Origin of Life


Scientists found microscopic fossils of blue algae which were traced back from Pre- Cambrian era i.e.,3000 million years old. Thus, it is believed that the origin of life on the planet earth started with unicellular bacteria sometime 3800 million years ago. Since then, it starts evolving into a modern-day man. The evolution from unicellular bacteria to modern-day man is depicted in the above flow chart.
