Summary:
Being able to mentally consider quantities makes sense for any social species. This skill is important during the search for food, for example, or to determine whether an opponent group outnumbers one’s own. Scientists have studied how well dogs can discriminate between different quantities and discovered that wolves perform better than dogs at such tasks. Possibly dogs lost this skill, or a predisposition for it, during domestication, the researchers suggest.
