A new genomic study has found that whales have experienced natural selection as a result of past climate changes. Researchers in Spain and South Africa analyzed the genetic profiles of whales, porpoises, and dolphins of two species (minke whales and southern right whales), to explore how their genes have changed over time.

The study revealed that these marine mammals have evolved to cope with various challenges, including shifting food supplies and changes in sea ice coverage and water temperature.

As ocean conditions continue to change rapidly due to human-induced climate change, this research adds further insight into the ways whales might adapt to the dynamic marine environment. However, additional studies are needed to assess the impacts of the unprecedented rapid and intense human-caused environmental changes occurring nowadays.

It can provide valuable insights into conservation efforts. By understanding how the whales have adapted historically, scientists can gain insight into potential future adaptations, vulnerability risks, and strategies to conserve the marine population amidst ever-changing climate conditions.
