However, H1 is different from a 3rd metacarpal caused by H
Tips guide morphology regarding H. rudolfensis is now unfamiliar, and this off H. erectus is actually unknown. erectus s. l., and additionally out-of Homo neanderthalensis and you may H. sapiens by the without a beneficial styloid techniques (Ward ainsi que al., 2013).
H1 is then distinguished out of H. neanderthalensis and you will H. sapiens from the the relatively quick aspects into the Mc1 and you will scaphoid with the trapezium, the lower position within Mc2 and you can Mc3 points for the capitate, by their much time and you can rounded proximal and you will intermediate phalanges into radiation dos–5.
H1 is differentiated out-of most of the known hominins when you look at the with an effective Mc1 that combines a good mediolaterally slim proximal stop and you may articular aspect which have a good mediolaterally large distal axle and you may lead, a good dorsopalmarly flat and you can firmly asymmetric (that have an expanded palmar-lateral protuberance) Mc1 head, in addition to mix of a total later Homo-eg carpal morphology in conjunction with proximal and you will intermediate phalanges that are significantly more curved than simply most australopiths. H1 as well as differs from almost every other known hominins except H. neanderthalensis in the that have low-pollical distal phalanges that have mediolaterally broad apical tufts (prior to length).
Femur (You.W. 101-1391)
Brand new femur regarding H. naledi differs from the ones from almost every other identified hominins within its fingers out-of several really-laid out, mediolaterally-powering pillars about femoral neck. Brand new pillars run along the superoanterior and you will inferoposterior margins of one’s shoulder and you can establish a definite sulcus collectively their superior factor.
Tibia (You.W. 101-484)
The tibia out-of H. naledi differs from those of all other identified hominins in palms out of a distinct tubercle on the pes anserinus tendon. This new tibia is different from almost every other hominins but H. habilis, H. floresiensis, and you will (variably) H. sapiens within the hands away from a rounded anterior edging.
New ft out-of H. naledi is different from the brand new pedal stays out-of Au. afarensis, Bien au. africanus, and you may Au. sediba in the which have good calcaneus with an excellent weakly install peroneal trochlea. F1 in addition to differs from Bien au. afarensis inside the which have increased positioning of the calcaneal sustentaculum tali. F1 will be further notable away from pedal remains caused by Au. africanus into the having a higher talar lead and you may shoulder torsion, an excellent narrower Mt1 feet, a great dorsally extended Mt1 lead, and greater proximolateral so you’re able to distomedial direction of your own horizontal metatarsals. New H. naledi feet are going to be after that differentiated on ft of Bien au. sediba in the that have a good proximodistally compliment talar trochlea, a flat subtalar mutual, a good diagonally built retrotrochlear eminence and you can a plantar position of your own horizontal plantar process of the brand new calcaneous, and you may dorsoplantarly apartment articular skin on the cuboid toward Mt4 (Zipfel ainsi que al., 2011). Pedal stays regarding Au. garhi are unknown, and the ones out of P. robustus are way too improperly known to accommodate testing.
New H. naledi feet is going to be renowned regarding base away from H. habilis of the presence off a slimmer, non-inclining trochlea that have equally increased medial and you will lateral margins, a narrower Mt1 foot, greater proximolateral in order to distomedial orientation of the lateral metatarsals, and a good metatarsal robusticity ratio of 1 > 5 > cuatro > 3 > 2. Pedal morphology during the H. rudolfensis is currently unfamiliar, hence out of H. erectus is actually improperly known to allow for comparison. Brand new H. naledi base is known on base of H. floresiensis from the a lengthier hallux and shorter 2nd due to fifth metacarpals according to hindfoot duration, and better torsion of your talar head and you will shoulder.
The foot out of H. naledi shall be well-known about ft regarding H. sapiens simply because of the their flatter lateral and you may medial malleolar points toward the latest talus, its lowest perspective off plantar declination of one’s talar direct, their down orientation of your calcaneal sustentaculum tali, and its particular gracile calcaneal tuber.
