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.
With Auto-MDIX straight-through cable and Ethernet, crossover cable can be used. Switches and hubs not having Auto-MDIX will typically have one port that will not cross the line or crossover. MDIX is a version of the medium dependent interface (MDI), which is a module of the media attachment unit (MAU). The MAU is a transceiver converting signals on an Ethernet cable for which it transmits and receives attachment unit interface (AUI) signals. The standard for the MDIX is the MDI standard.
