(It remains by far the oldest DNA yet sequenced.) Among the researchers’ many findings from this scientific trove: Horses, donkeys and zebras appear to have evolved from a common ancestor 4 million to 4.5 million years ago, or twice as long ago as previously thought.

A variety of “experts” ridiculed Darwin’s prediction, published in 1862, that such a moth must exist somewhere on Madagascar.

(Ridicule was an experience he must have been used to by then.) It wasn’t until 1903 that collectors found the exact moth that he’d said was out there: Xanthopan morganii, originally given the subspecies name praedicta in recognition of the great man who predicted its existence.

Meanwhile, a thin layer of guanine crystals (called the retinal tapetum) lies just behind the eyes.

By reflecting light back through the retina, it intensifies the image, aiding crocodiles as they hunt in low-light situations.

And more than 80 years after that, it was further confirmed: The Xanthopan morganii was documented feeding on this exact flower.

This moth is one of the fascinating examples of the extraordinary ways in which plants and animals have adapted elegant solutions for survival, collected in photographer Robert Clark’s new work, “Evolution” (Phaidon) with text by Joseph Wallace.
