Phospholipids are made up of fatty acids, glycerol, and phosphate.
If you're referring to the structure of a phospholipid, they are composed of a water-loving (hydrophilic) head and a water-fearing (hydrophobic) tail. The tail is made up of long chains of hydrogen and carbon molecules as well.
Macroevolution studies how taxonomic groups above the level of species change. Its evidence draws frequently from the fossil record and DNA comparisons to reconstruct how various organisms may be related
