If something similar to our Moon hit the Earth, would it destroy all organic chemicals including microplastics?

Non-humanoid aliens

No.13553121 ViewReplyOriginalReport
We can only envision intelligent aliens with an advanced civilization taking on a humanoid form, because that's all we know.

However, our form is a consecuence of having evolved from apes, a series of long coincidences which first saw us evolve brachiation and opposable thumbs to climb and swing from trees (monke stage), then saw us climb back down and lose our tails as we adapted again to the ground (ape stage), and finally adopt bipedalism as we moved into the Savannah (hominini stage).

It's very unlikely this set of coincidences will repeat in the evolution of an alien species.

What other shapes could intelligent life take? They would need access to fire to develop metallurgy, and some kind of appendage to manipulate its environment.

are anti-aging drugs being developed? I don't want to die, if I ride it out until like 2050 will I be able to extend my life in perpetuity?

Genes and evo psych

No.13561844 ViewReplyOriginalReport
Evolutionary psychology makes a lot of claims about cognitive recognition, yet relies on genetics to be true.
For example it makes those claims:
>people evolved to find big eyes, soft skin and fluffy cheeks cute and so that helped babies survive, which is why babies look the way they do and why we're into cuteness
>tall men are preferred over small men because it makes the women feel protected
>women evolved to get sexually aroused by scenes of rape in the same way they'd get aroused by physical rape because it would have lessened damage to their genitalia
How would protein-coding genes make any of these true? Like what king of protein would make someone's brain able to detect cuteness from things not cute?

How would genes make a woman's brain recognize rape in a movie and subsequently make her turned on?
Hould would genes make a woman recognize height differences and enforce a height preference?

Was debating whether I should post it on /fit/ but I think this board will give a better, non bro-science answer.
Is working out in a sweatshirt&sweatpants in any way better than working out in, let's say, just shorts?
Is there any benefit to sweating more when doing exercise, whether it be cardio or weight training?
