Casually Explained: Evolution

  • Published on Jan 3, 2016
  • Although first published in the Origin of Species by Charles Darwin in 1859, the theory has gone through many small changes to become what it is today.

    Ok, real talk for a second. I owned Ducks when I was a kid and they’re super dumb. But the worst thing is it’s like they’re proud of it too. Like our ducks use to lay eggs and literally forget where they laid them and when you tried to say “hey chad, your nest is over there you dumb duck” they don’t give a shit and peck at your shoelaces because they’ve forgotten why they’re there and just want bread crumbs.

    What about the Meteor 12,000 years ago? Where people speculate that people who existed before 12,000 years ago had more advanced technology then we do today. Just in a different way.

    Spore isn't that bad, the beginning is quite fun actually, but the tribal stage is really annoying and the space stage is tedious. The civilization stage is alright and i got through it pretty quickly

    I refuse to believe that these discussions were made by fully grown educated adults. I mean seriously. "If we evolved from monkeys, why are there still monkeys?" I can't believe some people's inability to understand basic concepts.

      That tends to happen when otherwise rational people's brains are hijacked and corrupted by the self-righteous, dogmatic, Bronze Age drivel contained within the pages of the Goat Herder's Guide to the Universe (aka the Buy-Bull).

    I really feel sorry for scientists. They spend all this time trying to disprove God. I don't have any hatred towards them, as they are unknowingly submitting to what the devil wants them to do. God made us, nothing will change this fact. We did not evolve from monkeys who evolved from squirrels who evolved from fish lol (if you think evolution is how we came to be, then tell me why my grandparents parents were not more monkey like? Case closed!)
