It was announced that the genomes for tigers, lions, and snow leopards were sequenced. This helps scientists learn a lot about these cats, such has how a snow leopard can survive in high altitudes.
It was also determined that tigers and house cats share 95.6% of their DNA in common. If anything, I’m a bit surprised by how small that figure is. However, as I’ve often noted, it’s the diversity among the cat species–how a single platform has evolved a variety of capabilities–that fascinates me.
