Ages of sand: douglas adams divided the earth"s history into four ages, each defined by a discovery of a new use of glass. The first age of sand was a macroscopic view of the universe, giving it various general principles, laws, classifications. The second age of sand was a microscopic age, in the sense that lenses were made to look deeper into the world. The third age of sand was that of silicon, as in silicon chips. This gave the world computers and the ability to do calculations extremely efficiently, and further understand how life works. The fourth age of sand is that of fibre-optics, communication gone wild. Cell phones, internet, and such enable the entire world to communicate with each other instantly. Analogy: in terms of analogous structures, they are structures of two different species that perform similar functions, but come from different origins. This can be because of adaptations to similar environments.
