Abstract
Methods
Data are 3D landmarks and semilandmarks from the frontal bone (all_coord_f2.csv) and occipital bone (all_coord_o2.csv) of Homo erectus (extinct hominin) fossils and comparative Homo sapiens (recent humans). Data were collected with a 3D Microscribe digitizer. Missing landmarks were estimated using several procedures (described in SI of original article).
Also included are files required to 'slide' the semilandmarks (sliders_Frt.csv and sliders_occ.csv)
The final file is R code for performing anlyses presented in article.
Usage notes
The following human population abbreviations were used: Aust = Aboriginal Australians; Lach = Lachish, Israel; Anda = Andamanese Islanders; Teit = Teita, Kenya; Ngui = New Guinea; Chin = Chinese; Grgl = Grand Gulch, Utah (Anasazi); Ipiu = Ipiutak from Point Hope, Alaska.
Columns in landmark files: indiv = fossil abbreviation; spp = species; pop = population; pop_simp = not used in current study; V1-V3 = x, y, and z coordinates of landmark 1, and so on
