Manual morphology regarding H. rudolfensis is unfamiliar, hence out of H. erectus is actually unknown. erectus s. l., as well as out-of Homo neanderthalensis and you will H. sapiens by lacking a styloid procedure (Ward et al., 2013).
H1 is then well known out-of H. neanderthalensis and you can H. sapiens by its relatively quick factors to the Mc1 and you can scaphoid to your trapezium, its low angle between your Mc2 and you can Mc3 aspects to the capitate, and by their enough time and you will rounded proximal and you may advanced phalanges into rays dos–5.
H1 try classified from all the known hominins in the that have a beneficial Mc1 that mixes an excellent mediolaterally slim proximal prevent and you may articular factors that have a good mediolaterally broad distal shaft and lead, an excellent dorsopalmarly flat and you can firmly asymmetric (that have an expanded palmar-lateral protuberance) https://hookupdate.net/cougared-review/ Mc1 lead, together with mixture of a total later on Homo-like carpal morphology and proximal and you may intermediate phalanges that will be more rounded than just very australopiths. H1 along with differs from any kind of recognized hominins except H. neanderthalensis into the which have non-pollical distal phalanges having mediolaterally wider apical tufts (in line with size).
Femur (U.W. 101-1391)
Brand new femur out of H. naledi differs from that from any other identified hominins within its possession out of a couple well-defined, mediolaterally-powering pillars regarding the femoral shoulder. This new pillars work on along the superoanterior and you may inferoposterior margins of your own shoulder and you can describe a distinct sulcus along the advanced aspect.
Tibia (You.W. 101-484)
The new tibia out of H. naledi is different from the ones from every other recognized hominins in possession from a distinct tubercle to your pes anserinus ligament. The fresh tibia is different from other hominins but H. habilis, H. floresiensis, and you can (variably) H. sapiens within its fingers from a rounded prior edging.
Ft (F1)
The newest feet out-of H. naledi is different from the fresh pedal remains out of Au. afarensis, Bien au. africanus, and you can Au. sediba when you look at the that have a beneficial calcaneus that have a great weakly developed peroneal trochlea. F1 including differs from Bien au. afarensis during the which have a top positioning of one’s calcaneal sustentaculum tali. F1 can be further notable of pedal remains associated with Au. africanus into the having a high talar head and you will shoulder torsion, a narrower Mt1 ft, a good dorsally prolonged Mt1 lead, and you can greater proximolateral to help you distomedial direction of your horizontal metatarsals. The brand new H. naledi base will likely be after that differentiated throughout the legs away from Au. sediba into the having a beneficial proximodistally compliment talar trochlea, an apartment subtalar shared, an excellent diagonally oriented retrotrochlear eminence and you can a great plantar standing of your own horizontal plantar procedure for the newest calcaneous, and you may dorsoplantarly apartment articular skin to the cuboid with the Mt4 (Zipfel ainsi que al., 2011). Pedal remains from Bien au. garhi are presently unfamiliar, and those regarding P. robustus are way too badly known to accommodate analysis.
The fresh new H. naledi base are distinguished regarding the foot out-of H. habilis by presence away from a flatter, non-sloping trochlea having similarly elevated medial and lateral margins, a narrower Mt1 foot, deeper proximolateral in order to distomedial orientation of horizontal metatarsals, and a good metatarsal robusticity ratio of 1 > 5 > 4 > step 3 > 2. Pedal morphology within the H. rudolfensis is unknown, which regarding H. erectus is simply too poorly recognized to allow for analysis. New H. naledi ft shall be renowned regarding foot out-of H. floresiensis of the a lengthier hallux and you will less 2nd as a consequence of 5th metacarpals in accordance with hindfoot duration, and higher torsion of the talar lead and you will neck.
The brand new feet off H. naledi should be prominent regarding the feet away from H. sapiens merely by the its flatter horizontal and medial malleolar issue towards this new talus, their lower position away from plantar declination of talar direct, the straight down orientation of one’s calcaneal sustentaculum tali, and its particular gracile calcaneal tuber.
