Earlier in April I spent an afternoon at Harvard’s Natural History Museum. The Glass Flowers are the museum’s most famous exhibit, but I was drawn to the taxonomy rooms where entire jungle populations inhabit a few glass cases. My favorite fun fact from the visit: frogs do not have green skin. They have yellow skin with grooves that reflect blue light. Our human eyes detect their yellow pigment mixed with this blue light, and abracadabra: we see green.
