4. Our ability to handle Ultraviolet Radiation

Ultraviolet Radiation is unlike all the other types of radiation we deal with on a regular basis. We actually do run into radiation on a regular basis via things like CT Scans, MRIs, and even X-Rays. All are low forms of it but still exist. Meanwhile, the biggest radiation we deal with is, well, the sun. UV Radiation comes right from that big ball of fire that heats the Earth.

The way we handle UV radiation with Melanin. For those unaware, Melanin handles things like the darkness of our skin, hair, and even the iris of our eyes. Melanin is a natural fighter of the sun, allowing things to get darker and lighter to fight off the sun’s rays. In fact, Melanin is the reason people tan when they go outside during the summer. Melanin naturally absorbs the sun’s impact, protecting the cells from damage. It does not do everything, so sunscreen is a must!

3. The reason you’re Black, White, Yellow, or Brown

Speaking of Melanin, the way your skin looks began thousands of years ago and it’s one of the most amazing ways evolution is proven in our bodies to this day! Remember, Melanin is a natural protector and darkens the skin when we’re tanning as a way to protect you from the sun. All of this is due to absorbing it. While it makes sense to us that darker things are hotter when absorbing the sun, the skin needs to be darker to fight it.

The hotter a place is, the more likely the natives to that area will be darker. This is why the Middle East has several brown people yet when you go to the United Kingdom, white people can be seen all over. Centuries ago, at some point, humanity split up with some going lower into the Middle East, Africa, and the rest of Asia. Meanwhile, others went toward the northern sector to places like Norway, Russia, and England. All are notably whiter nations for obvious reasons. We evolved to fit our territory.

2. The Human ability to consume Milk

When we’re babies, we consume milk quite often. This is either from formula or our mother’s breast(s), of course. Yet as we age, we eventually stop drinking milk and therefore stop producing lactase. This is the enzyme needed to break down lactose products well. That includes things like Milk, Cheese, Butter, Yogurt, and much more. Around 10,000 years ago, however, we began to domesticate animals like cattle.

We then began drinking the milk they produced, even using it for other products. Eventually, a mutation to the Lactase Gene allowed people to break down the contents but nearly 80% of the world is still Lactose Intolerant today. Yet we’re still able to eat or drink these products because of the random mutation. People may still get gassy or have an upset stomach from them, especially with overconsumption, but we no longer die from consuming it all due to this major evolutionary change.

1. Growing from a Child into an Adult

Centuries ago, we aged a bit differently due to living smaller periods of time. This speed at which life started and ended was rapid. This is why women grow up faster and stop growing by their mid-teenage years. They were needed to bring new life to a family. A girl at age 12 can actually have children, however, the youngest girl to give birth on record was only 5 years old. Boys grow slower but this is due to their specific needs for growth.

Both experience hormone changes but women experience a lot more at a faster rate, so give that teen girl crying for no reason a break next time. Boys grow slower and stop growing by their early 20s physically. The reason for this was due to the need for young men to always adapt their development to the environment they are in. On top of this, today we grow up slightly slower than we did back then. We even show our age later, which is why some can look much younger than they truly are.
