National History Symposium of North Korea 2016

On the 28th of November 1976, Eternal Leader of North Korea, Kim Il Sung, ordered the Kim Il Sung University to investigate the origins of the Korean people. Since then, both Kim Il Sung and his son Kim Jong Il have proposed hypotheses to explain the origin of the Korean people and their history. On the 28th of November 2016, exactly 40 years later, a National History Symposium was held in Kim Il Sung University to take account of all the research that had been conducted within the country until now.

The outside world has not been informed of these advances to a very clear level, but what we do know is that there is evidence that the Korean peninsula featured hominins by about the Upper Palaeolithic. According to the Pyongyang Times, Korean ancestors had settled down in the Taedong Basin around the present day capital Pyongyang “at the dawn of human history”.

The ‘Black Hole’ of Palaeoanthropology – A Message For Isis

The ‘Black Hole’ of Palaeoanthropology is not a term you hear very often, but then again what is there to say about the biogeographic history of a 1.77 million square kilometer region (Turkey, Saudi Arabia, and Iran) with virtually no faunal, human or archaeological sites. At this point it would seem easy to resign yourself to the words of Timothy D. White at the dawn of the 21st century, that we are not going to find many more fossil hominins. The mark of a great palaeoanthropologist is to never give up that curiosity for the unknown. Since White’s depressing prediction, he has been roundhouse kicked to Wrongville, with the spectacular finds of Ethiopia, South Africa, Myanmar, China, Flores and much much more. We have learned so much thus far, don’t lets forget this. Sounds great but these inevitably throw up more questions than answers. And the ‘Black hole’ is a particularly hard nut to crack. middle_east_graphic_2003

What does archaeology have to offer? Ethiopia features the earliest concrete evidence for hominin stone tool manufacture. At 2.6 million years of age it predates the earliest known human – Homo habilis – by less than 300,000 years years (Fossil Code: A.L. 666). Saudi Arabia has a rather rich representation of Mode 1 (Oldowan) stone tool clusters. If you don’t know to millimeter accuracy where the stone tool was found, or if it is a surface find then it is worthless to science.  The Saudi sites were also used during the Holocene (11,700 years ago to present), begging the question how can you separate Early Pleistocene (2.5 million years ago to 700,000 years ago) from Holocene activity? At least we can tell that hominins took one route out of Africa. Stone tools similar to the Oldowan found at Perim Island supports the hypothesis that early hominins crossed the Bab al Mandab Strait (20 miles wide). Iran has probably the most depressing lack of archaeological evidence of the region. Isolated finds dominate, both the Oldowan and Acheulean records of Iran and few excavations have taken place. South of the Caspian Sea is the site of Ganj Par, which yielded 100 limestone tools within half a hectare. This assemblage shares similarities with those of Ubediya, Israel and the Oldupai Gorge (also known as the Olduvai Gorge), Tanzania. Turkey repeats much the same story. Of the 200 Palaeolithic sites, less than 25 have been even partially excavated. The majority are restricted to the fringes of the Anatolian plateau.  None are any older than 1.3 million years of age, further supported by Argon-Argon dating of Kula, western Turkey to 1.24 million years of age. The site was the location of a palaeomeander which contained a solitary Quartz flake, 5 x 4 cm. Volcanic activity interfered with the palaeomeander and it was that lava flow that allowed the date to be so accurate. The take-home-message from Turkey is the earliest securely dated archaeological remains support the 1.1 million years calculated for the Kocabas skullcap, which shares affinities with OH 9 and KNM ER 3733, attributed to H. erectus. Debate continues as to its taxonomic status, but it does reflect a great deal of H. erectus characteristics. The Archaeology tells us that hominins with the ability to make stone tools were already out of Africa 1.8 million years ago, at the site of Dmanisi, Georgia.Untitled-2

It is the richest fossil hominin location at the ‘black hole’ fringe. The Fall of 2013 was just another milestone in sites long history of archaeological investigation. The discovered cranium (D4500) was reunited with its jaw (D2600) and the team of palaeoanthropologists led by David Lordkipandize  concluded that the five individuals represented members of the same species, but retracted the classification of D2600 (Homo georgicus) for Homo erectus ergaster georgicus. This raised some eyebrows in the palaeoanthropological community, particularly Fred Spoor, palaeoanthropologist and lecturer at the UCL Department of Anthropology,  who pointed out that such an action is not outlined in the code of zoological nomenclature. This is a minor debate in the palaeoanthropology, but most agree that Homo erectus exhibited a variation comparable to that seen in modern Homo sapiens today. Dmanisi is proof that hominins were already out of the African continent by 1.8 million years. Additionally, although the dating of the hominins of Java are in the doldrums, these specimens could be as much as 1.8 million years of age. Prior to that time some hominin species made it’s way north, but which one?

On the 23rd of January 1995, a French-Chadian team of palaeontologists discovered a fragment of fossil jaw (Fossil Code: KT 12/H1) lying on the gravel desert of northern Chad. The fossil (nicknamed “Abel”) could not be accurately dated, nevertheless stratigraphic layers nearby suggested it could as much as 3.5 million years of age. Back then, the river Bahr El Ghazal flowed into a 3 million square kilometer lake called Megachad.  This hominin foraged on grasses that dominated the Koro Toro region. The palaeontologists gave “Abel” a new species name – Australopithecus bahrelghazali distinguishing it from another australopithecean – Australopithecus afarensis. That species lived in the eastern region of the continent, over 2,500 km from the Bahr El Ghazal site. The animal remains found in the stratigraphic layers of both regions were pretty much identical, which means the ecosystems were the same. Therefore, you can see why some palaeoanthropologists consider it plausible that “Abel” is just another Au. afarensis. This goes back to the argument that, what we are looking at here is just another variation of the same species. Either way, here we have australopitheceans in eastern and north central Africa. Theoretically, it is plausible for australopitheceans to have made their way into Arabia.

Every organism has a landscape format that they thrive within. Lions are quite at home in the savannah, Tigers frolick in the dense jungles of the Indian subcontinent and hominins, particularly australopitheceans, were quite at home in savannahs. If we are to prove that they made their way into Arabia, there should be an extension of savannah into the Eurasia 3-4 million years ago. Sadly we are not seeing this, but what do we see. The faunal record of Saudi Arabia is particularly fragmented and sparse. Western Turkey (Calta) 2.3 million years ago, saw Raccoons, Giraffes, Hippos and the extinct “Running” Hyena. Many associate Bethlehem with the Christian story, but few know that at about the same time, this region featured Raccoons, Sabre-Toothed Cats, Rhino, an ancestor to the Mammoth and ancestor to the modern boar. While 110 kilometers north of Bethlehem and 700,000 years later, Baboons lived south of the Lake of Tiberias, around Ubeidiya. Lakes were magnets for faunal activity and therefore hominin activity.

The An Nedfud desert of northern Saudi Arabia is classic wilderness today, 2 million years ago it was the hub of a diverse ecosystem with a lake as the centrepiece. The faunal remains were recovered from three localities and share similarities with the kind of fauna you would expect at Ubeidiya and the Oldupai Gorge. Hippos were found at these sites and since modern day counterparts prefer standing water to a depth of 5 meters, it gives an initial sense of the size of ‘Lake An Nedfud’. A lake capable of supporting fish life, but this is not the only lake to have supported faunal biodiversity in the ‘Black Hole’. ‘Lake Negev’ developed around 1.8 and disappeared around 1.5 million years ago under ever increasingly arid conditions. It supported fish populations and laid down 15 m thick sediments over 18 sq km². Besides these lakes, there were smaller lakes, Oases and springs that would have allowed hominins to hop, skip and jump out of Isis territory and into the more accommodating environments of Europe and eastern Asia. Looking at the faunal remains you can get a sense of the climate that prevailed at whatever time period you are interested in. The climatic mapping of the Pliocene and Early Pleistocene of the ‘Black Hole’ are, you’ve guessed it understudied. We do know that two and a half million years ago, the forests of Azerbaijan gave way to Savannah and the Arabian peninsula experienced 2 million years of humid conditions, capable of keeping many large (now extinct) rivers topped up.

There you have it. We know alot, but we know so very little about this massive region of the world. We lack fossil hominins in this region and I don’t think Isis would be willing in finding their early ape ancestry any time soon. It would definitely be a useful distraction from Wahhabism. Do something useful for a change, Isis! Get out there and find us those damn fossils! You ignorant misogynistic apes!

Meganthropus palaeojavanicus – The Early Years of Palaeoanthropological Research (1942 – 1955)

Meganthropus palaeojavanicus (from the Ancient Greek, meaning Ancient Java’s Great Human) is a redundant genus and species that was first formally introduced by Gustav vonKoenigswald (1902 – 1982) in 1950. The genus once referred to a set of fossils found on the island of Java in the 1930’s, 1940’s, 1950’s and 1980’s. The Javan fossils are now attributed to the hominin Homo erectus that lived from 1.9 million years ago to 300,000 years ago and had a range from Africa to Eurasia.

On the 15th of January 1942, the Director of the Geological Survey of the Netherlands Indies, W. C. B. Koolhoven wrote a letter to anatomist and palaeoanthropologist, Franz Weidenreich informing him that vonKoenigswald wishes the 1939 and 1941 to be attributed to a new genus and species of ape called M. palaeojavanicus. In 1945, Weidenreich referred to it as “vonKoenigswald’s Meganthropus palaeojavanicus”. Held in the Senckenberg Forschungsinstitute und Naturmuseum, an unpublished 1949 scientific paper written by vonKoenigswald proposes that Sangiran 1a,  It was not until 1950, the vonKoenigswald committed his new genus and species to print in a formal introduction. As the sixth decade of the 20th century developed, consensus shifted towards H. erectus as the taxonomic appellation of the Javan fossils.

“Meganthropus” Fossils

The following are a list of fossils that were taxonomically assigned to Meganthropus, but have now been officially assigned to H. erectus

Franz Weidenreich (1873 – 1948)

Sangiran 6a

Kromopawiro (a team member) discovered the fossil adult mandible fragment “near Glagahombo, north of Sangiran” not far from where another cranium was uncovered in 1939 and south of Sangiran 4’s location. Weidenreich described the 1.6 million year old fossil in 1945, in which he pointed out the size of the mandible and the primitive premolar morphology as evidence to support the application of a new genus and species – M. palaeojavanicus. This conclusion was revised in 1989, when Kramer concluded that the size was within the size range of H. erectus.

Sangiran 7

Dating to between 1.51 and 1.6 million years of age, Sangiran 7 (comprising 54 teeth) was recovered from 1937 to 1941. Fred Grine analysed some of the teeth in 1984, but it would be a decade later before he revised his earlier conclusion that they were hominin. As a result, three teeth FS 67, 72 and 83 were re-attributed to Pongo sp.

Wilfrid Le Gros Clark (1895 – 1971)

Sangiran 8

Uncovered in 1952, Sangiran 8 comprises fragment of mandible, with some teeth roots intact and a complete third molar crown. This individual is interpreted to have died in the jaws of a crocodile, based upon the scare marks on the fossil. The fossil was first described in 1953 by P. Marks concluding it lay outside the size range of H. erectus. In 1955, Le Gros Clark concluded that the fossil was within the range of H. erectus and that has remained the official attribution for Sangiran 8 ever since.

Sangiran 27

This partial adult cranium was first found in 1978 near Sangiran village, north of the River Chemoro and it was found as construction was underway on a new dam. The skull was found in the upper levels of the Sangiran Formation dating to between 1.66 and 1.58 million years of age. The fossil was described by Teuku Jacob in 1980, in which he attributed it to Meganthropus but was taxonomically revised in 2008 for reasons similar to the taxonomic revision of Sangiran 8. Indriati and Anton (2008) also noted that hyper-robust features of the fossil reflects earlier representatives of H. erectus.

Modern Uses of Meganthropus

Though taxonomically and scientifically redundant, Meganthropus is used by pseudoscientific Creationists as evidence for the Nephilim, giants that lived before Noah’s flood, referenced from an Iron Age manuscript called the “Book of Enoch”.

Norandino and Lucina Discovered by the Ogre (1624) – Giovanni Lanfranco (1582 – 1647)

A trickle of scientific papers and posters have been published and presented over the decades, claiming evidence for Meganthropus. Authors have suggest that Sangiran 5 is evidence of the existence of an older, “more robust morph”, with pongo-like characteristics. Suggesting that a Gigantopithecus-like counterpart lived in island South-East Asia. The most recent appearance of support for Meganthropus was at the 83rd annual meeting of the American Association of Physical Anthropologists in 2014, a team of scientists led by Clement Zanolli presented a poster on their analysis of a fossil mandible fragment code named Arjuna 9. They suggested that teeth had enamel thickness and dental tissue proportions that differed from those seen in H. erectus. The statistical analysis of the enamel-dentine junction also seemed to support an attribution to Pongo sp. The fact remains, no evidence exists to support classifying the Javan fossils as Meganthropus.

Abel Lived 3.5 Million Years Ago Along The Shores of Megachad – Australopithecus bahrelghazali

On the 23rd of January 1995, a team of palaeontologists discovered a fragment of fossil jaw lying on the gravel desert of northern Chad. The fossil could not be accurately dated, nevertheless stratigraphic layers nearby suggested it could be around 3.5 million years of age. Back then, the site of Koro Toro was on the edge of africa-11117a 3 million square kilometre Lake called Megachad. The fossil, now codenamed KT 12/H1 consisted of the front portion of the jaw with a number of teeth still in place. By using Isotopic analysis the diet of the hominin shortly before it died, can be determined. The fossil showed a preference for C4 plants, including sedges and grasses, suggesting that the area around Koro Toro was predominantly grassland. Comparing the fossil to other hominins, the features were considered very different compared to Australopithecus afarensis, 2,500 km away in Ethiopia and Kenya. The French team, led by Michel Brunet, concluded the fossil was part of a new species of AustralopithecusAustralopithecus bahrelghazali. This caused a bit of a stir in the palaeoanthropological community, but progressively began to die down. The lack of fossil finds in Chad thereafter contributed to the rate at which the palaeoanthropological community forgot about the fossil, that was, until 2001. Given the same variety of animals can be found in both Ethiopia and Chad, it is not a stretch to imagine australopithecines travelling between the two regions three million years ago and many palaeoanthropologists now consider the fossil, a variant of Australopithecus afarensis.

How did the fossil make palaeoanthropologists rethink their understanding human evolution? “Abel” as the fossil became to be known reminded palaeoanthropologists that human evolution could have been more complex than previously accepted. Though once you considered the features of an Australopithecus afarensis jaw and compare that to “Abel”, it is acceptable to attach it to the Ethiopian hominin. The differences are subtle. It is worth reminding here however that the use of species names don’t tell us much about the hominins palaeobiology, are primarily to put, order to our understanding of evolution and are a useful means of scientific communication. Palaeoanthropology has had a long history of naming new species, when later we realize we were too optimistic. In the sense, that we forget how useless this venture is. More is learned from the fossils, about a hominins diet, locomotion patterns and physical characteristics than what species it belongs too. Thankfully, science is less focused on this and we are now learning much more about the hominin and the ecosystem it was once a part of. The second way in which “Abel” got us thinking, was via the surprise geographic location. Up until that time, any fossil finds made on the continent of Africa were made exclusively in eastern and southern Africa. “Abel”, reminded us that hominins were not just restricted to those regions and likely could be found all over Africa. Exciting though this prospect was, it could not solve the problem of preservation in areas where fossils cannot survive, in the hostile environments of the Sahel.

Eventlog – 15th of January 1942 – Dawn and Demise of Meganthropus palaeojavanicus

The History of Palaeoanthropology is dominated by an obsession of applying new latin genus and species names to nearly every fossil that made its way into scientific scrutiny. With the passing of the 20th century, this obsession dissipated as scientists began to realise such preoccupations were redirecting some much needed attention away from many important relevant questions. Today’s Eventlog reminds us of what had been. But first let me introduce three gentlemen.

W. C. B. Koolhoven was a Dutch Director of the Geological Survey of the Netherlands Indies. Franz Weidenreich (1873-1948) was a german anatomist and palaeoanthropologist, based for much of his life in Beijing, China and had a long association with the Homo erectus fossils of Zhoukoudian, China. Finally, let me introduce Gustav Heinrich Ralph von Koenigswald (1902-1982) a german palaeontologist, geologist and Palaeoanthropologist. Interested in geology and fossils from a young age, Gustav vonKoenigswald worked in Java propecting for hominin fossils. The Dutchman and two germans crossed paths in discussions about two Javan fossil mandibles. The debate centred around the size of the mandibles, which at that time seemed too big to be attributed to Homo erectus.

And so on this day the 15th of January 1942, Koolhoven wrote a letter to Weidenreich letting him know that vonKoenigswald was keen to attribute Sangiran 5 and 6a to Meganthropus palaeojavanicus. It would be eight years before vonKoenigswald would introduce the new genus and species formally. Over the next few decades, M. palaeojavanicus began its slow dissolution from scientific discourse, replaced by the hominin Homo erectus.

Discovery of the Paranthropus of Peninj

This evening on the 11th of January 1964, fossil hunter Kamoya Kimeu (1940-Present) was crossing what had been an Early Pleistocene delta to the western side of Lake Natron, Arusha, Tanzania. He was there with a team led by Richard Leakey in search of our earliest ancestors. Barely a few days into the expedition, Kimeu found a hominin mandible, not one of our ancestors, but just an intriguing. It is 1964 and by this time, OH 5, representative of Paranthropus boisei was already gracing the covers of magazines throughout the world. Thought to be the first human that used stone tools for the first time, the Nutcracker Man was not all he was cracked up to be. As more hominin fossils from the Late Pliocene and early Pleistocene began to show, it became more and more clear, that while P. boisei may have been found on an archaeological layer, this is not enough evidence to support a “he’s the first human” hypothesis.

Ol Doinyo Lengai: A View from Lake Natron

Kimeu had found another representative of P. boisei at Peninj and it was a remarkably complete hominin mandible. The right condyle was missing and so too were the left and right coronoid processes, despite that the fossil had its complete set of teeth and that was particularly key. The teeth showed a great deal of wear  to the point that you could see the dentine beneath the enamel. This individual must have eaten alot of sedges and grasses throughout its life to give that sort of result. Grasses and sedges that you could find around deltas like that one that would have entered Lake Natron, when it wasn’t quite as salty. But when exactly did our hominin friend give up its spirit along the shores of the Lake. The stratigraphic layers in the region are like the pages of a picture book, no words, but pictures that can tell better narratives that Twilight could ever even dream of. The mandible was uncovered in a sedimentary layers, comprising the deltas alluvial deposits, sandwiched between two volcanic layers. The volcanic Tuff atop the layer that contained the fossil was previously dated to between 1.6 and 1.4 million years of age, while the basalt below was dated to 1.7 million years of age. You may think that the fossil is probably going to be between 1.7 and 1.4 million years of age, but the team of geologists at the site conducted further analysis at the site to help get a more accurate result. They settled on an age for the mandible of between 1.5 and 1.3 million years of age. Enough time for the ph of a lake to reach beyond 12.

Since the discovery of the Peninj 1 mandible in 1964, another hominin with similar characteristics to P. boisei was found. Paranthropus aethiopicus now joined a trio of hominin species that became the Paranthropines, comprising boisei, robustus (South African hominin) and aethiopicus. Most of what we have collected of these creatures are crania and mandibles, though some postcranial remains have been found. Thankfully the teeth survive well and can tell us a great deal about their diet and the subtle, yet important questions of how they chew their greenery. There was a long drawn out debate over whether these three hominins deserved to live in a separate group – the Paranthropines. Originally, these hominins were classified as robust australopithecines and the palaeoanthropological community decided that a change was needed. The complete anatomy of the Peninj Hominin was never recovered and given that the mandible survived so well, this individual may have fallen to a carnivore in the delta. Below is a summary of the discovery that was made on the 11th of January 1964.
