An illustration of Darwin's noting that there is natural variation in plants (and animals). This variation is the raw material for evolution. Unfortunately, Darwin was born in the wrong century. We learned after the discovery of genetics and its agents, namely, genes, that plants can double or triple or even more-fold change its genes in one generation, thereby giving rise to new species in one generation. Endless ages of natural selection is not necessary for plants. (05/56)
