How to play:
Take one of the images below and make a small change to evolve the creature. You can change one aspect of the creature to a small degree. Add a sciency sounding name to the creature and write up a bit about it. Lastly, make sure to write the name of the creature it evolved from. You don't have to use the most recent iteration of a creature, in the case you want to branch off, so letting me know what creature you started with is important here. You can also change the background if the creature moves to a new location as part of your evolution.
Rules:
(1) Only slight changes. If you're adding a new part, it should be pretty simple. If you're editing an existing aspect, it shouldn't be too far from the previous iteration either. For example, if its a creature with feet and you want webbed feet, that's totally cool. If its a creature with no feet or limbs, you can't just jump to giving it full limbs with webbed feet.
(2) Don't edit the same creature twice in a row. You can a creature once two other people have edited that creature. This is on a per creature basis, so for any of the four lineages, as long as there are two other evolutions between your post and your last post of the same creature, it's cool. Gotta let everyone get in on the evolution action.
(3) Use good save files. PNG is my favorite for things like this, but I think JPEG would also work. That's not really my department. Just make sure its a quality upload so the images don't degrade as the game goes on.
(4) Don't argue, especially with the GM. Discussion about the evolutions and all that is highly valuable, bad attitudes are not. If I veto something, it's veto'd.
(5) Have fun and be creative.
Primus Fishicous
A common green aquatic creature. It's body is shaped to help it move through water, but lacks any real specialization.
Primus Plantimum
A small photosynthetic growth. It has tiny roots and lacks much structure.
Primus Orangitha
A small orange and pink thing. Fossil records have yet to reveal whether it is a plant, animal, or something else.
Primus FungoniaA small fungi with a cream colored stalk and bluish cap.
(My notes and names are all pretty short and nonspecific. Player posts should be a lot longer and detail how the adaptation is useful for the creature. Mine are fairly short and open ended because they're the first ones and also so that the can be taken in any direction. Ready, set, go!
Lastly shout out to Lord_lemonpie. He ran the first version of this game that I ever saw, iirc.)
