How Early Cells Got Their Start

Early cellular life began under the harsh conditions of early Earth, where simple chemicals could form more complex organic molecules. Experimental evidence supports the idea that RNA nucleotides, amino acids, and lipids could arise spontaneously in this environment. Volcanic activity, strong UV radiation, and an atmosphere ...

One of the several hypotheses suggests that the earliest forms of life likely originated at hydrothermal vents on the ocean floor.

Hydrothermal vents provided heat, chemical gradients, and inorganic compounds, such as hydrogen and hydrogen sulfide. This environment might have facilitated the abiotic synthesis of organic molecules, includin...
