190-year-old DNA Reveals a Hidden Pangolin Species

Topic: Biology

Scientists have confirmed that a previously unknown pangolin species exists in Nepal and Northern India. They used DNA evidence from a 190-year-old specimen to prove it. This discovery will help protect endangered pangolins.

Pangolins are medium-sized mammals with long, powerful tails and large curved claws. They have bodies covered in overlapping scales that look like a pinecone. These distinctive scales make them a target for poachers, who heavily traffic them.

In Nepal and Northern India, researchers found evidence of a previously unrecognized pangolin species called Manis aurita. This discovery was made possible by analyzing DNA from a 190-year-old specimen stored at the Natural History Museum in London. The team used this ancient DNA to compare it with modern Himalayan pangolin samples.

The study, published in Communications Biology, clarifies how different pangolin species are related and where they live. This information will help authorities identify where illegally traded pangolins come from and strengthen efforts to stop poaching.

Why It Matters

This discovery is important for India because it highlights the need to protect endangered animals like pangolins, which are heavily trafficked in our country.
