Did chemical evolution precede animal evolution?

Answer 1

Yes. Animals are composed of chemicals. Chemical evolution typically refers to stellar nucleosynthesis, the creation of elements by nuclear fusion in the cores of stars, and the synthesis of elements heavier than iron via star bursts--supernova.

Biochemical evolution would refer to the formation of more complex molecules, such as the spontaneous generation of amino acids from less complex molecular arrangements.

Answer 2

Yes, chemical evolution preceded animal evolution. Chemical evolution refers to the transition from non-living molecules to simple living organisms, whereas animal evolution specifically refers to the development and diversification of animals from simpler to more complex forms. Chemical evolution laid the groundwork for the emergence of early life forms, including the common ancestors of animals.
