How Humans adapt to their Environment.

"You must not lose faith in humanity. Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty." - Mahatma Gandhi

So i'm finally back, and i'm going to carry on my so called 'mini-series' of adaptations - and we're onto the subject you should be most familiar with...

Yourself!

Humans adapt in the most simplest ways. Most of the time its too simple to even acknowledge it. If its cold what do you do? Well, you put a coat on! That is a human simply adapting to their environment, and if its warm what do you do? Well you take clothes off. Simple as that. These are the most basic of adaptations in humanity.

Another is the ability to drink milk. Seems weird, right? But seriously, being lactose intolerant was the actual gene for an ancient human. We could not drink milk/dairy. People would drink it, but would get sick from it. This carried on happening until someone had a mutation that made them able to drink milk etc. They would them go on to survive longer (due to more food, milk) than the humans with lactose intolerance, so eventually most people who cannot have milk will die out, and lactose tolerance will prevail!

We also do it in places like Chernobyl, or radioactive places. Even outer space. We wear radioactive suits, and space suits to protect us from what is out there. Radioactive suits protect us from getting radiation poisoning, which could lead to cancer, and then death. And the space suit protects us from the vacuum of space, protects us from choking and even suffering from 'The Bends.' Which is basically when bubbles form in your blood. (I will go over this in my next post)

Thanks for reading, Ben.
