Octopus DNA and the West Antarctic Ice Sheet

Interesting!:

A study of octopus DNA may have solved an enduring mystery about when the rapidly melting West Antarctic ice sheet last collapsed, unlocking valuable information about how much future sea levels may rise in a warming climate.

The innovative research focused on the genetic history of the Turquet’s octopus (Pareledone turqueti), which lives on the seafloor across the Antarctic, and what it could reveal about the geology of the region over time. 

Tracing past encounters across the species’ various populations suggested the most recent collapse of the ice sheet occurred more than 100,000 years ago during a period known as the Last Interglacial — something geoscientists suspected but had not been able to confirm definitively, according to the study published Thursday in the journal Science.
