Outline how the honeyguide-human mutualism could have evolved from an earlier mu

Humans observing the relationship between the honeyguide and honey badger could have begun to imitate the badger. Honeyguides that guided these solicitous humans may have had more ready access to bees' nests because of the greater resourcefulness of their new human mutualists, and thus selection for guiding humans would have occurred. In much of modern Africa, honeyguides which persist in trying to guide humans waste time and energy that could be applied to other functions, such as reproduction. Natural selection should eventually eliminate the individual honeyguides that persist in this behaviour, via their reduced fitness.
