The laws of physics bind together the most fundamental constituents of matter electrons and quarks into stable structures called atoms. Atoms themselves are subject to a new set of rules … pushing and pulling one another, and combining into new forms molecules governed by the laws of chemistry. Simple molecules of water and carbon dioxide, consisting of only a few atoms, can combine and interact in ever more complicated ways … building more and more complex structures … clumps and chains and rings. The rules of chemistry are universal. The same kinds of amino acids that we find in our own bodies can also be found in the cold depths of space. At some point, very large and complex molecules become capable of something new. DNA molecules make copies of themselves. The chemical metabolism inside of a cell produces and stores energy … energy that can be used for motion… and reproduction. The raw material of chemistry has given rise to a new kind of complex behavior one that we call life. Large multi-cellular organisms involve a whole new class of …
