An evolutionary biologist paid homage to his Canadian roots as he and his wife were presented with the Kyoto Prize on Tuesday at a ceremony in Japan.
Peter and Rosemary Grant received the prize in basic sciences for their work looking at rapid evolution caused by natural selection in response to environmental change.
They are both professors emeriti at Princeton University and the first husband-and-wife team to receive the Kyoto Prize, which is Japan's highest private award for global achievement honouring contributions to the "scientific, cultural and spiritual betterment of humankind."
Peter Grant has dual citizenship from Canada and the United Kingdom, and received his PhD from the University of British Columbia in 1964. He was a professor at McGill University in Montreal from 1965 to 1977.
Rosemary Grant spent time as a research associate at UBC and McGill in the '60s and '70s, and received her PhD from Uppsala University in Sweden.
"I was born less than 10 miles from where (Charles) Darwin wrote his major work, 'On the Origin of Species,"' Peter Grant said in his acceptance speech.
"However, our research was launched not from Britain but from Canada, and has continued for many years through the U.S.A., our home for the last 30 years. With this tri-national background, it is impossible not to be international in outlook."
The couple has spent more than 35 years doing field studies in the Galapagos Islands, and looked at how beak size and shape evolve through natural selection within a dramatically changing environment, according to certain mechanisms and conditions.
A book about their work, "The Beak of the Finch," won a Pulitzer Prize.
On Tuesday, they received a diploma, a 20-karat-gold Kyoto Prize medal, and a cash gift totalling 50 million yen (approximately US$550,000) from the non-profit Inamori Foundation.
Other Kyoto Prize recipients this year are:
Isamu Akasaki, a semiconductor scientist and a professor at Nagoya University and at Meijo University in Japan.
Maestro Pierre Boulez, an internationally renowned composer, conductor and honorary director of the Institute for Research and Co-ordination Acoustic/Music (IRCAM) in France.
