I know I am a living system because.....

Wow! Crazy how things can become not so black and white when you begin to look into what is considered a living thing. According to NASA, all living things share a carbon based chemistry, depend on water, or leave behind a fossil with carbon or sulfur isotopes that point to a past metabolism. Scientists struggle to define "life." From what I have read so far, it seems like something could be considered living and have certain characteristics of life, while others may be "alive"  and have slightly different characteristics. Crystals are interesting. They can grow and respond to stimuli but lack a nervous system. I believe there are many different forms of life and we can see things as living that are not what we would expect. In a Native American perspective even rocks are infused with spirit, is that a living thing?

  1. I think that if it exists in our biosphere and isn't man made, that the item in question is, indeed, a part of a living system. Rocks are apart of the living planet for sure!
