Origin of Life There Are Essay

A more controversial theory regarding the origins of life is that it began deep under the ocean near thermal vents. These vents, first discovered in 1979, release extremely hot gases from below the Earth's crust into water that is near freezing (Duke). The mixture of the gas and the temperatures creates a gradient around the vents that is ideal for the formation of organic molecules. There is a flourishing ecosystem around these vents, which is the evidence that first led scientists to postulate that these vents were the sites of the origin of life, but others contend that the extreme temperature of the gas released by the vents would destroy any organic molecules created long before they had time to organize into more complex, let alone living, compounds (Duke).
There are many other theories in addition to these two, and though some might be disproved, it is unlikely that we will ever be able to claim with any certainty how life first came to Earth.
