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.
For example, in a 100BaseTX network, the second and third pair must be swapped at each end to create a crossover cable. A crossover cable is also used to create mesh networks that work without an intermediate network device, such as a hub or switch.
