Life. It begins infinitely small with chemical processes and structures that hold every piece of information that determines life. Our DNA tells each cell how to specialize, and soon the synapses in our brains are firing and governing every system in our bodies. Every process that sustains life. Ah, the human brain. It regulates but also thinks and dreams, and is inspired to learn and to understand. So here we are, explorers of life, but not just of our own, we are interconnected with and affected by every other living thing. We are surrounded by life. Plants, animals and other organisms that are too small to see with the human eye. Together we share this planet called Earth. Teaming with life. Interdependent creatures in a perfectly balanced environment. This is our laboratory. Biology. The science of life.
