A lot of times, selective breeding is used to illustrate some of the process of evolution, but selective breeding actually punches a giant hole in the natural selection process of evolution theory.
Think about this: Natural selection depends on random mutations that favor some survival in certain environments, and this, supposedly after gobs of very random mutations and time, makes for new species.
But selective breeding by humans is done with very careful selection of mutations specifically to create certain traits or exaggerate others. It can cause change in a much shorter timeline. In fact we have some creatures used for genetic research like Drosophila melanogaster that have been bred for countless generations to drive change and show how natural selection "works".
But guess what? NOT ONE creature, even with countless generations of very specific selection, has been made into a NEW and distinct genus. No amount of selective breeding can make a cat into a dog. There are countless weird dogs, but every one is still a dog and inherently dog in nature. It doesn't start to become a bear or cat, or raccoon no matter how much it might kind of resemble something superficially. No amount of selective breeding will make a mouse into a rabbit. They even start out extremely similar. There are tons of examples where centuries of breeding weird variants and they all still fall into the same genera. Guppies are still guppies, goldfish with giant pop-eyes are still genetically goldfish, tomatoes are still tomatoes -- can't even squeak out an artificial eggplant. No amount of selective breeding can even make a fruit fly into a house fly.
These things aren't even big leaps, just the simplest tiniest changes and we can't even make bacteria, with millions of generations of selection, become a new genus of bacteria. It's still the same type of bacteria with some different traits. It's not now a multi-celled creature. Not once have we been able to even turn a single-celled rapidly reproducing genus into a multi-celled creature.
Given all of the very very focused efforts put into selective breeding and not one single micro-leap into a new genus and you want to believe that random mutations created all of this stuff, countless genera that exist from some single-celled bacteria. What can't even be duplicated in the smallest increment in a lab with focused effort is expected to happen randomly over and over and over to where there are all these unique genera.
It sounds like a joke to try and believe that.
