The Great Tree of Life: Tracing Our Evolutionary Roots

All Life, One Tree: Every organism—from bacteria to humans—branches from a single trunk of shared ancestry.
DNA as the Map: Genetic code is the ultimate guide to the Tree of Life, revealing surprising family ties across species.
The Three Great Domains: Life divides into Bacteria, Archaea, and Eukarya—three vast kingdoms that shaped every ecosystem on Earth.
Roots in the Microbial World: The earliest branches belonged to single-celled pioneers that learned to eat, move, and multiply.
Branching Through Time: Evolution works like a growing tree—old limbs split, new species bud, and extinct ones leave fossil scars.
Hidden Connections: Mushrooms are closer to humans than to plants—a reminder that the Tree of Life holds unexpected kinships.
Tracing Our Own Line: From fish to reptiles to mammals, each ancestor added a ring to the story that led to us.
Genetic Time Travel: Comparing DNA across species lets scientists trace billions of years of evolutionary history.
The Web Beneath the Tree: Life’s story isn’t a straight line—genes jump, merge, and trade between species, weaving a living network.
We’re Still Growing: The Tree of Life continues to branch as evolution writes new names on its ever-expanding leaves.
