I agree that a group increases survival for all reasons given.
During my survival course, tasks soon became divided up, one collecting wood, another water and processing it, another tending to shelter another building signal fire and so on
Its the basis of team work and division of labour. Or "many hands make light work"
But more people require more food... But if water, shelter, fire etc is being sorted by others, a member is freed up for constant hunting, gathering, snare tending etc
