Let's make this birthday one to remember.

87 years old (Born on March 05, 1938)

Happy Birthday to the legendary Lynn Margulis! Your groundbreaking discovery of how eukaryotic organelles originated through symbiosis forever changed biology. Thanks for showing us that animals, plants, and fungi all trace their roots back to humble protists—talk about family reunions getting complicated!

And let's not forget your cosmic connection with Carl Sagan; clearly, you both had a knack for exploring life's biggest mysteries. Today we celebrate your brilliance, humor, and fearless curiosity. May your legacy continue inspiring scientists everywhere—and may every birthday remind us that even microscopic organisms can have superstar status in biology textbooks!
