PATILLAS, Puerto Rico — A curtain of sound envelops the two researchers as they make their way along the side of a mountain in darkness, occasionally hacking their way with a machete to reach the mouth of a small cave.

Peeps, tweets and staccato whistles fill the air, a pulsing undercurrent in the tropical night. To the untrained ear, it’s just a mishmash of noise. To experts tracking a decline in amphibians with growing alarm, it’s like a symphony in which some of the players haven’t been showing up.

Species have become extinct & new ones come into being since evolution started. I don't understand the desire to freeze evolution in time.

I'm not sure there is one. Just a desire for greater understanding of evolution and the human impact on what is essentially very natural.After all we did influence evolution quite extensively with acid pollution.
