how does evolution work?

Thanks in advance. I come from a Christian school so they don’t teach evolution because they don’t believe it.

I’ll give an analogy that simplifies it.

You are a mix of your mom and dad, but *mutations* in your genes can happen that are different from your mom and your dad’s genes.

So, let’s imagine a bunch of brown rabbits living in a brown forest, where their fur keeps them camouflaged from predators. Now, for whatever reason, this bunch of rabbits starts moving North, where it gets colder and colder, and thus more snow.

As the rabbits reproduce, *some* of the rabbits have a mutation that causes lighter-colored fur. As the rabbits move North into more snowy territory, more of the darker rabbits get picked off by predators, where the lighter-colored rabbits survive more.

As the lighter-colored rabbits reproduce more, and mutations create offspring with even *lighter* fur, and so on, eventually you have a population of rabbits where they’re all white.

This is evolution. There is no conscious process behind it, it’s just natural selection where the organisms with beneficial traits survive more, while those with less beneficial traits die off.

Take that analogy, and apply it to ALL traits any organism has, and that’s how evolution explains the diversity of life we have on Earth.
