To understand how multicellular life began, it is important to first briefly explore how life began at all. According to geological dating methods, the Earth is roughly 4.5 billion years old, and roughly 4 billion years ago it accumulated substantial amounts of liquid water. Liquid water is a necessary component for life as almost all chemical reactions in living things take place in aqueous solution.
Around 4 billion years ago, when water began to accumulate, it set up the conditions needed to produce micelles and lipid bilayers. The amphipathic (hydrophobic and hydrophilic regions) of lipids caused them to form both micelles and liposomes. Liposomes are the precursors to cells and are important because they provide a barrier between what is inside the liposome and what is ...
This solution provides a summary for how multicellular life originated on Earth, describing the evolution from the first unicellular organisms on Earth to more complex organisms.
