I was with most of this until the selective breeding part. Did prehistoric humans have a concept of this? Do we have evidence of that? If so, that sounds rather interesting. I’m just a bit skeptical is all.

(Modern primates also throw stones, it’s not the evolution-killer on its own that the meme is making it out to be.)
No, the REAL thing that soared us beyond all members of the animal kingdom is how we started abstracting information and sharing it. IE: language, writing, and the cognitive processes behind those skills that allow us to plan ahead. Not just planning ahead, but being able to set up actions far in advance, like planting seeds because we know a plant will come out of it. Migrating to where animal herds migrate to so we can stay close to the food, and just the day-to-day actions like preparing a fire in advance so you can see when it gets dark, bringing things with you to use later, having an idea how to ration food, being able to share your plans with others, communicating your movements to other hunters, and yes, all this made us exceptional hunters. When other primates were still mostly foraging for plants and bugs, our ancestors used this “thinking” thing to start getting massive doses of meat. Amino acids, proteins, high-density fuel, food for growing brains.
Our story of how we got here is without question the most fantastic story ever. You are the product of over 4 billion years of uninterrupted successes. A family tree going back a thousands of millions of years without break, surviving apocalypses that have turned our entire globe to ice, to fire, to water and other unimaginable catastrophes.
So now you made it, your billions of generations of ancestors secured your survival against all odds, whatcha gonna do with it?

The impact of human fertility cycles ("concealed ovulation’) and human evolution is a vast, deep field of study and speculation in itself, but I am making some very sweeping generalizations here, referencing people’s capability to choose when to reproduce on the broadest levels, not that there was a period or specific instance of this having an impact… more like, it made a difference over very large scales of time, as evident by the fact that our breeding cycles are nothing like most other mammals.

I mean, every existent species is the result of millions of generations. We all fill our niches, until we don’t. So even the humble tortoise is just as remarkable as us in that way, but I bet they will outlast us given how long they’ve existed.
The thing that always stuck with me about evolution is that we are related to everything. The pup I’m sitting next to is pretty close to me in terms of evolutionary time, the potatoes I ate are a lot more distant, but it is still my cousin, etc. It really makes me feel like I’m part of the world knowing that.
