The Origins of Life on Earth
2:57:41 - 3:04:54 (07:13)
The emergence of life on earth required two different pre-life forms, the peptide world and the RNA world, and it is considered a planetary phenomenon.
Clips
The interaction and emergence of life is a planetary phenomenon based on available chemistry and the ecosystem.

The structure of life across time has always been multi-scale, ranging from global climate changes caused by individual mutations, to the independent origins of interacting living things at the largest and smallest scales mediated by life.

The origins of life on Earth potentially involved two distinct forms, the peptide world and RNA world, but the chemistry of alien life would likely be more cohesive due to causal chains overlapping.

Summary
The origins of life on Earth potentially involved two distinct forms, the peptide world and RNA world, but the chemistry of alien life would likely be more cohesive due to causal chains overlapping. The idea of a "shadow biosphere" on Earth containing alternative biochemical mechanisms has yet to be fully explored by scientists.
