Quote by Carl Woese

"The RNA world is a hypothesis that suggests an early stage of life on Earth where RNA molecules performed the dual functions of storing genetic information and catalyzing chemical reactions."

"Microorganisms are the most successful form of life on Earth, having been here the longest and in the greatest numbers."

"The universal ancestor is the root of the tree of life, connecting all living organisms through common descent."

"Bacteria are not primitive ancestors of eukaryotes; rather, they represent a successful evolutionary strategy distinct from our own."

"Life is meant to be lived with passion."

"Life is what happens when you're busy making other plans."

"Life is a journey, not a destination."

"Life's too short for regrets."
