<b><u>Cells emergence in sea water</b></u> | <b><u>Cells emergence in sea water</b></u> | ||
As the youtube channel Kurtzgesagt says, <i | As the youtube channel Kurtzgesagt says, <i>“a cell is a piece of the dead universe that separated itself from the rest, so it can do its own thing for a while”.</i><ref>source: https://www.youtube.com/watch?v=QImCld9YubE&t=63s</ref> Here, “the dead universe” would be sea water, and what separates the cell from it would be its membrane. This “skin” main structure is the “lipid bilayer”, that has been shown to be able to emerge spontaneously, under certain conditions in water containing phospholipids, that are just some kind of fat. If you ever made mayo or other types of sauce, you would know that fats can’t mix with water, and are therefore useful for the cell to separate itself from its watery environment. This is only one of the scientific experiments that tries to demonstrate how life could have emerged in the “primordial soup”, 3.5B years ago. In fact this hypothesis of life emerging in oceans water, called “abiogenesis”<ref name="wikisource" />, is widely accepted by scientists, but its mechanisms stays poorly understood. | ||
