Sagan 4

Sagan 4 is a speculative evolution alien planet ecosystem project originally started by Hydromancerx inspired by Carl Sagan's video. Life on this alien planet started from a single-celled organism. It is now populated with many species of flora and fauna all created by artists who love drawing and xenobiology. Submissions for new species take place on the Sagan 4 main forum.

Introduction

Sagan 4 is a planet with conditions similar to Earth. All of its life derives from a single cell, Protosagania. Its major kingdoms are:

• Binucleozoa, an incredibly diverse group in which each cell has two or more nuclei, ranging from fish-like descendants, to insectoid-like fauna to the a wide range of Crystal Flora
• Carpozoa, fauna with wide ranging morphological differences thanks to genomic instability and a tendency towards Earth-like faunal forms
• Mancerxa, the largest kingdom, with a diverse range of fauna descended from green, photosynthesizing ancestors
• Phoenophyta, purple photosynthesizers that include clouds of microbes in the oceans and some of the first flora on land.

...and plenty more! Feel free to dig through the current Ecosystem Page to see all of the intact species and environments.
