Discover evolution of life on earth, plant evolution, sea animals evolution, bird evolution, silicon based life, multicellular life, world’s oldest fossils, animal biodiversity, bacterial life, bird like dinosaurs, rare ancient worms, animal speciation. Also get to know about Earth’s earliest life and how photosynthesis began producing oxygen billion years ago.

  • A new concept is challenging one of the basic assumptions of the theory of evolution - that survival is based on a change's functional advantage if it is to persist.

  • Sixty-five million years ago, a mass extinction on Earth wiped out the dinosaurs. New research now indicates that a separate extinction event occurred shortly before that, triggered by volcanic eruptions that warmed the planet.

  • A new study shows how tiny sea creatures called rhabdopleurids have survived for more than 500 million years and outlasted more elaborate species that descended from a common ancestor.
