Once the breakdown of food starts in the mouth, our oesophagus is narrow and . The extent of recombination among the six FIV, subtypes within free-ranging lions is not yet known, but studies of Serengeti lions (where up to 93% of adult lions are infected) have shown that 43% of individuals are multiply infected with FIV, subtypes A, B and C allowing opportunities for recombination and possible evolution of more virulent strains. As such, maybe there is a higher environmental cost to holding a mane in this hot, arid area? In most cases, lions cannot eat plants because their digestive system cannot process plant matter.
