Smithsonian Tropical Research Institute The first humans to pluck a Caribbean fighting conch from the shallow lagoons of Panama's Bocas del Toro were in for a good meal. Smithsonian scientists found that 7,000 years ago, this common marine shellfish contained 66 percent more meat than its descendants do today. Because of persistent harvesting of the largest conchs, it became advantageous for the animal to mature at a smaller size, resulting in evolutionary change. Human-driven evolution...

Divers are combing the depths of ocean waters 60 miles south of the Mexican coast in search of the unique queen conch shell that may help scientists better understand the effects of global warming on the fragile aquatic ecosystem. Researchers were attaching electronic probes to more than 50 queen conch specimens that are native to these waters. The probes will gather informational data that will help in the study of climate changes off the Yucatan Peninsula. The information they gather may be...

BOCA RATON, Fla., Nov. 6 /PRNewswire-USNewswire/ -- For more than 25 years, all attempts at culturing pearls from the queen conch (Strombus gigas) have been unsuccessful--until now. For the first time, novel and proprietary seeding techniques to produce beaded (nucleated) and non-beaded cultured pearls from the queen conch have been developed by scientists from Florida Atlantic University's Harbor Branch Oceanographic Institute (HBOI). With less than two years of research and...

And here it is. Let's say you manage to get a job in a jewelry store and a customer comes in and asks to see a very expensive ring. And then he asks to see another expensive ring, and another and another. And then starts hanging diamond necklaces around his neck and pointing ring-studded fingers at...
