  • 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.


  • In our effort to disillusion people of the idea that evolution has a purpose or conscious hand, we over-simplify things, though. Plants actively (but not consciously) shape their own evolution through complex molecular and genetic mechanisms. They can respond to environmental stresses by altering their DNA methylation patterns, potentially priming future generations for similar conditions. Plants also engage in niche construction, modifying their surroundings in ways that influence their evolutionary trajectory. For instance, they can change soil chemistry through root exudates, creating new selective pressures for themselves and their offspring. Plants participate in intricate co-evolutionary relationships with pollinators, herbivores, and other organisms. These interactions create dynamic fitness landscapes that drive reciprocal evolutionary changes. While not “inventing” traits in a deliberate sense, plants possess sophisticated genetic tools - such as whole genome duplications, transposable elements, and adaptable gene networks - that allow for rapid evolutionary innovations. These mechanisms enable plants to continually adapt and evolve, even without conscious intent or direct feedback.

    Claude, re-write my post.

    <Claude> Sure thing boss!

    Generative AI fascinates me, and I use it frequently for both work and leisure. This photo, however, is the first to make me feel a twinge of sadness, as it reminds me that I now have to question the authenticity of everything I see.

    Then I recall that even traditional photographs often undergo extensive post-processing, which somewhat alleviates my concern. To distract myself, I create an AI-generated video of the river flowing, momentarily forgetting my worries.

    However, I can’t help but notice that many of these AI generations are of poor quality. Generative AI is simultaneously wonderful and troubling - a double-edged sword of technology.

    Despite these mixed feelings, I must admit this is a beautiful photo.

    I love generative A.I. I use it all the time, professionally and recreationally. This photo is the first to make me sad that I have to question the veracity of everything now. Then I remember the amount of post-processing a photo like this usually goes through and feel less sad. Then I make an AI video of the river flowing and forget what I was worried about. But all these generations are kinda trash. Such wonderful, terrible things. Beautiful photo, though.
