The DNA Evidence That Proves Evolution in Action

DNA: Evolution’s Record Book: Every genome is a historical archive, preserving the genetic footprints of life’s journey through time.
Shared Genes, Shared Origins: Humans share over 98% of their DNA with chimpanzees—clear proof of a common ancestor.
The Same Code Everywhere: From bacteria to birds, all life uses the same genetic alphabet, showing evolution’s single starting point.
Molecular Clues of Descent: Closely related species have more similar DNA, forming a genetic family tree that matches the fossil record.
Hidden Relics in Our Genes: Pseudogenes—broken, unused DNA sequences—are like fossilized pages left behind by evolution.
Evolution Caught in Real Time: Scientists have seen DNA evolve in bacteria, viruses, and finches as they adapt to new challenges.
The Tale of the Whale: Whales carry dormant genes for legs—molecular echoes of their land-dwelling ancestors.
Humans Carry Ancient Cargo: Fragments of viral DNA buried in our genome reveal infections our ancestors survived millions of years ago.
The Genetic Clock: Mutations accumulate at steady rates, letting scientists estimate when species diverged in Earth’s history.
Proof Written in Every Cell: The DNA inside you tells the same story as fossils, anatomy, and geography—evolution isn’t a theory in doubt, but a fact in motion.
