, who all roar, or Felinae, the ‘little cats’ including lynxes, cougars, ocelots and pet cats.
‘Evolutionarily speaking, sabertooths split off the cat family tree before these other modern groups did,’ said co-author Adam Hartstone-Rose, professor of biological sciences atState University. ‘This means that lions are more closely related to house cats than either are to sabertooths. ‘That’s important because the debate over the kind of vocalisation a sabertooth tiger would have made relies upon analysing the anatomy of a handful of tiny bones located in the throat.’In modern cat species, whether they purr or roar is thought to be related to the number of hyoid bones in the throat. While vocalisation is driven by the larynx and soft tissue in the throat, cats that roar have been found to have seven hyoid bones linked together, and purring cats have nine.
