why do we have butt cheeks i dont understand why did we evolve this way
what use do butt cheeks have
oh my god I HAVE THIS KNOWLEDGE
fun fact: butt-cheeks are one of the things that make us superior to other animals okay note that other apes do not have butt-cheeks
okay don’t quote me on this because I only did sixthform-bio and I’m sure of forgotten loads of stuff but here’s the down-low
back when we were evolving from ape to human, one of the most important things that happened was when our spine started meeting our brains at a sort of 90 degree angle instead of like 45 degrees, which meant that we could straighten up and walk on two legs which was a pretty rad development
except alas oh no our muscles weren’t built to allow us to walk around on two legs because that requires a sort of twisty motion of your hips as opposed to whatever the fuck it is everything else does AND SO ape-people started evolving with longer, narrower waists so that our bodies could twist with every footstep and we could strut along the fashionable catwalk that is neanderthal evolution
but then once this had happened, people realised that we had an advantage over other animals and we would be better at chasing and killing them but we weren’t very good at running
so that’s when we developed the glutenus maximus which is a really badass-sounding name for the muscle in your derriere which helps us to support our spine in an upright position so we don’t get tired, and helps the legs to rotate nicely so that we can run, and has a nice big fat storage around it to help us get energy so that we can run
and that, basically, is the butt-cheek
tl;dr - butt-cheeks were the result of thousands of years of natural selection so that we could run fast and slaughter things
reblobbing this for “fashionable catwalk that is neanderthal evolution”
also here’s a source that basically says the same thing.
Science!
what the fuck is this science bullshit

We Live In The Future
A team of physicists at the University of Dundee have created a real-life sonic screwdriver - yes, I’m serious.
The Doctor’s trusty tool was replicated using ultrasound energy capable of manipulating an object away from itself and, using a component of momentum which exerts torque on the object, a helix-shaped vortex beam then causes the item to rotate.
Researchers hope to use this breakthrough in ultrasound technology for future endeavors regarding non-invasive surgery, but we’re just hoping they figured out how to make it work on wood.

mchlhffm asked: How do you think Peter Parker would deal with the Young Avengers while trying to teach them Science in class? He was a high school teacher for a time, so why not teach young superheroes?
There is only one reasonable way of teaching them. In song. I’m sorry hun, I didn’t finish the song completely. I just do not want to look at this anymore /SOBS.
