Thanks! You can already doth both from the pause menu :)
lol yes I just found it. I came here to retract my suggestion :P Thanks for your reply though!
Ok another idea then: maybe you could have an option to let bones slowly evolve in length especially when most creatures are within a few percent fitness from each other.
also it would be fun if you could move the joints design around between generations :P
do not exist a way to change the total population per generation, some times is better start with a huge population, and star to lowing the number of population, for exmaple, i started a spider with 1000 population per generation, using 40 per batch. now after 500 generations i would like low the population and speed up my simulation, becoune now the spider is close of the best way to run.
