One of the biggest mistakes you can make in life is believing that you know everything there is to know. Even if you’re highly educated and brag about how brainy you are, there’s always—always!—something new to learn. If you keep your curiosity alive and well, and stay humble, you might fill in some of the biggest knowledge gaps you didn’t even know you had.

Tilapia skin is close enough to our skin that it can be used to paper over burns and let them heal faster.
Also, our immune systems are similar enough to pigs' that they are the (non-primate) animal that transmit diseases the most easily to us, which is likely why many early religions banned pigs as dirty.

Your memories are not concrete. Every time you think about a memory it becomes volatile and can be changed. There was an experiment where people were told that they had committed a major crime earlier in their life. This was of course false, but after being told repeatedly for weeks the people became completely convinced that the crime really happened.

* extremely efficient legs, we can walk all day, but a horse or a wolf tires out much earlier.
* resistance to shock, losing a body-part isn't a completely lethal, as with other creatures.
* hyperactive scar tissue, we regenerate faster than other creatures.
* Mega-fauna, we are in the group mega-fauna, which means we are one of the largest creatures on the Earth.

Dunno if this counts exactly but coconut water can be used as a temporary replacement for blood plasma. Yaknow, like, for emergency surgery on a stylised desert island?

That females are born with ~2 million eggs already in their ovaries, although that's down from a peak of 6 to 7 million while in the womb. They lose eggs over time naturally, and by the time they hit puberty they're down to ~300,000.
Still debate on whether or not they create new eggs in their life-time or if what they're born with are all they'll ever have, they're still doing studies to try to figure this one out.

Human babies are so helpless when they’re first born because they’re not done developing yet. It has been hypothesized that when humans evolved to walk on two legs, one of the consequences was the narrowing of the birth canal, meaning that babies need to be born earlier or else their heads would be too large to pass through. In theory, a human gestational period would ideally be between 18-21 months!

That muscles can exert a lot more force than they actually do. They aren't used to there full potential all the time because it would destroy the muscle.

The acid in your stomach could burn your skin! I always thought that was pretty interesting, and reminds me of the scene in Alien, where the alien blood burns everything.

It's funny but the nail on the middle finger grows faster than the rest. And the nail on the middle finger of the leading hand is generally a champion in terms of growth rate)
We still don't know why but the growth speed of the nail is somehow connected with the length of the finger, so that fingernails on long fingers grow faster than all, and the slowest on short ones.
