Tactics, on the other hand, can get to eyes and brains. Humans can build clocks, but not eyes. Nature can build eyes, but not clocks. Whatever humans build, it has to be built within a lifetime through a carefully planned design. Nature builds its artifacts through millions of years of short-term tactics.
Inheritance involves genes and environment working together.
Jones projects this simple principle into our daily lives. Diseases which are dormant in our genes, for example, may be sparked off by environmental conditions. Diet is as important as genes in the development or the prevention of a disease. And pollution is as important as genes to the development of cancer. And so forth.
