General Admission
What genetic evidence buried beneath the ocean floor reveals about how species respond to climate change.
Antarctica is highly vulnerable to climate change, and scientists are racing to understand how Antarctic ecosystems will be affected. One way to predict these effects is to investigate how past marine life responded to environmental change by extracting sedimentary ancient DNA from the seafloor around Antarctica. This DNA provides a record of past Antarctic life, revealing who lived when and where. By analysing this ancient DNA from thousands, and even millions of years ago, we can reconstruct shifts in biodiversity, track the appearance or disappearance of species, and examine how ecosystems changed during periods of warming, cooling, or altered ocean circulation.
