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.

The main point of ribbon cables is to allow mass termination to specially designed IDC connectors in which the ribbon cable is forced onto a row of sharp forked contacts. (The phrase IDC connector is widely used, even though it is redundantâan example of RAS syndrome.)
