok. Nostril fact. Emm. There are (way) more genes in the Human genome that code for smell recognition that there are for vision.
Odd when you think about how crap our smell is, and how good our vision is.

But, making more sense when you think that acute vision is new compared with smell. Dinos etc I suppose were the first guys to get really good vision.

lots of genomes, not many receptors / not many specific receptors?

?
ehh... single genome, many genes encoding for many smell receptors.
All of which are quite specific.

(It's also possible that there are fundamentally more "atomic" parts of smells than "atomic" parts of light. Meaning you need to have a bigger receptor set to catch them and build a meaningful picture. )
