The shoes floated low in the water, while the ducks floated high in the water. how could this fact have changed the course and speed of both the shoes and the ducks?

when the shoes floated low in the water, while the ducks floated high in the water. The speed of the duck in water is much faster than the shoes because the duck will overcome less resistance like water current because it has lesser contact area. The shoes has greater probability to change course because of larger contact area

 

  like australopithecus afarensis; probably the direct ancestor of this group. africa: 5.8 to 4.4 million years ago.
