Who is the leader of the pack?

In this case, two boys and three girls arranged almost linearly let us recall some features of the group hierarchy: 

- They are distributed in concentric designs. The center of the group as a privileged position to the alpha males and females rated the best is assumed; Partly for protection and also to be defined as the midpoint of the other members (and escuharlos to view them all without much effort). This distribution occurs naturally. 

- Who controls the herd maintains a security posture risky way of showing off; we could say that for humans the chin up is a symbol of dominance and superiority. In fact is associated with masculinity. 

If we take a look at the group, we note that the "core" of it is composed of three girls. Detailing them from left to right, the first (with cap) was shy and somewhat withdrawn note. As much as paint film archetypes to "alpha" of a joint venture as cold people hardly go unnoticed or are silent (which is what this girl intends to do). We would be the last two, arm in arm. Which one is the Alpha of the group? If we look to the right (number 4 of the team) has the decided step of all, chin up, open smile, holding her companion with arm and does not need a visual anchor in the eyes of other; She is a natural leader, the pacesetter.
