Research overview: ancient DNA methods applied to extinct and historical felids

Recovering DNA from extinct cats and historical museum specimens requires specialized techniques to cope with degraded, fragmented, and contaminated genetic material. This overview surveys how researchers extract and authenticate ancient felid DNA, the advantages of permafrost preservation for Ice Age species like cave lions and Homotherium, and the use of target-capture and shotgun sequencing to reconstruct mitochondrial and nuclear genomes. It discusses how these methods have resolved questions about cave lions, sabertooths, the Barbary lion, and the history of domestic cat dispersal, and how authentication safeguards distinguish genuine ancient sequences from modern contamination in the study of felid evolution.
