Sagan 4 is an alien planet ecosystem project originally started by [[:User:Hydromancerx|Hydromancerx]] inspired by [http://video.google.com/videoplay?docid=433274581250541893&q=carl+sagan+evolution Carl Sagan's video]. Life on this alien planet started from a [[Protosagania|single-celled organism]]. It is now populated with many species of flora and fauna all created by [[:Category:

Line 25:
Sagan 4 is a planet with conditions similar to Earth. All of its life derives from a single cell, [[Protosagania]]. Its major kingdoms are [[Binucleida]], an incredibly diverse group in which each cell has two or more nuclei, ranging from microbes to the tallest trees, [[Carpozoa]], which tend to be fairly animal-like but include some single-celled and colonial species, and [[Photosagnia]], purple photosynthesizers that include clouds of microbes in the oceans and some of the first flora on land.
The other line of symbiotic Binucleida is the [[Symbiozoa|binucleid worms]], in which the outer shell forms a segmented exoskeleton. The biggest group of binucleid worms is the [[Scutivermida|knightworms]] (descendants of the [[Common Knightworm|common knightworm]])
Carpozoa's biggest lineages are [[Luceremundaria]], which often have colorful bioluminescence and range from fish-like to cup-shaped, and [[Asterzoa]], a diverse group whose original body plan was shaped like a four-armed star.
Line 35:
Asterzoa is split into [[Asterzalia]], many of which have become bilateral swimmers and crawlers, including species with skeletons and formidable jaws, [[Asterstreidia]], radial species, mostly filter-feeders and mostly sessile, many of them shelled, and [[Asterfolia]], which have developed photosynthesis through symbiosis, some of which have become more plant-like and some with more active lifestyles.
There are several additional smaller kingdoms. One is [[Mancerxia]], which currently mostly consists of virus-like microbes. Another, [[Goliathpseudopodia]], consists of large single-celled organisms, some of which are over a centimeter in size. [[Lituswushia]], [[Skarlixia]], and [[Ferrumcarceria]] all metabolize various metals in different ways. The [[Taxonomy]]
'''Fun facts:'''
Life is recovering from a mass extinction involving a crash in oxygen levels and in bioavailable nitrogen.

The largest land fauna ''ever'' was the [[Gigantaurok]], at 5.6 m tall.
The largest partially terrestrial fauna ''currently'' is the [[Lunger]] at two meters long.
The largest fully terrestrial fauna ''currently'' is a three-way tie between the [[Pallazor]], [[Inkblot Notback]], and [[Northern Notback]], at one meter long.
Life has spread across much of the planet, but deserts and montane areas are still relatively barren, as are cave and the deep underground water tables.
