Life Level

The life level of a world defines (in very broad terms) how advanced native life is on the world. It ranges from no life at all, through simple single celled organisms, to land animals and extensive (Earth-life) conditions.

The life level of a planet is defined in the enum LifeType



The evolutionary path on Earth can be considered to have been something like the following.

base organics originally formed, which were simple amino acids. These gave way to simple organics which were more complex and capable of simple replication, making them the first living things.

The first multi-celled organisms arose in the Metazoan period, are are classed as Metazoa. These evolve into sponges and Algae which become the first 'large' forms of life.

Late in the Metazoan, Plankton, Seaweed (larger, more complex algae) and jellyfish evolve. This created a turning point as bacteria is consumed in large quantities, allowing the oceans to fill with oxygen. That paves the way for simple marine organisms, such as starfish, sea slugs and other complex animals.

The Complex Ocean period is heralded by the arrival of crustaceans, fish and other free swimming vertebrates.

Alien Evolution

The above assumes that things progress in much the same way as they did on Earth. This is unlikely, but easy. The above categories probably fit most evolutionary paths, however the details of each are unlikely to be the same on all worlds - e.g. when grasses first evolve and so on.
