• Resumen

  • This article examines genomic findings in the DNA of the world's wild cats and says the information has clarified the cat family tree and uncovered remarkable migrations in their past. DNA evidence shows that all living cats trace back to a pantherlike predator that lived in Southeast Asia nearly 11 million years ago. The big roaring cats were the first to branch off and seven other lineages followed. As the sea levels rose and fell, the cats migrated and developed into new species.
