(via Chimps catch yawns from dominant males - life - 25 July 2012 - New Scientist)
A fascinating study. It shows that members (both male and female) of a chimp society pick up on the male members’ yawns much more than on the yawns of females in the group. Chimps are patriarchal to the extreme, so this, of course, makes sense. With male dominance for approximately 2 million years, it seems a self-imposed evolutionary twist has occurred within this species. I would guess yawning is just the tip of the iceberg. I think there are many implications inherent to this confirmation.It is always interesting to see studies come forth which emphasize specific points which may seem readily apparent to many.
