Okay so in a nutshell @NightBr1nger and I had a discussion on discard last night, and we both agreed that in practicality, there is a bottleneck on diversity. Concurrently, we see a trend where for each creature there is only one descendant, which limits diversity in multiple ways. So we decided at the end of each phase we have to get rid of a third of creatures considered uncreative that'll rounded up and made extinct to keep diversity up. if you want that at a lesser scale, you can help out by making multiple descendants from one creature so we don't round up as much to be disposed.
This is @-Neovenator- speaking by the way
