Can someone here explain to me how narwhal tusks spin in the same direction? All other animal tusks point/spin in different directions from one another.
>>7772660
because evolution is not real, otherwise the narwhal would also have tusks spinning differently.
If i recall, it's the spiral nature of the tusk that keeps it relatively straight. That and nature would select against a curled tusk due to increased drag through the water.
>>7772695
That's not what op is talking about...
>>7772671
Why did God spin the tusks of all other animals differently than the narwhals' then?
Its not a tusk, its a tooth.
>>7772660
Not exactly an expert on this, but here's some possible reasons:
>little to no selection for different spins
>little evolutionary time to allow for mutation in the tusk-spinning gene
From those assumptions, I would conclude that whatever gene or genes that are responsible for the spiraling are very similar in every narwhal
>>7772709
Following up with some after thought.
The direction of the spiral may be related to the organization of cells in the area during development.
However the point still remains that there's little variation in this between narwhals
>>7772707
>This is what evolutionfags actually believe
>>7772728
All tusks are teeth, the only difference is that tusks protrude further than a tooth would.
>>7772660
There just hasn't been a mutation in the gene. Give it time, anon.
>>7772704
maybe he just spun the tusk of the narwhal differently from all other animals instead.
>>7772660
Maybe it has a trait that makes the tusks spin asymmetrically, similar to whatever trait allows the tusks to develop asymmetrically in size.
>>7772660
Perhaps the teeth that the tusks used to be were both on the same side of the face before they moved.
>>7772660
Its tusk reminds me of ice cream.
>>7772848
Though rare, there have been a few double-large-tusk narwhals, and they have the same spiraling so in any case the traits don't seem to be interdependent.
>>7772857
Maaaang, animals with asymmetrical parts amaze me.

Because they are the jedi of the sea
Nobody on /sci/ will know the answer to this because we're all a bunch of fucking idiots
Might have something to do with stereo-isomers
but I have no idea, its a random guess
>>7772733
This.
It isn't a HORN.
>>7773539
if it is a tooth, then why are they not used to chew ?
>>7773511
full on retard holy fuck, jesus christ I have cancer just from reading this
>>7773581
Come on, use common sense, they are obviously far too large to chew with. Next time you eat soup try to use a shovel and you will know what i mean
>>7772660
It's because the narwhal is asymmetrical. The "horn" (tooth) is always elongated on one side. The tusk spins outward because of the properties of the root cells. Now, why is the tusk always on one side? I have no clue.
>>7774411
>always
Nope
>>7772660
Assymetricality.
Most cetacean skulls are assymetrical, so it isn't very odd.
>>7774461
Aside from very rare random mutations, it is always the canine on the left side of the upper jaw. Some have a double tusk defect, but it's rare.
I don't see why this is a big shock to people. What side is your heart on? Which one of your lungs is bigger? Does your large intestine curve left or right? Are any of your organs located symmetrically in your body? Do any of you have perfect facial symmetry? How about your teeth, how many people had braces as a kid?
>>7774411
>>7774512
For that explanation to make sense, the two tusks shouldn't spin in the same direction in those mutations
>>7773608
Not all teeth are for chewing
See Elephant Tusks
>>7774573
It might, since it is a mutation. If the allele dictates a counterclockwise spin, theres nothing saying that a mutation should have a clockwise spin.
>>7772660
You ever watch Gurren Lagann?
Maybe it has to do with the fact that the narwhal has adapted to swim through water... less turbulence
