How does a tree (or any plant, really), know to evolve to produce a delicious fruit or a poison berry, a seed inside an impenetrable shell, or invent a type of flying machine, in order to reproduce? (Each of these examples exists in my backyard)

How do they receive feedback about their evolutionary experiments? How do they know it worked/failed. [10]

    I’m not familiar with those things but, if that’s all accurate, aren’t those abilities themselves things that were naturally selected for?

      Plants with more flexible and responsive genetic systems were better able to adapt to changing environments and thus more likely to survive and reproduce, so yeah. However, the basic building blocks of these systems - DNA replication, gene expression, and the fundamental biological processes arose from simpler chemical and physical interactions that were likely governed by principles of self-assembly and thermodynamics. The primary drivers are different at different levels of abstraction and complexity, and there’s dynamic interaction across levels.

      Thermodynamics -> Natural Selection -> Responsive (Epi)Genetics -> Memetics -> Metamemetics (probably?)

      We “boil things down” to Natural Selection or Thermodynamics as is convenient for communication, but the higher levels affect the lower as well. So we can’t really reduce them like that without losing important information.
