De Vries was a Dutch botanist whose theory of biological mutation and rediscovery of Mendel’s laws of heredity made possible the active investigation and universal acceptance of Darwin’s theory of evolution. He held that new species are formed chiefly through mutations—sudden, unpredictable, inheritable changes in an individual organism. Teaching at the University of Amsterdam, he introduced the experimental study of evolution. What important evolution-related term did he introduce to science? Discuss
