DARIEN — Though he is not a scientist, John Levin loves science.

“It’s so interesting. The mysteries of the universe are unveiled to us through science. They’re so strange and so odd and full of very compelling and fascinating stories that just never seem to end,” Levin said.

Nine years ago, the Norwalk resident’s passion for science, combined with the 200th birthday of Charles Darwin, arguably history’s most famous scientist, on Feb. 12, compelled him to begin the annual Darwin Day Dinner.

“To quote others, ‘Darwin is the man!’ ” Levin said. “Evolution through variation and natural selection is the bedrock of our understanding of life on Earth and anywhere else in the universe. Darwin is the one who gets credit for being the first to articulate that process.”

Each year, Levin invites distinguished scientists to present and speak about their work.

This year, Walter Jetz, associate professor in the Department of Ecology and Evolutionary Biology at Yale University and director of the new Yale Center for Biodiversity and Global Change, will display his work, “Chasing Birds with Satellites — Taking the Pulse of the Planet,” onSaturday at 6 p.m. at the Water’s Edge at Giovanni’s for the ninth annual Darwin Day Dinner. The evening will include a cocktail hour, dinner, a science quiz and prizes.

Since the inaugural Darwin Day celebration, the party has continued to grow. This year, Levin expects around 200 people coming from as far as Boston and New York City in the name of science.

“Full disclosure, it’s a little bit of a nerd-fest,” Levin said.
