Hello, my name is Bill the mole rat! I'm going to take you through the process of natural section in my species.
Early Mole Rats
Trouble in Paradise
Doesn't bother us
I'm outta here

Where is everyone?
Let's switch to first person narrative; Decades ago, me and my family lived in the ground (because we are natural burrowers), but we had some neighbors, the ants.
Back to The Future
The ants would sometimes bite us, and hurt us with chemicals that didn't harm us, but their bites stung! However, some of my family were less hurt by the stings. Many members of my family left our home because of the discomfort. We later found out that a part of RNA is certain individuals caused them to feel less pain.
How It Happened/Results
At first, many mole rats were gone from my home, while the ones who didn't seem to feel the pain stayed. The ones who stayed had a pain-tolerance gene, and were soon the only ones living in my home.
Now, generations later, my family has almost tripled in size and none of them are bothered by the bite of the ants.
This was caused by the more sensitive mole rats leaving our home, and the more tolerant ones staying. Because the were mole rats who didn't habe the gene left, the ones who did breeded with eachother until there were no sensitive mole rats in our home. This version of natural selection allows us to live peacefully with our neighbors, without pain.
