9/ Most plausibly the active collaboration of some of the earliest lifeforms for their mutual survival led to their merger and resulted in the divergence of life into different branches, most of which ramified further into increasingly complex species.
10/ The increasingly vast number of species spread across the surface of the planet to occupy habitats conducive to their particular means of maintaining their existence and reproducing themselves. They formed a biolayer above the inanimate geosphere.

11/ Competition for resources, damaging genetic mutations, and rapid environmental change resulting in the loss of conducive habitat caused the most dominant pattern among living things, namely the extinction of species.

13/ The animal branch was characterized by mobility, sexual reproduction that increased complexification, and a developing centration of a nervous system for sensing and responding to internal and external stimuli.
