I have, at least a little. After I was asked to give a talk on our immense family tree of all life on Earth, I realized that this was a powerful idea, one of the biggest ideas to be shown by science (and yes, the essence of this idea has already been a main part of many indigenous spiritualities for thousands of years before Darwin and Wallace provided evidence for it). So I wondered, if I were to make a list of the top 5 life-changing ideas shown by science, what would they be? In just a few dozen seconds, idea after idea came to mind! Here is that very rough list – “top 5 ideas”? That got blown out of the water quickly!
- We are starstuff (stellar nucleosynthesis)

- There is no magic life force (“élan vital“)
- Heliocentrism
- Earth is a globe
- The sun in a star (and the stars are suns)
- Newton’s deterministic Laws of motion
- Invisible colors (the electromagnetic spectrum)
- We are all one family tree
- Age of the earth/geology
- Chemical cycles (water cycle, oxygen cycle, etc.)
- How the brain works
- Both sperm and egg needed for pregnancy
- Milky way is our galaxy
- Big bang/the universe had a beginning
- Nerves are electrical
- Electricity exists (what is lightning?)
- Disease caused by microbes, not demons
- Air exists (plenty of people don’t fully realize that there is material in our face, etc.)
- Sound has a speed
Whoa, I better stop! I’m sure I missed some big ones, but this is already well beyond my initial thought of a few ideas. What is your list like? Each of these (and more like them) deserves a large place in my life, and maybe even our society – much more so than a Superb Owl (who is also part of our Family Tree), I think. I can’t wait to focus on each of these – but for now, we have an opportunity to revel in one of them – our immense Family Tree of All Life on Earth!
Imagine being in a family of marvels – an aunt who discovered DNA, a nephew who can fly, a cousin who can swim as fast as Olympic swimmers, and more. It’s real! Science shows that all life on Earth is our literal family – and that connection fills me with joy and awe. It also spurs me to action. Our Earth is my body as much as my arm or leg, making climate change a direct threat to so much that I love. Join me on February 12th, discovering the biology which connects us all – including all mammals, all animals, and all life on Earth!
This Monday, February 12th (which is Charles Darwin’s 215th Birthday!), I’ll be leading a discussion of this wonderful gift from Darwin at the Earth Based Spiritual Action Team meeting, 5 pm Pacific Time (8 pm EST). Here’s the information to join us!

Starstuff, Contemplating: We are assemblages of ancient atoms forged in stars – atoms organized by history to the point of consciousness, now able to contemplate this sacred Universe of which we are a tiny, but wondrous, part.

Dr. Jon Cleland Host is a scientist who earned his PhD in materials science at Northwestern University & has conducted research at Hemlock Semiconductor and Dow Corning since 1997. He holds eight patents and has authored over three dozen internal scientific papers and eleven papers for peer-reviewed scientific journals, including the journal Nature. He has taught classes on biology, math, chemistry, physics and general science at Delta College and Saginaw Valley State University. Jon grew up near Pontiac, and has been building a reality-based spirituality for over 30 years, first as a Catholic and now as a Unitarian Universalist, including collaborating with Michael Dowd and Connie Barlow to spread the awe and wonder of the Great Story of our Universe (see www.thegreatstory.org, and the blog at evolutionarytimes.org). Jon and his wife have four sons, whom they embrace within a Universe-centered, Pagan, family spirituality. He currently moderates the yahoo group Naturalistic Paganism.
