We had the tall stride thing going, we had the super-endurance thing going already, we had gotten good at tool-use like many other primates, in that we could use sticks and rocks to beat things and poke things, just like modern chimps and apes. (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. Moving our camps 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.
Not to mention, we’re the only creature that chooses when to reproduce. We used this foresight to plan our futures and our families. This is a massive changeup from how nature has handled reproduction. For the vast majority of life on Earth, breeding is just this thing that “happens” at certain points and everything leads to that event, and nothing really has control over how that event plays out.
Breeding is still a big deal for us, just look how horny we all are, but we decide when we’re going to have babies, and while it doesn’t seem a big deal here and now, it was a game changer when we were migrating packs of hunter-gatherers, following the seasons and the herds of animals.
Our story of how we got here is without question the most fantastic story ever. You are the product of over four and a half 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 that sometimes lasted for millions of years.
So now you made it, your billions of generations of ancestors secured your survival against all odds, whatcha gonna do with it?
