|Planckendael Bonobo Study 2000|
Clips of bipedal wading...
Here are a few examples of the kind of bipedal wading that was observed in the short study at Planckendael. Notice how the apes naturally knuckle walk towards the water and switch to bipedalism only for moving the short distance in even relatively shallow water to collect food items. Once the food has been collected, notice how they switch back to quadrupedalism again. This behaviour was observed in several individuals, most notably the alpha female which did so whilst carrying her infant.
