Let's make this birthday one to remember.

83 years old (Born on September 10, 1941)

Happy Birthday to the legendary Stephen Jay Gould! Your brilliant insights into evolution and paleontology have made dinosaurs cool again, turned fossils into rock stars, and reminded us all that science can be both profound and delightfully entertaining. From "Ever Since Darwin" to "Dinosaur in a Haystack," you've shown us how fascinating—and funny—life's history truly is.

Being named a "Living Legend" by the U.S. Library of Congress was just icing on your evolutionary cake (or perhaps fossilized frosting?). Here's hoping your birthday celebration evolves spectacularly—filled with laughter, joy, and absolutely no mismeasuring of cake slices!
