Darwin And His Moth forecast

He did not talk about evolution and metamorphosis just like that. Charles Darwin, the 19th century naturalist, had gone to the extent of forecasting the existence of `types’ of species in the future too. As per his hypothesis a moth with a long tongue measuring between 12 and 14 inches must exist in order to pollinate a particular type of orchid. This was because the orchid’s nectar producing organs lay 12 inches inside the flower. Charles Darwin was proved right when Xanthopan morganii a hawk moth matching the specification given by him was discovered years later.
