1. the main process behind evolution, as stated by
Charles Darwin. Also known as survival of the fittest, meaning those with superior traits are more likely to pass on their genes to the next generation.
This is how life on Earth has progressed for millions of years, driven by instincts encoded into the DNA of all living things. But sadly, as a result of several factors, including exponential intelligence, irrational emotions, etc, the species Homo sapiens is slowing down in terms of evolution. Due to the successful creation of societies and advancements in the sciences of medicine, humans have become exempt from the laws of natural selection, leading to
degeneration within the species.
NOTE: THIS IS NOT A RACIST OPINION IN ANY WAY, SHAPE, OR FORM. THIS IS NOT TO BE CONFUSED WITH CRAP LIKE
SOCIAL DARWINISM OR BULLSHIT LIKE THAT. The point is, civilization has brought physical evolution of humanity to a halt. Medical and genealogical studies have revealed that those living in less industrialized or progressed regions or eras, differences in hygiene and anatomical knowledge aside, were more healthy and adaptable than people living in high-level civilizations. Or something like that.
Anyways,
that's my opinion. Natural Selection doesn't apply to humans as long as humans stay indoors. Due to lapses in judgment, the "Unnatural Selection" that we have imposed on ourselves will bring doom to our species. Have a nice day!
