Big Brains and Dexterous Hands

Primates with large brains can master more complex hand movements than those with smaller brains. However, fine motor skills such as using tools can take time to learn, and humans take the longest of all. Large-brained species such as humans and great apes do not actually learn more slowly than other primates but instead start later, researchers at the University of Zurich have shown.
