Big, old B.C. trees produce mutations over time that could improve success: study

Research may provide insights into what part the mutations could play in how trees often adapt to local climatesResearchers collected DNA from the tops of some of Canada's tallest trees to search for mutations that could provide evidence of how the ancient forest giants evolve to survive. It involved ascending 20 Sitka spruce trees on Vancouver Island, averaging 80 metres tall and ranging in age from 220 years to 500 years old, to reveal that the old-growth trees developed mutations to their gen
