After finding fridgebro many years ago I was inspired to make my own enclosed ecosystem that would evolve and become unique. I'm going to start small with terrariums, and place each one in an increasingly larger enclosure. Any ideas on how to create a unique enough environment? So fare I have decided on ants/bugs that breed fast for faster generations, and maybe altered light cycles and temperature underground, mirrors, chemicals. Of course ants are used to the underground so maybe something else. I guess I'm asking how to accelerate evolution.
