Most mutations are benign and neutral to selection. In general, selective forces only act on a very small number of traits with a small amount of pressure over a long period of time, otherwise you'd just have tons of extinctions.

Why is it common in humans? Probably just genetic drift in our early ancestors.

no reason really you can't have humans with a black sclera survive just as well, given they are smart enough

He's completely right.

>>8791513
No. For one he ascribes some strange significance to a completely arbitrary length scale.

>>8792031
He's not transfixed on some particular value. Any given value past the materialistically documentable works.

this is trivial and left to the reader as an exercise

Laying down the obvious every number is even, and every number is either bigger or smaller than the two next to it on the circle.
Plus four numbers are in the form 5000 + 2^n, where n equals 2, 4, 6 and 8

Very nice puzzle though, where'd you find it?

yeah man what's up with that

I think it's got something to do with angular friction

>Are they really as harmful as the media and general public portray them to be?
No.

>Are GMO's really that bad

No. Genera (http://genera.biofortified.org/wp/) has a fuck load of studies looking at their safety. But just to get you started:

>This study shows that a diet including insect-resistant Bt176 maize, fed to 53 ewes and their progeny for 3 years, did not have adverse effects on their health or performance and that no horizontal gene transfer to ruminal microorganisms or animal tissues was detected.

(source: http://genera.biofortified.org/view/Trabalza2008)
This one found some adverse effects, but it could be due to any number of things:
> There were no differences between pigs fed the GM and non-GM diets for feed intake, weight gain, mortality, and routine blood biochemistry measurements. The GM diet was associated with gastric and uterine differences in pigs. GM-fed pigs had uteri that were 25% heavier than non-GM fed pigs (p=0.025).
(source: http://genera.biofortified.org/view/Carman2013)

>The results of growth, mating, gestation, milking periods, reproduction and life span were not different between the GM Bt11 and non-Bt fed groups. The percentage of embryonic death, litter size, newborn sex ratio and body weight (21-60 days after birth) were not different between these groups. The life span of the third-generation mice did not differ over 1,072 days of observation. In addition, there was a tendency for a weight decrease among each group as the generations progressed, but there was no significant difference in performance among each group in each generation of mice.

I think there are close to 500 studies on there, so go nuts.

There is literally nothing wrong with GMO food.

Thank you, I'll look into that.

How stupid are you?

You might not die instantly upon landing, bad idea.

Might as well drink alcohol

I have a whiteboard at home, since I can't put up with chalk dust. However we have blackboards at university, blackboards are cheaper and I prefer the contrast; but ultimately there's no difference between them. Yes it's useful.

There's no reason to use chalk boards aside from stinginess

that force travels through the luminiferous aether, so it's literally the light.

>>8790199
The carrier particle for the electromagnetic interaction is the photon, but because the particle is virtual and so has undefined momentum it can do, yes.

How much do you know already? Are ypu comfortable with the basic plug n chug shit (gaussian elimination, determinants system of equations)?

I know almost nothing, just some basic matrix operations

Reused booster?

Biochem reporting in.
1/2 pack per day.

Because they're relatively not retarded

most of the grad students i know in math take frequent smoke breaks

There's very little selective pressure eon humans today, so no

hmm with OP in mind i wonder what sort of muntants will rise out of india and china within the next thousand years


Poop mutant that can control poo
rice mutant that can control rice

bummer i wont be around for it

>>8789025
>>8789030
Yes. More generations = more evolution. It doesn't matter which way the mutations go, it still occurs. Selective pressure for modern man is social now. Literally the opening of the movie Idiocracy:

More like the mutant will be better at gaining welfare and fucking sluts.

So you agree that climate change research is unscientific and relies solely upon observation, without any reproducible conclusions?

May I also ask how many crystals you own, and if you store them next to your chakra-aligner?

>>8788984
Well they have a hypothesis and are able to show that using that hypothesis, along with other well established tools, you can reach a conclusion that affirms the hypothesis. Moreover since they have a well defined hypothesis you can formulate conditions where that hypothesis fails.

I don't really see what the issue is.

It relates the square of the length of a right angled triangles' hypotenuse to the sum of the squares of the other two sides.

>he wants a week worth of lectures in a 4chan post

The theorem itself is self-explanatory if you've had algebra 1. The implications are that you can derive the side length or angle of any triangle, given any combination of 3 sides or angles (except 3 angles) by clever manipulation of the formula, and you can use it in related rates problems (like finding the ground speed of a plane or the linear distance between two moving objects) using the derivative (the function that gives you the rate of change at a specific point in time)
