Exploring the sciences of cosmology, biology and genetics help us to better understand the deep human connection to nature. Cosmologist Brian Swimme explains how being human is an extension of the original energy that emerged from the eruption of light that occurred 13.7 billion years ago in our universe. As the universe expanded and cooled the actual components of our bodies emerged. These components exist throughout the planet in various species and forms ranging from water to rocks. Biologist Lynn Margulis discovered that all complex life developed from an original symbiosis of four different bacteria. Three of these bacteria were incorporated into the first nucleated cells, and the fourth was the one that gave them mobility. These nucleated cells eventually fused into more complex forms including plants, fungi and animals. Biologist Edward O. Wilson has described how all higher eukaryotic organisms, which are organisms containing one or more cell with visibly evident nuclei and organelles, from flowering plants to insects to humanity are thought to have descended from a single ancestral population that lived about 1.8 billion years ago. A genetic comparison between humans and other primates highlights the similarities. The typical human protein has accumulated just one unique change since chimps and humans diverged from a common ancestor about 6 million years ago. Jane Goddall and Mark Beckoff explain that we share 98.7% of our genes with chimpanzees, 97.7% with gorillas and 96.4% with orangutans in their book "The Ten Trusts." Geneticist David Suzuki speaks about how humans literally are our environment. The air that we breathe; the water that we drink; the sun that generates energy in plants that we eat; and the soil that grows these plants; all exist as elements within our physical bodies. Johan Galtung reminds us of how the atmosphere, hydrosphere, lithosphere, micro-organisms and plants all come together for the successful operation of photo-synthesis, which in turn is the basis for the food chains on which we all depend. The components of nature all exist within us. Elisabet Sahtouris explains how humans see through their eyes that plants, animals and even rocks are separate, but if we look into a magnifying glass all of nature exists in an energetic molecular dance of chemical reactions and recombinations. We are connected to all aspects of nature, and its preservation is critical to our very survival.
