Common Ancestry

Every living thing — you, a blade of grass, and a giant whale — is part of one giant family tree. If you go back far enough in time, we all share the exact same great-great-great... grandparent. We are all made of the same "Lego bricks."

You aren't in the world; you are the world. Every person you meet is a distant cousin, and every animal is a brother or sister in the long story of life.

Common Ancestry is evidenced by Molecular Homology, specifically the near-universality of the genetic code (DNA/RNA) and highly conserved proteins like Cytochrome c. This links to Phylogenetics, the study of evolutionary relationships. It suggests a "Singularity of Life," connecting biology to Information Theory (the transmission of a singular code through time).

SOUND: Your heartbeat. Almost every mammal has a heartbeat that follows a similar rhythm.

SMELL: The scent of rain (petrichor). It triggers a deep, ancient feeling because water is life for everyone.

TASTE: The taste of sugar. Almost every living cell on Earth uses sugar for energy.

TOUCH: Press your palm against a tree trunk. Both you and the tree use water and sunlight to grow.

SIGHT: Look at your five fingers, then a cat's paw or a bat's wing. The bone shapes are almost identical.

BODY: Close your eyes and feel your lungs expand. That need for oxygen is a trait you share with fish using gills.

One Giant Family Tree

Every living thing — you, a blade of grass, and a giant whale — is part of one giant family tree. If you go back far enough in time, we all share the exact same great-great-great... grandparent. We are all made of the same "Lego bricks."
