Question

Using sources other than your textbook, discuss the factors that made prehistoric Earth a place for 'life' to begin, how did water play into these factors, why is water so important for life, what were the earliest organisms, and what is the heterotrophic hypothesis and how does it describe the origins of life.

This is for an oceanography class

Answer 1

Life started on earth 600 million after its formation, the planet has cooled down from its molten state,developing a solid crust and oceans created from water vapor in the atmosphere.

The study of the origin of life on Earth or, more specifically, how life on Earth began from inanimate matter, is technically known as abiogenesis (as opposed to biogenesis, which is the process of lifeforms producing other lifeforms, and as opposed to evolution, which is the study of how living things have changed over time since life first arose).

The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

The cooling down of the primordial world to the point where the outgassed volatile components were held in an atmosphere of sufficient pressure for the stabilization and retention of liquid water.

Every organism requires water for survival on this planet.
