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.
[A] Crossover Cables are used to connect networking components together. As a rule, these devices will be alike. An example of like devices would be connecting your computer to another computer to share files and other resources. This is known as a peer-to-peer network. Crossover Cables are used to connect fewer types ofl networking components together and are the least common as a result. Crossover cables are wired using the EIA/TIA standard 568-B on one end, and the EIA/TIA standard 568-A on the other.
