How people in the Paleolithic Age would have benefited from working in pairs vs. working in groups?

The availability of food and shelter would be greater if people in the Paleolithic Age worked in pairs.

Explanation:

During the Paleolithic age, human beings were nomadic and changed homes all the time. In addition, they worked in groups to find food and shelter.

Although group work was efficient, the availability of food and space became more limited as more individuals joined the group. If the humans of that time worked in pairs, the availability of food and shelter could benefit, since the division of these factors would be for a small number of people.
