Ramayan : Scientific Truths 1

Ref : Article by By Blair A. Moffett


The reference to the "monkey" and "bear" people in the Ramayana simply reflected a straightforward reading of the English translation of the Ramayan of Valmiki made by R. T. H. Griffith, Principal of Benares College, in 1874. The two leading generals of the "monkeys" or Vanar -- Hanuman and Sugriva -- are named there and both play prominent roles in Rama's war against Ravana, the Vanar legions themselves figuring more prominently than do the "bear" legions in alliance with Rama. In fact, in the epic no "bear" is singled out by name, and the "bear" legions appear only relatively anonymously and in second place to the "monkeys." In addition, Rama asks his friend Hanuman to find Sita, his wife, who had disappeared. The loyal Hanuman, at great risk to his own life, and after many adventures testing his courage and intelligence, at last finds Sita who has been kidnapped by Ravana through a trick and taken to his stronghold on the island of Lanka, headquarters of the Rakshasa host.




Inasmuch as the "bears" are depicted as having the same distinctively human qualities as assigned to the "monkeys" in the epic, I think we are justified in concluding that they, too, were some sort of hominid and not a mere animal species such as the bears today. It would have been helpful if the epic had better delineated the "bears," for then we could more accurately analyze if and where they might figure among early hominids! By getting and reading a good translation of this marvelous Indian record of prehistory -- as I think it is -- one can decide for oneself how he or she would characterize the "bear" people.



Turning now to the query: neanderthaloid versus Homo sapiens fossilis, it is true that formerly anthropologists regarded the two types as quite distinct sorts of early men, and the former as hardly a man. This all came about because of a description of neanderthaloids based on the only skeleton then found (in La Chapelle-aux-Saints by the Abbe Bouyssonie), prepared by M. Boule of the Institute of Human Palaeontology in Paris in 1908. That report is now acknowledged by many anthropologists to have done much to disseminate misleading ideas about the whole neanderthaloid question. As recently as 1957 it was still being cited as a major source of information about the nature of the neanderthal man. But in that year the La Chapelle skeleton was re-examined by two anatomists, from Johns Hopkins University and St. Bartholomew's Hospital Medical College of London, who found that it was very atypical, being that of an old male who had suffered extensively from arthritis of the jaws, spine and lower limbs (which had led M. Boule to ascribe to neanderthaloids; a shuffling, ape-like gait with head lowered), and moreover that reconstruction of the skull had been defective. After that expert re-examination, and in the light of some 60-odd fossil skeletal remains of neanderthaloids since found (some 10 of them after 1950), the picture began to change in several major respects.

What Wikipedia says about Neanderthal

The Neanderthal (short for Neanderthal Man, in English pronounced /niːˈændərtɑːl/, /niːˈændərθɔːl/) or /neɪˈændərtɑːl/; also spelled Neandertal) is an extinct member of the Homo genus that is known from Pleistocene specimens found in Europe and parts of western and central Asia. Neanderthals are either classified as a subspecies (or race) of humans (Homo sapiens neanderthalensis) or as a separate species (Homo neanderthalensis).




The first proto-Neanderthal traits appeared in Europe as early as 600,000–350,000 years ago. Proto-Neanderthal traits are occasionally grouped to another phenetic 'species', Homo heidelbergensis, or a migrant form, Homo rhodesiensis. By 130,000 years ago, complete Neanderthal characteristics had appeared. These characteristics then disappeared in Asia by 50,000 years ago and in Europe by 30,000 years ago.Current (as of 2010) genetic evidence suggests interbreeding took place with Homo sapiens between roughly 80,000 to 50,000 years ago in the Middle East, resulting in non-ethnic sub-Saharan Africans (e.g. Caucasians) having between 1% and 4% more Neanderthal DNA than ethnic sub-Saharan Africans.

Classification




First reconstruction of Neanderthal manFor some time, scientists have debated whether Neanderthals should be classified as Homo neanderthalensis or as Homo sapiens neanderthalensis, the latter placing Neanderthals as a subspecies of Homo sapiens.[not in citation given. Some morphological studies support that Homo neanderthalensis is a separate species and not a subspecies.Others, for example University of Cambridge Professor Paul Mellars, say "no evidence has been found of cultural interaction" and evidence from mitochondrial DNA studies have been interpreted as evidence Neanderthals were not a subspecies of H. sapiens.



Neanderthals evolved from early Homo along a path similar to Homo sapiens, both deriving from a chimp-like ancestor between five and 10 million years ago. Like H.sap., Neanderthals are related to Australopithecus, Homo habilis, and Homo ergaster; the exact descent remains uncertain. The last common ancestor between anatomically modern Homo sapiens and Neanderthals appears to be Homo rhodesiensis, named after an archaic Homo sapiens fossil, Broken hill 1 (Kabwe 1) discovered in the territory of Rhodesia in 1921.



Homo rhodesiensis arose in Africa an estimated 0.7 to 1 million years ago. The earliest estimates for Homo rhodesiensis reaching Europe are approximately 800 thousand years ago when a type of human referred to as Homo antecessor or Homo cepranensis already inhabited the region. These two human types may be forerunners to European Homo heidelbergensis, however stone tools dating from 1.2 to 1.56 million years ago of an unknown creator have been discovered in Southwestern Europe. The evidence at the Sima de los Huesos (in the Atapuerca cave system on the Iberian Peninsula) suggest that Homo heidelbergensis was already in Europe by 600,000 years ago.



Molecular phylogenetic analysis suggests that Homo rhodesiensis and Homo heidelbergensis continued to intermix until 350,000 years ago, after which they were separate species and sometime within the last 200,000 years Homo heidelbergensis evolved into Homo neanderthalensis, the classic Neanderthal man. It appears that the original Neanderthal population was in fact more distantly related to today's human than is Homo heidelbergensis. However, recent evidence of successful interbreeding between Neanderthals and modern humans has made that issue moot, at least insofar as some Neanderthal populations were concerned.





The youngest Neanderthal finds include Hyaena Den (UK), considered older than 30,000 years ago, while the Vindija (Croatia) Neanderthals have been re-dated to between 32,000 and 33,000 years ago. No definite specimens younger than 30,000 years ago have been found; however, evidence of fire by Neanderthals at Gibraltar indicate that they may have survived there until 24,000 years ago. Cro-Magnon or early modern human skeletal remains with 'Neanderthal traits' were found in Lagar Velho (Portugal), dated to 24,500 years ago and controversially interpreted as indications of extensively admixed populations.[
