Doyen of Evolutionary Biology-Edward O. Wilson
“Great biological diversity takes long stretches of geological time and the accumulation of large reservoirs of unique genes. The richest ecosystems build slowly, over millions of years. It is further true that by chance alone only a few new species are poised to move into novel adaptive zones, to create something spectacular and stretch the limits of diversity. A panda or a sequoia represents a magnitude of evolution that comes along only rarely. It takes a stroke of luck and a long period of probing, experimentation and failure. Such a creation is part of deep history, and the planet does not have the means nor we the time to see it repeated” (Wilson, 2001).
