Life's origins are shrouded in mystery, with hypotheses pointing towards pre-biotic molecules and the emergence of RNA as a critical factor.
Prokaryotes (3.5-2 Billion Years Ago)
The first cell organisms, known as prokaryotes, made their debut around 3.5 billion years ago. These early life forms lacked membrane-bound organelles.
Eukaryotes (2 Billion Years Ago)
A significant evolutionary leap occurred with the emergence of eukaryotic cells. They contained membrane-bound organelles, including a nucleus housing DNA, the blueprint of life.
Multicellularity and Diversification (1-0.5 Billion Years Ago)
Multicellular life made its appearance, resulting in a proliferation and diversification of organisms, setting the stage for complex ecosystems.
Cambrian Explosion (541 Million Years Ago)
A remarkable period of rapid diversification known as the Cambrian explosion saw a burst of complex life forms. This event marks a crucial juncture in Earth's history.
Vertebrates and Dinosaurs (500-65 Million Years Ago)
Vertebrates, including the mighty dinosaurs, emerged and conquered the land and oceans. The age of dinosaurs stretched for over 160 million years until their extinction.
Mammals and Human Evolution (65-Present)
With the demise of dinosaurs, mammals rose to dominance. Among them, the human lineage embarked on a remarkable evolutionary journey that would eventually give rise to Homo sapiens, the modern humans.
Human Civilization and Technological Advancements (Last 12,000 Years)
Humans established civilizations, fostered agriculture, and made technological advancements that shaped our societies and altered our relationship with the environment.
