Yeah, there’s never a hard dividing line between a species and its immediate predecessor. Merely a gradual chain of mutations that eventually results in distinct populations. If those populations can’t successfully interbreed even if transported to meet, they’re different species. The definitions for asexually reproducing organisms are even more fuzzy. This concept that taxonomy doesn’t have fixed divisions confuses a lot of anti-evolutionists.

The proto-chicken was a mutant Red Junglefowl. Just like a proto-dog was a mutant wolf.

The business is genociding the out-group. It is just the cost of doing business to them.

NixOS + Home Manager user here.

I run in an opt-in state config. / is tmpfs. /home is tmpfs. /boot and /nix are real filesystems. At boot, the EFI loader reads the configuration from /nix/persist/etc/nixos/flake.nix, symlinks all the programs and configs into / and /home, and startup proceeds as normal.

That means nothing persists across boots unless I add it to my config. Cruft doesn’t accumulate in hidden areas, it’s all in my config. That keeps things fast, makes management easier, and makes troubleshooting easier.
