We are human beings. Great thinkers! The only animal to shape their environment and build technologies. We have evolved a lot since the first mammals took foot but we are biological machines. Our cells are independent of each other but communicate with each other. The body gives a place to build organs, muscle and brain that helps provide each cell what they need to do their job. They have many signals as inputs (some are epigenetic signals). They must decide to accept or reject inputs based on their environment. Muscles cells will always build more muscle cells (the same is true of each different type of cell in our bodies). Over 10 trillion of these tiny thinking machines make us human. Other animals have nearly the same DNA as we do, similar brain structures. Their cells do similar things but they did not evolve into humans. Our epigenetic signals is what makes us human! Like a computer with a common Intel chip set, we can have simple programs or unbelievably smart ones. The difference is the software (how the Intel chip set is “played”). Our DNA is like the chip set and it is “played” by epigenetic signals.

What are these signals? They are hormone, nutrients from the food we eat, signals from our brain based on how we think, etc. Is your epigentic signals playing Chopin or chopsticks?
