In 2011, Bonde agreed with Ferguson that Lucy should be split into a new species, though erected a new genus as "Afaranthropus antiquus".

In 1948, German palaeontologist Edwin Hennig proposed classifying these remains into a new genus, "Praeanthropus", but he failed to give a species name. A perceived difference in male and female size may simply be sampling bias. S1 appears to have had the highest average step and stride length of respectively 505–660 mm (20–26 in) and 1,044–1,284 mm (3.4–4.2 ft) whereas G1–G3 averaged respectively 416, 453, and 433 mm (1.4, 1.5, 1.4 ft) for step and 829, 880, and 876 mm (2.7, 2.9, 2.9 ft) for stride.
