"Devolution" is definition in biology. It's not a concept. It means the losing of previously evolved structures. As a definition it can't be incorrect, it can only be shown to exist or not it exist. It happens frequently, as a matter of fact. Again, the 2nd law doesn't apply in any way that it doesn't already apply to any other aspect of life. I don't know what this means. Of course it's physical. Organisms are made, destroyed; they eat, make new organisms along the way. There's an underlying molecular biology to it all, but all the processes at every level are physical.To me, evolution is a physical process, but I think you have a different perspective.

Again, the 2nd law doesn't apply in any way that it doesn't already apply to any other aspect of life. There is no "devolution" which is not more generally understood as "evolution". It can be confusing for people to talk about something devolving because it implies a hierarchy to evolution, and furthermore that we can "go backwards" down this hierarchy. In saying that evolution is always progressing, I'm just stating a physical fact. We can't become our parents or ancestors. To do so, there would have to be some process that remembered how they were and undid all the changes to our genomes that accumulated over time. The only way that we may begin to look like our ancestors is through the continued process of evolution.
