Beyond the reach of sunlight, thousands of feet below the surface of the ocean, some creatures create their own light known as "bioluminescence." Take a trip through the mind of Leo Smith, who asks questions about deep sea fish evolution. Patterns in diversity can offer clues to why fish have evolved so many ways of brightening up the deep sea. Some seem to use light to blend into their surroundings, others to lure prey out of the surroundings, or even to attract mates. Read more about Video: Leo on Bioluminescence
Species names are important, and much like the species they refer to, names often change over time, too. Taxonomists have been struggling to keep track of them all since the origins of natural history. Binomial nomenclature, the standardized way in which scientists name species, was a major breakthrough. Read more about Video: What's in a Name?
"The city is just a pseudo-cliff," says Mary Hennen, explaining a Peregrine falcon's perspective on Chicago's landscape.

Mary Hennen is the Collections Assistant in the Field Museum's Bird Division in addition to being the CPP's Director. She attributes much of the program's success to hard-working researchers and volunteers. Read more about Video: Recovering Peregrines with Mary
