Charles Darwin and some modern
Charles Darwin and some modern scientists think that life started all on its own, it sort of just...happened, spontaneously. It’s called chemical evolution (aka Abiogenesis). They say it started with chemicals forming building blocks, and then combining into polymers like DNA and RNA.
The next step toward life would be CELL MEMBRANES. All living things are made of cells that are surrounded by a cell membrane, life simply cannot exist without membranes.
Origin-of-life researchers claim that cell membranes are easy to make and that they have demonstrated this in the lab. They point toward experiments where these molecules called “phospholipids” (or more generally “amphiphilic molecules”) are placed in water and they form into a spherical shell–kind of like a cell membrane–all on their own. Wow!
But is it really the case that cell membranes are so easy to form? Let’s take a look more closely….
