Phosphorus, oxygen, and microbes cooperate in a delicate balance that sustains our productive biosphere. How did they come to interact?
Without foresight to solve heterochiral incidents, a primordial cell would quickly perish even if, against all odds, it began homochiral.
Epigenetic mechanisms are ubiquitous in biology. Because of epigenetics, organisms with otherwise identical genes (e.g., twins) can be quite different.
Nowhere do these scientists explain how bacteria invented magnetotaxis and encoded it into their genes.
Miller and Luskin discuss fruit flies, finch beaks, stickleback fish, mutational hotspots, phenotypic plasticity, and the gravity well model.
