Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

A lot of Bioluminiscence, but Infrared light as almost in any living be, which we can't see without special devices.

It's different from the blackbody radiation that body heat produces.

Structural weakness not only in the lower back, but also in the knees. The human being still has many reminists of an quadruped, as one of the younger species. He still has a way to be optimized as bipedo. Lower back and knees are still not optimized for this, apart of some other static and organic problems. We are still in phase beta.

Evolution doesn't follow the rules of intelligent design anyhow. If they did, we would all be crabs.

Infrarojo is different from light visible only by wavelength and energy.

Nothing to do with intelligent design, evolution is a self -regulating process due to environmental conditions. Given that the life of a human being is relatively long, naturally last generational evolutionary changes in a very complex organism, due to viable positive genetic variations, where a 99.99% is not, much longer until optimization. Somewhat more than 2 millon years isn't enough for this, less with continuous changes in the environment and conditions. Simple organism with a short life cycle can optimize in days, but complex organism like humans can't. Other beings have needed hundreds of millions of years for a perfect body, but with the price of already have the veto of evolving more. After perfection there can only be decay.
