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.

1. Random mutation.

Every baby is a rough combination of mom and dad. That’s it. Sometimes something new shows up, like someone who is taller than normal (taller than both parents), or maybe the kid’s tooth enamel is like 1% harder. It’s totally random. Most of it doesn’t really help or hurt.

2. NONRANDOM selection.

Sometimes… the girls like a tall guy… or maybe his body can actually get rid of the microplastics… it doesn’t matter what it is. If it helps you have babies, raise babies, increase survival rates, etc, then you’re more likely to participate in .. breeding. Your kid is a rough combination of you and the other parent, and there’s a 50% chance that kid gets whatever you have.

And so over time… everything changes a little. The ones that breed better become more numerous. The ones that don’t… die. If you die without kids, you take your genetic information with you. If you have kids, your genetic information goes forward.
