I'm pretty sure everyone knows how to do these but anyways let me tell you how its done.
You chose a creature and add one change to it each post to better help it survive in the unforgiving world. No adding 'horns because dey look kul lol'
Or 'Magic because I dunno lol' every evolution has to have a meaning behind it.
That said you can change a creature regardless if it is the most current one. You can add adaptations to anything along the evolutionary 'chain' and I will add events as I please and some creatures may go extinct and you are unable to evolve them while entirely new ones could pop up. Lets get it on.
Posting creatures now.
Oh shoot complications came up wait a sec
The Kreen. These plant like organisms feed off of light and turn it into simple sugars that their primitive bodies can use
The Oola, masters of the sky. this canabilistic race flies around, eating all other Oola in sight
The Wyrium, an aquatic worm like creature that swims around, eating all kind of floating detrius.
and lastly the Gibbyal. these ambush predators bury themselves in sand at the bottom of the shallows and when something passes in front of them they snap it in their jaws and pull it under
The Gibbyal developed neurotoxin in their pincers

Wyrium evolves serrated leech like teeth in order to chew down biological debris
>>1313902
How big are all these creatures roughly? I assume if im allowed serrated teeth I can now scavenge small corpses (with enough wyrium) and eat scraps of plant and bio matter
