Biodiversity Benefits Society in Surprising Ways

Extremophile kick-starts new industries
After the discovery of a bacterium that lives at extremely high temperatures in Yellowstone National Park’s hot springs, scientists extracted a heat-resistant enzyme that helps copy DNA. This enzyme was used to develop a lab technique for rapidly duplicating DNA with the help of repeated heating and cooling cycles. Known as the polymerase chain reaction (PCR), this technique enables DNA fingerprinting, an essential forensics tool, and much of the biotechnology industry, worth more than $95 billion today.

Every organism on Earth, from microbes to plants to large predators, has evolved unique survival mechanisms and distinct ecological roles. For decades, the National Science Foundation (NSF) has funded basic research on how these varied organisms — the Earth's biodiversity — functions.
