0. Most educated people have at least a rough idea, of what 'Indo-European' (IE) languages are: They are the many languages linked by shared inherited vocabulary (e.g., number system, pronouns) and grammar that are spoken from northwestern Europe to the Indian subcontinent (historically even to Xinjiang in northwestern China). Basic information can be found in all recent encyclopedias, the relevant Wikipedia pages are inferior. One has to warn against the many websites of unserious, esoteric crackpots without the necessary background knowledge in Indo-European studies, archaeology, and statistics (for more see Holm 2007b passim), often recognizable by citations of few secondary sources or even racial nonsense.

1. What is still being argued about here, above all, are the origins and pre-historical developments of this language family, in chronological, geographical, and recently also population genetic terms. In these discussions we repeatedly encounter the superficial assumption that languages are all the more closely related the more features they still have in common, without noticing that these are determined, among other things (!), by the kinship-independent substitutions after the respective separation (see Holm 2003). It should really be understandable that languages with heavy losses (as e.g. Albanian or Armenian), in spite of a close relationship, simply because of their smaller data base, share lesser agreements than so-called Large-Corpus Languages like Greek or Indo-Aryan.

1.1. This quantitative problem can only be solved by observing the - here hypergeometric - data distribution, which is indispensable in statistics. Through such a distributional "SLRD transformation" (for, Separation Level Recovery accounting for the Distribution), we estimate the original feature set to be assumed in the period of separation of each pair of languages, in short "separation set". These figures, for the 91 pairs between 14 attested branches of IE, have been published in Holm (2000).

1.2. Since the number of original linguistic features can only decrease over time, e.g. due to historical influences, a clear separation sequence (not "glottochronology") emerges, illustrated by a so-called >"family tree", here exemplified by the respective oldest form of the words for 'hand' in the twelve main branches of the Indo-European language family. Of course, this spin-off sequence represents only a scheme and must then be applied to the various conceptions of the original staging area or "Urheimat", including the necessary migratory movements.

1.3. The early contacts of the Indo-European languages with the Uralic languages, linguistically deduced as loanwords or even hereditary features, suggest an original home in the Eurasian (forest) steppes. My suggestion for the migrations to be assumed starting from there is given by this >dispersal map. It should be noted, however, that the migratory routes have not been convincingly proven to date.

2. On the question of time: if we reckon back chronologically from the earliest attested appearance of the Hittites, it seems clear that the spread of Indo-European languages occurred roughly in parallel with the spread of metallurgy, ox teams, and mounded tombs. Which does not necessarily mean that the Indo-Europeans invented these techniques and customs, but at least used them intensively. As pastoral nomads with a high proportion of horses, they should also have been good horsemen. This in turn gave tactical advantages in raids and warfare. At the beginning of horse riding one probably had bitless or only non-metallic and thus archaeologically hardly provable bridles, thus to date earlier than the bit wear provable only with the emergence of metal snaffles. Since all these inventions are not compelling, but only conducive conditions for migrations, the latter could have taken place both in a shorter time, or even a little earlier or later.

3. Another point of disagreement and discussion is the question whether the so-called Anatolian languages, in particular Hittite,
- were full members of Proto-Indo-European
- or the latter had achieved its complete development only after the separation of Hittite.

4. The currently fashionable phylogeny reconstructions by mechanistic application of computer program packages from the field of biological systematics often tend to at least one of the following erroneous beliefs:
4.1. Some cladistic researchers simply assume a priori that Hittite did not share the final development of IE, use this language as a so-called "outgroup", and are then subject to the circular argument that Hittite is the natural starting point of their originally rootless (!) graph.
4.2. They follow the primitive similarity principle - languages are said to be closer related the more "cognates" they share (erroneously equated with 'evolutionary distance'), in complete disregard of the real dependencies presented in [1] ('proportionality trap' - cf. Ref. Holm (2003)).
4.3. Or even the assumption that words would be exchanged "by the clock" , which is obviously wrong and only continues initial errors of glottochronology: Look up any word in an etymological dictionary and find the reason for its existence: it will never be 'time', but historical (e.g. cultural, technical, military) events, which nobody ever can foresee = compute: E.g. English did not replace about 50 % of its originally Germanic vocabulary 'by time', but, as educated speakers of English know, by Norman dominance after the battle of Hastings, besides a long-lasting educational background of Latin. That in lexicostatistical test vocabularies the amount of changes is gradually lower, does not at all change the socio-historical reasons and causes, in particular their uncomputability. Even in Swadesh's 100-word test list of English, 6% are loans from Viking dialects (cf. Holm 2007c). Journalists cannot be blamed for not understanding what really is going on in these computations. But scientists should be expected to look for backgrounds and causalities instead of blindly adopting these mechanistic comparisons.

N e w ! - Did the Proto-Indo-Europeans invent the Wheel?
[Abstract: The role that the cartwheel played in the life of the Indo-Europeans has primarily been studied from the perspective of specialists, often without sufficient consideration of the other fields involved. Therefore, we research an archaeological list of the oldest wheel finds (before ca. 2000 BCE) with regard to the most accurate dating, location, and construction type that now contains 130 representative finds between the North Sea, Central Asia, and India. We then elaborated the five wheel designations in the Indo-European main families, espe- cially in terms of onomasiological aspects. In order to relate both results to the development of the Indo-European languages, chronological scaffolding is needed, for which we bring in a recent glottochronological calculation of the Indo-European subdivisions. This already leads us to conclusions about the age of some designations, as well as clear parallels to certain construction types. In addition, on this updated basis, two often-discussed questions are addressed. With regard to the separation of the (Indo-European) Anatolians and Tocharians, there are many indications that this had taken place around the Caucasus from the eastern primary branch. Finally, the hypotheses for the “invention” of the wheel are replaced by the far more realistic one of a long-lasting development in a wide communicational area.] Correction: I apologize for the typo in footnote 5, please correct the Name to S(usanne) Kuprella.

[Abstract: Despite dozens of hypotheses, the origin and development of the Indo-European language family are still under debate. A glottochronological approach to this problem using Bayesian computation of language divergence dates (appeared in Science 2012/2013) claimed to have provided evidence for the period of Neolithic expansion, known as the "Anatolian hypothesis". The dates have met with considerable criticism from other disciplines. I decided to investigate the alleged evidence for these dates by replicating and analyzing the approach with an own, updated dataset. This initially resulted in an origin around 4800 B.C., although the structure of the pedigrees varied considerably in several hundred tests. This problem was avoided in previous approaches by rigorous topological forcing. Here we applied a west-east dichotomy from a previous purely lexicostatistical (i.e. without times) approach based on the best available Indo-European dataset of approx. 1,100 verbal roots, which then produced dates around 4100 BC. During these tests, a further approach (Language, 2015) located a date of origin from between 3950 - 4740 BC. One of the insights of that study was that previous results were significantly disrupted by poorly attested languages, which thus were consistently removed step by step. These dates reflect the most recent state of knowledge in linguistics, archeology and genetics in favor of the Steppe hypothesis. A new archaeological-linguistic comparison of the wheel terminology, a primary argument for the divergence date, shows that different Indo- European denotations coincide in different areas with different types of wheel-axle constructions. Finally, the cultures lying on the possible dispersal routes and times are superimposed as an overlay on the calculated phylogenetic tree, without, however, postulating their Indo-European character in every case.]

[Abstract: In the last decade, several scholars claimed to have finally solved the subgrouping of Indo-European by new lexicostatistical attempts. The public of course was not able to perceive the questionable outcomes, of which the different and idiosyncratic positions of Albanian are particularly conspicuous. One reason for this is the inadequate methods, simply copied from bioinformatics (cf. Holm, H. J. 2007). That defective data may contribute a great deal to these mistakes, is now first demonstrated here by analysing the Albanian part of three representative lists frequently employed in these studies: Thirteen percent of the data on these lists contains errors and this mixes inextricably with the overlooked stochastic dispersion. Seventeen new etymologies are proposed; however, about thirty per-cent of the list remains unsolved or questionable. Moreover, the high amount of differently changing replacements in Albanian is one more compelling argument against the rate assumption in glottochronology.]

[Abstract: Schmidt/Gruhle present with their so-called "growth homogeneity" - here: by central European oak sites - a good indicator for wet-warm versus dry-cold years. This proves at least for the North Atlantic region, among other things, by the relatively good correlation both with the fluctuations of the tree borders in the Alps and with the temperature courses readable from Greenland ice core drillings. In contrast, the claimed good correlation with solar radiation (insolation) turns out to be the result of too short-term considerations or even erroneous interpretation of solar activity.]

[Abstract: Linguists use to assume that languages were closer related, the more features, in particular common innovations, they share. In Holm (2003) has been demonstrated that this assumption is erroneous because these researchers miss the fact that the amount of shared agreements depends stochastically upon three more parameters. Only by help of the maximum likelihood estimator of the hypergeometric distribution we are able to find the amount of features, which must have been present in both languages at the era of their separation. This way we obtain a chain of separation between a family of languages for which the appropriate data is available. When applied to data of the Pokorny IEW, the resulting late separation of Hittite, Albanian and Armenian could well have been caused by their central position and therefore did not appear suspicious. Only when in a further application to Mixe-Zoquean data the same observation occurred that poorly documented languages appeared to separate late, a systematic bias could be suspected. This work reveals the reason for this bias peculiar to lists of natural languages, as opposed to stochastically normal distributed test cases like those presented in Holm 2007a. As more modern and linguistic reliable database the new "Lexikon der indogermanischen Verben", 2nd.ed. (Rix et al. 2001) was the best choice. Indeed the suspicion was confirmed and it is shown how these biased data can be correctly projected to true separation amounts. The result is a partly new chain of separation for the main Indo-European branches, which fits well to the grammatical facts, as well as to the geographical distribution of these branches. In particular it clearly demonstrates that the Anatolian languages did not part as first ones and thereby refutes the Indo-Hittite hypothesis.]

Bird's "Distribution of Indo-European root morphemes" (Wiesbaden: Harrassowitz, 1982) it became possible, in spite of its known shortcomings, to estimate the amount of lexemes having been present at the era of separation for every pair of sister languages with help of a robust estimator, and consequently to conclude upon the chain of separations.]
