They must evolve to survive the harsh and ever changing conditions of their environment.
In time their descendants will branch off into different species, predators and prey, ones that swim, fly, burrow… but right now they share a shallow primordial pool.
You can tell me what you want to see them become next, or take it upon yourself to evolve one down your own path. Anyone can add a new feature, evolving your design further and further away from your intentions. Try to be incremental with your evolutions.
After a few pages I’ll make a big family tree, so we can look at where we started and what we end up with.
