Where do scientists believe chemical evolution occured?

Answer 1

Answers to this question vary: there are a number of hypotheses on the first origin of life. The leading thought is that the first molecular replicators came into existence near thermal vents on ocean floors, in deep caves, or in shallow waters near volcanoes.

Some hypotheses include the possibility that the molecular building blocks of life may have originated in space. Spectrographic analysis of interstellar gas clouds shows that they contain organic compounds. Laboratory simulations of primordial conditions on the planet Earth also show the formation of organic compounds including amino acids, a crucial ingredient for the evolution of life.

Answer 2

In the ocean or in deep caves.

There are various hypotheses regarding the origin of life. Most of them have key steps taking place in deep waters, near thermal vents; or in water-soaked crevasses and cracks deep in mineral rock. Less likely candidates are shallow ponds - although some of the complex organic molecules involved in abiogenesis may have formed in such ponds.

Answer 3

Scientists believe that chemical evolution occurred on early Earth, likely in locations such as hydrothermal vents in the deep sea or shallow pools of water on land. These environments provided the necessary conditions for simple organic molecules to form and evolve into more complex compounds, eventually leading to the origin of life.

Answer 4

In the ocean or in deep caves

Answer 5

Probably in tidal pools.
