Document Summary
All we can do in science is collect evidence. These four big molecules are what life is comprised of. The earliest lifeforms (cells) needed to keep everything on the outside out and everything on the inside in. They needed a membrane made of lipids, and instructions on what to do, (nucleic acids), dna and rna. Furthermore, in order for the cell to be able to do stuff, they needed molecules that do stuff, which are proteins. Carbohydrates are a source of energy, as well as from proteins and lipids. C, h, n, o, p are the elements that were critical to life. Lightning and sunlight were the energy sources for the early earth. Rna based living things, rna was the original instructions. Protein misfolding leading to clumps in the brain, causing brain cells to die. Lactose intolerance: people with no mutation that allows them to break down lactase.
