Polar Bears Adapt via Jumping Genes

Polar bears in southeast Greenland are adapting to warmer climates by changing their DNA.

These bears have special pieces of genes called 'jumping genes' that can move around and help them adapt to new environments.

The southern bears have genes that work differently for handling heat, aging, and metabolism compared to northern bears.

This adaptation might help them survive as their habitat changes due to climate change.

However, scientists say that even with these changes, polar bears are still at risk of extinction and need our help to reduce carbon emissions.

Humans also have similar jumping genes, and our DNA can change too, but environmental stress can speed up this process.
