Hivegenic

undefined:

Hivegenic refers the process whereby a headmate originates from within a cluster or "hive" of existing headmates. When the hive encounters a situation which calls for a specialization or an emotional response outside the scopes of the existing headmates in the hive, a new headmate can form within the hive to handle it. This new headmate may share traits with the other members of the hive.
