Only biological systems exhibit quantum activity or quantum computing. It may actually be our most significant common origin when asking what common ancestor made us human is futile. Understanding that our ability to process quantum activity or to process Information in a way that transcends physical materiality and strictly biological function is actually what gives us life. If we think of the building block or lego analogy, rocks are Composed of regular arrangements but they did not build arrangements. Every cell Has quantum activity it's very clear from the cell structure how it insulates the nucleus even the cytoplasm is arranged such that it provides excellent shielding. It's actually a faraday cage for quantum activity which has now been shown. So what does that mean well it's not quite as magical as you may think it simply means that cells can communicate in ways that wouldn't be possible strictly speaking through physical processes. How do cells coordinate and communicate with each other how do they determine how they regrowing all of this could not happen in a strictly physical sense it has to transcend, say chemical markers or that kind of process. Furthermore given the time uh given the time/delay involved In physical communication how could a heart ever beat regularly if not for that kind of trans physical coordination through quantum activity?
