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.
Ethernet crossover cable is used to connect a computer network made up of two or more computers. This type of network cable eliminates the need for network switches or routers. The cable also allows the computers to be connected using their network adaptors, such as the network interface card (NIC). Fiber optic network cables are used for networks that span large distances. As a result, this type of cabling has several layers of protective coating.
