Perhaps at first thought, yes, because mammals, insects and mushrooms are such different things. To put it in perspective though, they share more than 2 billion years of evolutionary history when you look past their last common ancestor. That M1 CPU in your new MacBook is a much mightier beast than the little black ICs in your grandfathers transistor radio, but they both rely on the same fundamental NPN silicone junction property. And that’s only 60 years of evolution.
