40 Haunting Real-Life Facts You’ve Probably Never Heard Before

HOW THE F**K DID YOU THINK THE BLACK PLAGUE SPREAD?

Fleas

And corpses

correct me if I'm wrong, but I thought it came from rats.

Fleas on rats. Rats were everywhere due to the lack of sanitation, thus their fleas were also all over the place, too.

Lack of sanitation, and superstition that cats were evil and had to be killed/ expelled.

Rats are still everywhere.

i think all 3.

bubonic plague, not black plague. that one came from flies and corpses

We all have Neanderthal genes. It's weird.

Those in Africa don't, last time I read about it

Which would make sense, since human life is supposed to started there and spread over the world

Not sure if it was by consent though

Almost. It is suspected that Sapiens gained the upper hand once we were able to communicate conceptually through speech and therefore form cohesive tribes that could be coordinated for attack and defense. But I’d encourage the interested reader to look up the latest anthropological consensus on that.

I need to disagree with that. All the genetic and paleontological evidence (like the gens for speech and hyod bone) show that other humans like neanderthals were capable of speech. Older humans like erectus did very complex behaviours, like boat building that require a lot of coordination and speech. I highly doubt that their desvendants were simpler.

I spend so much time thinking about this, it's just crazy to me

I think it’s just weird how our brains work like that! I spend lots of time thinking about things like that too. No shame in pondering on how our brains work! :)

Finally others. Everybody I've ever mentioned this to just looked at me like i was high. I may have been, but thats not the point

I had this same thought when I was about 12 and it has driven me crazy knowing that there really is no way to answer it

@Bex-Because Colors.

Cara G - That actually isn’t accurate. For starters, your eye isn’t what is seeing the image - your eye takes light in, but it’s your brain that interprets the signals your eyes send. (If your brain for some reason can’t interpret the image, it’s possible to have fully working eyes and still be blind.) And everyone’s brain interprets those images/colours differently. Also - not everyone has the same concentration of rods and cones which mixes things up even more - some see more vivid colours, some see less, some (called tetrochromats) can see colours that normal people can’t even see :) I have a friend who isn’t entirely red-green colourblind but those two colours are very muted for him, so him and I really do see red differently. Even male and female brains interpret colours/shades/hues differently - studies show that females are often better at identifying subtle different shades (“that’s not white, it’s eggshell! The one next to it is slightly more golden so it’s ivory” although that’s not a hard and fast rule). Different cultures interpret colours differently and some can identify more or less shades/hues than others, or classify them differently (for example, some cultures see light blue and dark blue as two different colours, the same way many western cultures see pink and red as two different colours even though pink is just light red). It is actually a highly subjective thing!
