On Sunday, it will be exactly 203 years since the birth of Charles Darwin.
And if that doesn’t seem particularly noteworthy to you, don’t say so to the Concord Area Humanists. The group is planning a gala celebration in honor of the evolutionary biologist, complete with a discussion, a Darwin impersonator, a birthday cake, and a showing of “Journey of the Universe,’’ a documentary by Brian Thomas Swimme and Mary Evelyn Tucker.
But there’s always room for more among their midst, which is why the group hopes for a strong turnout Sunday. And though it’s a long way from Darwin’s England (or the Galapagos Islands) to Concord, members believe that observing the scientist’s birthday is an important way of celebrating their cause.
According to Concord Area Humanists coordinator Patrick Everett, a retired engineer and longtime Darwin devotee, the party will begin with lunch at 1 p.m. at First Parish in Concord, 20 Lexington Road. A Darwin impersonator will circulate among the group for informal discussion of his ideas.
Following the cutting of the 19th-century naturalist’s birthday cake, the film will be screened at 2 p.m. Audience members can then share their reactions with a panel comprising Abby Hafer, who holds a doctorate in zoology from Oxford University and teaches at Curry College, and Ellery Schempp, a lifelong humanist and retired professor who taught physics, chemistry, and energy at the University of Pittsburgh and the University of Geneva in Switzerland; and “Darwin’’ himself.
Calling Darwin Day “a celebration of science and reason,’’ Everett said it was first observed in 1993, and is now recognized globally to acknowledge the biologist’s achievements, and how they have contributed to the advancement of humanity.
“Darwin’s masterwork, ‘On the Origin of Species,’ published in 1859, changed the thinking about how we came to be as we are,’’ Everett said.
The 60-minute “Journey of the Universe’’ film “tells the story of how we came to be, starting with the big bang through the transformation of the universe over 14 billion years . . . tracing first life through Darwinian evolution leading to millions of species, including us,’’ said Everett. “The movie ends with the question: ‘What now?’ And our panel of experts will pick up the discussion from there.’’
To attend Sunday’s event, RSVP to email@example.com (put “Darwin’’ in the subject line). Suggested donations are $5 per person, $10 per family, payable at the door. For details on the host group, go to www.meetup.com/concordareahumanists.
