Rats may have ‘best bite of rodent world’
Mice and rats have evolved to gnaw with their front teeth and chew with their back teeth more effectively than rodents that ‘specialise’ in one or other of these biting mechanisms, according to a new study.
Scientists at the University of Liverpool designed a computer model to simulate the bite of rats to understand whether their skull shape or muscle arrangement was a major factor in their evolutionary success and global dominance, making them one of the most common pest species in the world.
