The hominin character matrix of Dembo et al. (2016) has been updated with additional character states for Ar. ramidus, Au. anamensis, H. antecessor, and H. floresiensis.  These characters were published and described in Wood (2020).

From Mongle et al. (2019), I added 48 character states from Table 4 for Ardipithecus ramidus, with the following exceptions:

• Characters missing from Dembo: SG53, CW2, CW22, CW40, CW48, KRJ6, KRJ25
• Characters already coded: KRJ11, SG25
• In addition, the description of SG42 matches that of Dembo235, but the character state does not match at all.  SG42 was omitted from this modified dataset.

From Haile-Selassie et al. (2019), I added 50 character states for Australopithecus anamensis.  I scored character 87, zygomaticoalveolar crest, as “curved” for Homo antecessor, based on Trafi et al. (2018).  In addition, I added 84 character states for Homo floresiensis based on Argue et al (2017) (29 characters) and my own study of published anatomical descriptions and photographs of fossils (55 characters).   All modified character states for H. floresiensis are documented below.

Finally, the character states are supplied in two forms.  The polarized set follows the original character state codings from Dembo et al. (2016), and for the unpolarized set, all characters were recoded so that character state zero referred exclusively to the absence of a character state.
