Two reasons. Either they offer some benefit, or they cause no harm.

My mom had dark brown eyes. My dad had light brown eyes and siblings with blue or green eyes. I have brown eyes, my wife has green eyes.

We have a kid with brown eyes and one with blue eyes.

So...I inherited brown from my mom, and my dad must have been a carrier for blue and passed that on to me. It was recessive, but did neither me nor my dad any harm. My wife must have blue and green, with blue being recessive. It caused her no harm.

One kid inherited brown from me, which was dominant over whatever my wife gave her. The other must have inherited recessive blue from both of us. It has caused him no harm. His child has blue eyes.

So recessive blue has passed from one of my dad's parents down to my son and grandson, even though my dad and l had brown eyes, because there was no reason for it to die out - it caused no harm.

Probably both. Water flows slowest right next to the bottom or sides of the river and faster out in the central. deeper parts, farther from contact with the ground. So in a flooded river, the middle part is even deeper and therefore faster than usual, but the parts that have spread out onto the shallow flood plain move much slower than usual

I think those examples, as you mentioned in the first example, the cognitive dissonance part, is the discomfort your brain feels in trying to either ignore, or somehow reconcile you conflicting beliefs or actions. If you're fully aware of the contradiction, and have decided to live with it, there's no dissonance, but if you're somehow still believing two conflicting things that are inconsistent, and haven't quite sorted it out, that's the "dissonance" part. The brain pain that creates.

There is no such place as "America", but it is often used as a short name for The United States of America. You should have offered North America and South America as options.

So how did we get that endurance and running gait? However it evolved, humans are capable of covering longer distances in a day than most mammals, and do it voluntarily. And sled dogs might only be capable of keeping up, or beating us, because we selected them for it

There actually is a real condition of damaged penis called Peyronie's disease, and one cause of it is overly aggressive squeezing. So this joke has a grain of truth

I really wish that we could get rid of this silliness. If I as an English speaker say "Deutschland" or "ParEE" (Paris) people look at me strangely, but those are the actual names as spoken by the locals. At least with Beijing, the Chinese Government corrected how it was translated into English, to give a pronunciation that is closer to the actual Chinese pronunciation, than the old "Peking".

When I was briefly taught upright bass, they told me to use the ring finger to assist the pinky. But maybe that is just for kids?
