  • Same here. Evolution doesn’t work that way. It’s basically the opposite. Species don’t evolve to solve a problem, they evolve randomly and sometimes that solves a problem for them. Or sometimes, it pushes the species into a very narrow niche where its survival is ensured as long as the current extremely precarious situation they find themselves in doesn’t change.


















  • A space heater in space could only transfer its heat through radiation instead of conduction and convection, so only a small portion of its heat would escape. It would get hotter and hotter until it melts and stops working.

    Essentially, that’s how the ISS regulates temperatures. It has big external panels that radiate excess heat into space because there’s very little matter up there to conduct heat away.
