How Evolution Connects All Life on Earth

One Origin, Endless Forms: All living things—from bacteria to blue whales—descend from a single ancient ancestor billions of years ago.
DNA: The Common Thread: Every organism uses the same genetic code, proving life’s shared foundation at the molecular level.
The Tree of Life Is Real: Evolution links all species through branching lineages, each one tracing back to life’s earliest roots.
Shared Genes, Shared History: Humans, birds, and even trees share portions of the same DNA—a record of life’s interconnected story.
Diversity From Simplicity: Through mutation and selection, evolution turned simple single-celled organisms into Earth’s dazzling variety of life.
Fossils Confirm the Flow: Transitional fossils show how species change gradually, connecting the ancient to the modern world.
Molecular Time Travel: Genetic comparisons reveal when species diverged—allowing us to map life’s history with remarkable precision.
Cooperation Across Kingdoms: Symbiosis—like plants and fungi or humans and gut bacteria—shows how connection drives survival.
The Web, Not a Ladder: Evolution doesn’t rank species—it intertwines them in a vast, ongoing network of shared ancestry.
We’re All Part of the Same Story: From the smallest microbe to humankind, evolution links every creature as part of one living, evolving Earth.
