Answer 1

The first person who proposed that small organic molecules could have arisen by chemical evolution was Aleksander Oparin.

Explanation:

Aleksander Oparin proposed the concept of chemical evolution, suggesting that life originated gradually from simple organic molecules forming under the primitive Earth's conditions in a reducing atmosphere. His theory laid the foundation for later experimental verification by scientists like Stanley Miller and Harold Urey, who demonstrated abiotic synthesis of organic molecules in the lab.
