Questions and Answers

What is chemical evolution theory?

Chemical evolution theory, also known as abiogenesis, posits that life on Earth originated from non-living matter through a sequence of chemical reactions.

What is another name for chemical evolution theory?

Abiogenesis or prebiotic chemistry.

What are the complex organic molecules that formed spontaneously in the early Earth's environment?

Amino acids and nucleotides.

What did chemical evolution theory suggest about the transition from non-life to life?

That complex organic molecules eventually gave rise to the first self-replicating entities. Signup and view all the answers

What is a protogenome?

A protogenome is a hypothetical mutable primary unit that is capable of reduplication, is held to have differentiated from non living matter and is regarded as a precursor of living beings. Signup and view all the answers
