 The evolutionary path on worlds can be very different in the details, but the initial steps are broadly similar at the high level. Diversity really comes in beyond the //Aerobic// stage. The evolutionary path on worlds can be very different in the details, but the initial steps are broadly similar at the high level.

 [[.:commodity:organicchemicals]] originally formed, which were simple amino acids. Most worlds with liquid water will form basic organic molecules like this, but few progress any further. Such worlds have an [[life:Organic]] classification. [[.:commodity:organicchemicals]] originally formed, which were simple amino acids.

-[[.:commodity:prokaryotes]] are the first living organisms, and include bacteria, as well as earlier forms. On many worlds, Prokaryotes is as far as it gets, and it can take billions of years to evolve anything more complicated. The presence of Prokaryotes are a marker for [[:life:Archaean]] worlds.+[[.:commodity:prokaryotes]] are the first living organisms, and include bacteria, as well as earlier forms.

-Over time, colonies of singled celled organisms may form something similar to [[:commodity:algae]] or [[.:commodity:slimemolds]]. These may start producing oxygen as a by-product.+Over time, colonies of singled celled organisms may form something similar to [[.:commodity:algae]] or [[.:commodity:slimemolds]].

-[[.:commodity:protozoa]] are multi-celled organisms, and are generally the sign of [[:life:Aerobic]] worlds since they generally don't form until there is sufficient oxygen in the environment.+[[.:commodity:protozoa]] are multi-celled organisms, and are generally the sign of [[.:life:Aerobic]] worlds since they generally don't form until there is sufficient oxygen in the environment.
  
 [[.:pcl:EoGaian]] worlds are pre-Aerobic, with a mostly methane atmosphere. Once the life classification changes from //Archaean// to //Aerobic//, then terrestrial worlds are classed as [[.:pcl:MesoGaian]]. [[.:pcl:EoGaian]] worlds are pre-Aerobic, with a mostly methane atmosphere.
