Harsh islands

Let's add harsh islands where, each turn, weather conditions change, killing animals below a certain level of skills. Hypothetically, that should add space for the luckier and more skillful ones, which, in turn, will result in a natural selection phenomenon—as baby's survival skill is dependent on the parent's survival skill, the survival skill of the entire population, on average, will start to grow. That's the theory—let's check if that will work, and if it will, how fast this improvement will be.

The good news is, we don't need to add much code. We only need to introduce this new type of island by inheriting from the original code and add just a few lines of code. Take a look at the following snippet. Here, we're inheriting ...
