Johanson hypothesized nearly instantly one Lucy was a lady due to her small size. He had been knowledgeable about fossil hominin breakthroughs produced by almost every other boffins, various other elements of Africa, when you look at the years prior to the Lucy finding. The guy know one, like other life style primates, hominins tended to getting sexually dimorphic, meaning the fresh new men were larger than the newest people; thus, they checked obvious that the relatively quick skeleton retrieved from An effective.L. 288 had been that from a woman (select Scott & Stroik, 2006, to own a dialogue of one’s alternative varieties of sexual dimorphism for the Lucy’s varieties).

After, scientists estimated Lucy’s peak according to the duration of their particular femur, whilst stop away from their femur was actually soil earlier accomplish fossilization. It used analytical formulas one connect femur duration so you can stature to predict you to definitely Lucy endured up to 104 so you’re able to 106 centimeters (cm) extreme (Feldesman & Lundy, 1988; Jungers, 1988; McHenry, 1991). Men of Lucy’s varieties was in fact most likely closer to 150 cm tall (McHenry, 1991). For the 2008, a small grouping of boffins practically rebuilt Lucy’s busted femur using three dimensional computer-situated technology and discovered it was probably just a few millimeters less than was previously consider (Sylvester, Merkl, ainsi que al. ukrainian charm, 2008).
