question 1 - 15
one of the accepted scientific hypotheses describing the origin of life on earth is known as chemical evolution. during chemical evolution, which of the following events would need to occur first for life to evolve?

• onset of photosynthesis
• origin of genetic material
• synthesis of organic molecules
• formation of the plasma membrane

Explanation:

Chemical evolution involves the formation of organic molecules from inorganic substances. These organic molecules are the building - blocks for life. The origin of photosynthesis, origin of genetic material, and formation of the plasma membrane are later steps in the development of life. The synthesis of organic molecules is a crucial first step for life to emerge during chemical evolution.

Answer:

synthesis of organic molecules
