What are the evolutionary factors that explain the great diversity of nose morphology amongst humanity?
Have their been any in depth studies of the topic? What is the conventional wisdom theory? What does Dawkins have to say on the topic?

While you're at it -- What are the evolutionary factors that explain why cute little upturned noses on women are so appealing?

More diversity implies the lack of a particular evolutionary pressure. If certain types of noses were advantageous, we'd see mostly those kind and less of other kinds.

Nice man hands too. It looks like a homunculus model of the nervous system. Look it up.

Nuh uh. Nose shapes being localized indicates present but differing selection pressures.

because the air is free

>>16816533 (OP)
air intake is important the shortest unobstructed path is ideal, but some climates are dusty, or humid, or frozen

>>16816533 (OP)
all it is is lack of forward growth

>>16816533 (OP)
Okay you fucking high school drop out let me make it clear for your retarded ape brain:

Colder climates mean that air needs to be warmed before it's brought fully inside, so the nose is narrower where the surface area of the nasal cavity can sufficiently warm the air by the time it does enter the body. Warmer climates do not have such issues and the noses are designed to siphon in more air because temperature is not a consideration.

A theory I heard is big nose makes it easier to breath in the desert

>easier to breath in the desert
haha... fuck ... common sense dictates the OPPOSITE should be true. Constant dirt, dust, sand fucking flying all around ... herp derp... yeah, let's make sure these noses are as LARGE as possible to get all this shit into the lungs more effectively

>>16817991
It's an explanation based on your pseudorational world view and not supported by any data.

How about this counterargument:
- In hot climates air is dry and needs to be moisturised, for that purpose you need narrow nose with big surface area.
- In Italy, South France, Spain weather is never cold however noses are relatively narrow there.

big nose=generally adaptable people, great memory
Small, piggy nose=associated with poor memory skills

Better ability to smell indicates developed hippocampus.

>What are the evolutionary factors that explain the great diversity of nose morphology amongst humanity
That's like asking what are the "erosional factors" that led to the sphinx eroding its nose away. It's a brainlet and redundant question that doesn't even make sense. The "evolutionary factors" would be selection, mutation, and heredity. That's the answer.

You're using "evolutionary" as a filler word and that implies you're a /pol/ tourist trying to explain jew noses.

>>16816803
>Nuh uh. Nose shapes being localized indicates present but differing selection pressures.
You don't understand evolution . A mutation in an isolated population can genetically drift to the entire population without the need for any selection pressure.

you're the one here that is so obsessed with /pol/ that you imagine it hiding behind every post

>humid and warm climate - wide and broad noses (platyrhine)
>cold and dry climate - narrow and long nose (leptorhine)
basically, if the air you are breathing is colder your nose has to warm it first before reaching your lungs, and longer and narrower noses make it more efficient to do it.
it's the same with wide noses but they help to cool you off.

Did you mean short and wide?
Japan has phenomenal humidity and the Japanese consider tiny noses as a sign of beauty.
