What answers to all these problems?

“Why water boils at a 100°C and methane at -161°C; why blood is red and grass is green; why diamond is hard and wax is soft; why graphite writes on paper and silk is strong; why glaciers flow and iron gets hard when you hammer it; how muscles contract; how sunlight makes plants grow and how living organisms have been able to evolve into ever complex forms – the answers to all these problems have come from structural analysis” - Max Ferdinand Perutz
