Note: I received a digital review copy of this book from the publisher through NetGalley. This is the story of a prediction Charles Darwin made and how approximately 130 years later it was proven by another scientists. After receiving a star orchid from Madagascar, Darwin hypothesized how the flower was pollinated. Unfortunately he didn’t live long enough to find out if his hypothesis was true. Other scientist carried on his work and found a moth like Darwin had predicted to be about the right size and with a long probiscus to pollinate this flower. Unfortunately it took another scientist to set up night vision camera’s to actually prove Darwin’s hypothesis correct. The book gives information on each of the scientists and pictures of the actual moth pollinating the orchid. Great tool for the science classroom. sin reseñas | añadir una reseña

How long does it take for science to find an answer to a problem? On January 25, 1862, naturalist Charles Darwin received a box of orchids. One flower, the Madagascar star orchid, fascinated him. It had an 11.5 inch nectary, the place where flowers make nectar, the sweet liquid that insects and birds eat. How, he wondered, did insects pollinate the orchid? After experiments, he made a prediction. There must be a giant moth with a 11.5 inch proboscis, a straw-like tongue. Darwin died without ever seeing the moth, which was catalogued by entomologists in in 1903. But still no one had actually observed the moth pollinating the orchid. In 1992, German entomologist Lutz Thilo Wasserthal, Ph.D. traveled to Madagascar. By then, the moths were rare. He managed to capture two moths and released them in a cage with the orchid. He captured the first photo of the hawk moth pollinating the flower, as Darwin had predicted 130 years before. This pollen science book includes backmatter information on the moth, the orchid, Charles Darwin, and Lutz Wasserthal. Also included is Wasserthal's original photo taken in 1992.
