Canadian scientists say they have conducted the first experiment that shows the evolution of new species impacts the environment. Scientists at the University of British Columbia created mini-ecosystems in large aquatic tanks using different species of three-spine stickleback fish and saw substantial differences in the ecosystems within 11 weeks. Stickleback fish originated in the ocean, but began populating freshwater lakes and streams following the last ice age.
Scientists have come to agree that different environments impact the evolution of new species. Now experiments conducted at the University of British Columbia are showing for the first time that the reverse is also true.
