Except that horizontal gene transfer happens.
Genes are not always gained from ancestors

In a way. I mean we know it exists, no one would reasonable deny it, but the exact mechanism are still debated. How much is beneficial adaptation, how much is genetic drift for example. But the common ancestry is as common sense as that an apple will fall to earth

bacteria and some others, preparing for horizontal gene transfer: “im about to ruin man(kind)'s whole career”

Yeah the real issue in a way is that there’s just so much evidence of evolution happening that it’s hard to find a single shared pattern to study

The pioneers in some fields are calling for studying (or renaming it) INvolution as opposed to evolution, as it has much to do with involved interactions with other life forms (bacterial, fungal).

I thought it was pretty well accepted that it’s basically “Genetic defects happen, sometimes they don’t prevent reproduction and pass down to the next generation, then it’s a lottery, maybe it will last, maybe it won’t, maybe it’s beneficial, maybe it isn’t 🤷”
Maybe at some point an human was born with knees that would never wear out but they died in before having the chance to reproduce from being eaten by a tiger, we’ll never know!
