A. afarensis probably was quite an efficient bipedal walker over short distances, and the spacing of the footprints at Laetoli indicates they were walking at 1.0 m/s or above, which matches human small-town walking speeds.onsiderable debate surrounds the locomotor behaviour of A. afarensis. Some studies suggest that A. afarensis was almost exclusively bipedal, while others propose that the creatures were partly arboreal. The anatomy of the hands, feet, and shoulder joints in many ways favour the latter interpretation.
Crossover cables are typically used in the following situations: Use a crossover cable when: 1  1. Connecting a computer to a router. 2  2. 3  Connecting a computer to a computer. 4  3. Connecting a router to a router. 5  4. Connecting a switch to a switch. 6  5. 7  Connecting a hub to a hub.
Also, unless the ports on the switches are crossover-X auto sensing, the Cat5 cable will need to be a crossover cable. Not a straight through as most pre-packaged Cat5 cables are. This is because your between to like (layer 2) devices.
