-- "Expanded character sampling underscores phylogenetic stability of Ardipithecus ramidus as a basal hominin"
CS Mongle, DS Strait & FE Grine 2019
These papers
- nowhere contradict the retroviral evidence that human Pliocene ancestors were NOT in Africa,
e.g. C.T.Yohn cs 2005 PLoS Biol 3:1-11, and this RV evidence is 100% confirmed by fossil evidence,
- nowhere contradict our hypothesis that the Gorilla-Homo-Pan LCAs lived in Red Sea forests, google "aquarboreal".
2 interesting papers (JHE), but (like all papers with words like "hominin" & "primitive" & "derived") typically anthropocentrically biased:
they still assume that ape-like = "primitive", and bipedalism = "derived".
They assume no such thing.
They do, my little boy: they assume: Homo + australopiths = hominin. Got it??
That's not an assumption but the result of the phylogenetic analysis.
:-DDD
In your prejudiced eyes perhaps: it's anthropocentric nonsense à la running after antelopes... :-D
All PAs agree: australopith crania were evolving into the Afr.ape direction, specifically
--E.Afr.apiths-->Gorilla,
--S.Afr.apiths-->Pan, e.g.
• “The evolution of the australopithecine crania was the antithesis [!! --mv] of the Homo line. Instead of becoming less ape-like, as in Homo, they become more ‘ape-like’. Cranial proportions and ectocranial features that were thought to be
unique among pongids evolved [also] in the australopithecines ... The features of KNM-WT 17000, therefore, are not as ‘primitive’ as they look. The robust Australopithecus did not evolve from a big-toothed pongid ancestor with large cranial
superstructures, but from a small-toothed hominid with a rounder, smoother ectocranium, like A.africanus”. Ferguson 1989.
• “Plio-Pleistocene hominids had markedly abbreviated [enamel] growth periods relative to modern man, similar to those of the modem great apes”. Bromage & Dean 1985.
• “Enamel thickness has been secondarily reduced in the African apes and also, although at a different rate and extent, in the orang-utan. Thick enamel, previously the most important characteristic in arguments about the earliest hominid, does not
therefore identify a hominid”. Martin 1985.
• In the S.African fossils incl.Taung, “sulcal patterns of seven australopithecine encocasts appear to be ape-like rather than human-like”. Falk 1987.
• “Cranial capacity, the relationship between endocast and skull, sulcal pattern, brain shape and cranial venous sinuses, all of these features appear to be consistent with an ape-like external cortical morphology in Hadar early hominids”. Falk
1985.
• In the type-spm of A.afarensis, “the lower third premolar of ‘A.africanus afarensis’ LH-4 is completely apelike”. Ferguson 1987.
• “A.afarensis is much more similar cranially to the modern African apes than to modern humans”. Schoenemann 1989.
• “Olson's assertion that the lateral inflation of the A.L.333-45 mastoids is greater than in any extant ape is incorrect if the fossil is compared to P.troglodytes males or some Gorilla males and females ... the pattern of pneumatization in A.
afarensis is also found only in the extant apes among other hominoids”. Kimbel cs 1984.
• “Prior to the identification of A.afarensis the asterionic notch was thought to characterize only the apes among hominoids. Kimbel and Rak relate this asterionic sutural figuration to the pattern of cranial cresting and temporal bone pneumatization
shared by A.afarensis and the extant apes”. Kimbel cs 1984.
• “... the fact that two presumed Paranthropus [robustus] skulls were furnished with high sagittal crests implied that they had also possessed powerful occipital crests and ape-like planum nuchale... Nuchal crests which are no more prominent - and
indeed some less prominent - will be found in many adult apes”. Zuckerman 1954.
• In Sts.5, MLD-37/38, SK-47, SK-48, SK-83, Taung, KNM-ER 406, O.H.24 & O.H.5, “craniometric analysis showed that they had marked similarities to those of extant pongids. These basicranial similarities between Plio-Pleistocene hominids and extant
apes suggest that the upper respiratory systems of these groups were also apelike in appearance... Markedly flexed basicrania [are] found only in modern humans after the second year...”. Laitman & Heimbuch 1982.
• “The total morphological pattern with regard to the nasal region of Australopithecus can be characterized by a flat, non-protruding nasal skeleton which does not differ qualitatively from the extant nonhuman hominoid pattern ... in marked contrast
to the protruding nasal skeleton of modern H.sapiens”. Franciscus & Trinkaus 1988.
• “Incisal dental microwear in A.afarensis is most similar to that observed in Gorilla”. Ryan & Johanson 1989.
• The afarensis composite skull (mostly from A.L.333 spms) “looked very much like a small female gorilla”. Johanson & Edey 1981:351.
• “Other primitive [sic =advanced gorilla-like --mv] features found in KNM-WT 17000, but not know or much discussed for A.afarensis, are: very small cranial capacity; low posterior profile of the calvaria; nasals extended far above the frontomaxillar
suture and well onto an uninflated glabella; and extremely convex inferolateral margins of the orbits such as found in some gorillas”. Walker cs 1986.
• As for the maximum parietal breadth & the biauriculare in O.H.5 & KNM-ER 406 “the robust australopithecines have values near the Gorilla mean: both the pongids and the robust australopithecines have highly pneumatized bases”. Kennedy 1991.
• In O.H.5, “the curious and characteristic features of the Paranthropus skull... parallel some of those of the gorilla”. Robinson 1960.
• The boisei “lineage has been characterized by sexual dimorphism of the degree seen in modern Gorilla for the length of its known history”. Leakey & Walker 1988.
• boisei teeth showed “a relative absence of prism decussation”; among extant hominoids, “Gorilla enamel showed relatively little decussation ...”. Beynon & Wood 1986.
• “Alan [Walker] has analysed a number of Australopithecus robustus teeth and they fall into the fruit-eating category ... their teeth patterns look like those of chimpanzees... Then, when be looked at some Homo erectus teeth, he found that the
pattern changed”. Leakey 1981:74-75.
• “The ‘keystone’ nasal bone arrangement suggested as a derived diagnostic of Paranthropus [robustus] is found in an appreciable number of pongids, particularly clearly in some chimpanzees”. Eckhardt, 1987.
• “P.paniscus provides a suitable comparison for Australopithecus [Sts.5]; they are similar in body size, postcranial dimensions and... even in cranial and facial features”. Zihlman et al., 1978.
• “A. africanus Sts.5, which... falls well within the range of Pan troglodytes, is markedly prognathous or hyperprognathous”". Ferguson 1989.
• In Taung, “I see nothing in the orbits, nasal bones, and canine teeth definitely nearer to the human condition than the corresponding parts of the skull of a modern young chimpanzee”. Woodward 1925.
• “The Taung juvenile seems to resemble a young chimpanzee more closely than it resembles L338y-6”, a juvenile boisei. Rak & Howell 1978.
• “In addition to similarities in facial remodeling it appears that Taung and Australopithecus in general, had maturation periods similar to those of the extant chimpanzee”. Bromage 1985.
• “I estimate an adult capacity for Taung ranging from 404-420 cm2, with a mean of 412 cm2. Application of Passingham’s curve for brain development in Pan is preferable to that for humans because (a) brain size of early hominids approximates that
of chimpanzees, and (b) the curves for brain volume relative to body weight are essentially parallel in pongids and australopithecines, leading Hofman to conclude that ‘as with pongids, the australopithecines probably differed only in size, not in
design’”. Falk 1987.
• In Taung, “pneumatization has also extended into the zygoma and hard palate. This is intriguing because an intrapalatal extension of the maxillary sinus has only been reported in chimpanzees and robust australopithecines among higher primates”.
Bromage & Dean 1985.
• “That the fossil ape Australopithecus [Taung] ‘is distinguished from all living apes by the... unfused nasal bones…’ as claimed by Dart (1940), cannot be maintained in view of the very considerable number of cases of separate nasal bones
among orang-utans and chimpanzees of ages corresponding to that of Australopithecus”. Schultz 1941.
IOW, all fossil hunters agree 100% on apith evol.directions:
-- afarensis-->boisei-->Gorilla,
-- africanus-->robustus-->Pan.
My hypothesis:
Plio-Pleist.Gorilla evolved in the incipient northern-Rift in // with Plio-Pleist.Pan in the incipient southern-Rift
(meanwhile, as shown by the retroviral DNA, Plio-Pleist.Homo was in S-Asia-->Java, of course),
fully comparable IMO to the late-Miocene hominids s.s. evolving in the incipient Red Sea.
These incipient rifts were very rich in swamp forests, where early hominids had to
- wade bipedally in the swallow water between the trees &
- climb vertically in the branches above the water, arms overhead
(explaining the transition from above-branch monkeys to brachiating apes).
IOW, only complete idiots deny that Afr.ape ancestors were bipedal waders-climbers,
google "aquarboreal":
this is comparatively & anatomically obvious, except to idiotic antelope runners, of course... :-DDD
Some kudu runner:
Australopiths turn out to be a paraphyletic group of succesive
stemtaxa to Homo.
"paraphyletic to Homo" :-DDD
Never do afarensis and boisei turn out to be sistertaxa of Gorilla,
and never do africanus and robustus turn out to be sistertaxa of Pan,
which would have to be the case if they are the ancestors of Gorilla
and Pan respectively. Blame the computer.
Sigh!
My little little boy, the above quotations (of traditional PAs!!) show:
- boisei was more gorilla-like than Lucy,
- robustus was more chimp/bonobo-like than Taung.
Okidoki??
IOW, they became less+less humanlike!
Okidoki??
It's really not difficult at all (even I can understand),
but you have to get rid of your ridiclous Afro+anthropocentric prejudiced nonsense!
Already caught your kudu??
with or without sweating water+sodium?? :-DDD
Onnozelaars.
