The Molecular Clock That Tracks Evolution’s Timeline

Time Written in DNA: Every species’ DNA changes at a steady rate, letting scientists read time directly from the genetic code.
The Molecular Clock Explained: By counting mutations, researchers can estimate when two species last shared a common ancestor.
Mutation as a Ticking Clock: Each tiny DNA change acts like a tick on evolution’s timeline—steady, measurable, and universal.
Fossils Meet Genetics: Fossil dates anchor the molecular clock, linking ancient bones to modern genomes.
Calibrating Life’s History: Different genes tick at different speeds—fast ones trace recent splits, slow ones reveal deep time.
From Cells to Civilizations: This genetic timekeeper helps map everything—from when humans left Africa to when whales left land.
A Universal Timepiece: The molecular clock works across species, offering one timeline for all of life on Earth.
Revealing Hidden Connections: DNA timelines uncover relationships invisible to fossils—like the genetic ties among birds and dinosaurs.
Not Perfect, But Powerful: While mutation rates vary, the molecular clock remains one of evolution’s best tools for dating life’s story.
Reading Time in Every Cell: Your DNA carries a record of millions of years of evolution—each gene a silent witness to life’s unfolding past.
