The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day.
Life - Evolution, History, Earth: The evidence is overwhelming that all life on Earth has evolved from common ancestors in an unbroken chain since its origin. Darwin’s principle of evolution is summarized by the following facts.
A Timeline of the Eons’s, Era’s, & Periods. The development of life over the last 3,700 million years of the Earth's history is one of the great stories told by modern science. During most of this time living things left only traces to indicate their existence.
New discoveries are always adding key waypoints to the chart of our human journey. This timeline of Homo sapiens features some of the best evidence documenting how we evolved.
These include major geologic events, climate changes, radiation of organisms into new habitats, changes in ecosystems, changes in continental positions, and major extinctions. Explore the timeline below to view some of the major events in life’s history.
Resolving the theoretical challenges of evolution’s timetable will sharpen our understanding of life’s long evolutionary history while informing continuing astrobiological exploration of our own solar system and beyond.
