Just the other day I asked Chat GPT to describe an alien planet so I could make a Spec Evo project from there, but it also described its biology.
In this project I will try to imagine the evolution of the strange creatures that the machine created

Era A
Eukaryotes initially fell into three groups: photosynthetic vegetation based on H, C and B, photosynthetic animals based on CO2 and BF3, and true animals
Photosynthetic animals are divided into specimens with radial symmetry and asymmetric, and true animals have bilateral symmetry
During this period plankton adapted to "migrate" to the light hemisphere through rapid death and short lifespan. This prolific food source turned the seas red and enabled an equivalent of the Cambrian explosion
Photosynthetic animals adapted as plankton, echinoderms, filter feeders, etc.
Some examples are the eopolypodia (filters and scavengers with radial symmetry that move along the seabed using eight tentacles), the tunicadomimia (asymmetric organisms with a complex life cycle, first as a planktom and then as a sponge, which also have a cord primitive nervous system), and the tetravertichia (radials with four vertices and a symmetry between radial and symmetrical, which float in the water driven by currents, feeding on plankton)
The biodiversity was so rich that the sea floor was covered by a multitude of sessile organisms, forming a continuous moss, food for many true animals.
On land the plants took their first steps. First as beaks without even roots, but later as trees, grass and cycads with seeds.
