We have been speaking about all the influences epigenetics has on us. It is really not surprising if you stop and think about it. We are a community of cells that have chosen to survive and evolve as a group. Groups give advantages to the individual cells. The work is more complex and the cells need to divide up the work and do specific tasks. Just like we humans choose a field to become experts in, our cells are one of many types and they specialize in the work of that particular cell type. In such a community cells must be able to communicate with each other to get their work completed. They must be able to defend themselves against foreign attackers like viruses, bacteria, and toxins. The environment affects how they operate and how they do their jobs. Diet, thinking, toxins, air, etc. all play into this.

Why do we eat? We really eat to provide these cells with the missing nine amino acids and some other nutrients. Like any machine, we need to take in raw materials and get rid of waste. The work of the cell is to manufacture proteins from the amino acids. There are many proteins that are made. Some for building foundations like cell walls, others are used to communicate within the cell or to other external cells. The recipe for building these fundamental proteins are in our genes. Genes are basically a coded system indicating which amino acids to use and in what order to assemble them.

It is no wonder that as we seriously change our environment we cause problems in the inner workings of these cells. They do try to cope and adapt but sometimes that causes other problems and we get sick or die. Sometimes they do something remarkable and we adapt to the changes and move on. It is the life and evolution of the DNA that is important not any one species. If we humans were to be wiped out tomorrow, DNA we continue in other species and evolve into another thinking intelligent creature that would be very different from us. Maybe they would better use their environment.
