Microbes' Crucial Role Recognized
- Microbes have been Earth's primary inhabitants for nearly four billion years and were vital in shaping complex life conditions.
- Despite some being harmful to humans, their true significance lies in environmental and ecosystem regulation.
Origin of Life at Ocean Vents
- Life likely began at ocean vents where hydrogen gas reacted with acidic CO2, producing life's building blocks.
- Primitive bacteria from these vents still exist and are now key players in combating global warming.
Bacterial Fusion Enabled Complex Life
- The modern cell emerged when two bacteria fused, with one becoming the mitochondrion powering energy production.
- This fusion enabled the evolution of multicellular organisms by allowing oxygen usage for higher energy needs.
