Similarly, the variance of the body height also follows an inverse gamma distribution with parameters a Rel. To check for convergence, the Gelman-Rubin diagnostics was computed which was well below the value of 1. Within the resulting tempo-spatial model, we can calculate body height for every location and point in time within the study area and time, i.
For visualization and evaluation of the results for long bone lengths and estimated body heights, two cross-sections of the spatiotemporal models were chosen:. In accordance with the broad progress of Neolithization, here, we have chosen Fig.
Exemplary points in the study area selected for the visualization of regional time trends of the models. By borrowing strengths from nearby times or regions where- and whenever data coverage is insufficient, the Bayesian errors-in-variables approach taken is able to produce continuous staturescapes for all ten models Figs. While unmodeled results for the respective regions such as Angel ; Bennike ; Jaeger et al.
The reduction of relative importance of the Iron Gates data in our model for the Central Balkans D , for instance, leads to a significantly lower impact of the Neolithic on stature than the unmodeled data Rosenstock and Scheibner suggests. All ten models Figs. While the Atlantic forms a natural edge of data, this situation could theoretically be alleviated for the East and South of the study area by adding more data from further East and South, but for Northern Europe, not much more data is to be expected due to preservation issues.
Moreover, in reading the models, it must be kept in mind that geographical boundaries such as seas, rivers, and mountain ranges and cultural thresholds, e. There are some approaches for hard, insurmountable frontiers e.
In general, all four bone lengths appear to follow an East-West gradient for both sexes with longer bones in a zone stretching from Eurasia into the Eastern part of the Fertile Crescent and shorter bones towards the West of the modeled area.
F1 Fig. Likewise, T1 Fig. Bone lengths develop concordantly in almost all regions except the Fertile Crescent A. Here, F1 declines from approx. Humerus and radius not only behave in opposite patterns for males and females but are also at odds with the lower limb bones Supplement 4. These inconsistencies in the Near East A might only be a fringe effect of lacking data further East and South s.
That Western, Northern, and Eastern Europe A, B, C, L, and K are also likely to be subject to fringe effects in the data and do not show such inconsistencies, however, makes it more likely that the model either suffers from the low number of observations in the Near East Figs.
Interestingly, femur and humerus lengths stagnate in Eastern Europe, whereas tibia and humerus lengths decline. In the Iberian Peninsula I , the overall decline in bone lengths is quite marked. The later Holocene in most regions except the Pontic Steppes K is characterized by a slight increase of bone lengths. For the most part, comparison of the ten generated models Figs.
Despite the low statistical weight given to them, trends in the model for estimated stature data from sample B are considerably more pronounced in comparison to sample A. Apparently, quality of the underlying data must be traded off against the quantity of the underlying data. General trends, which we were aiming to detect with our model, however, remain robust irrespective of the method chosen. After all, our preferred stature estimation method is our modification of the Ruff et al.
The general East-West gradient already visible in the individual bone data is corroborated in the stature models. In the Pontic Steppes K , males and females were very tall throughout, whereas towards the South and West, stature was significantly shorter. In almost the entire study area, early Holocene stature stagnates or declines only slightly. In the Fertile Crescent A and Anatolia B , a decrease is only visible from the 8th millennium onwards and reversed in the 5th millennium.
While the Aegean C shows stable stature, stature declines in the Balkans D in the 8th to 6th millennium. In Central Europe E , stature remains stable until later prehistory brings about an increase which is especially marked in sample B, mirroring a trend also visible in the rest of Europe, which is particularly strong in Northern Europe after ca.
Large credible intervals indicate that the increasing stature in the early Holocene of Northern and Western Europe F, G, J might only be an artifact of the small sample size, but still these regions stand in contrast to Southern H, I Europe characterized by a decline in stature in the early Holocene.
The tempo-spatial picture of stature variation in the Near East and Europe ca. The existence of an East-West gradient in body height at the onset of the Holocene corresponds with evidence for several genetically distinct populations brought about by the last glacial with its severe climatic conditions Haak et al.
Longest bone lengths and tallest stature in the Pontic Steppes and the declining trend in the Iberian Peninsula already noted by Lalueza-Fox not only confirm expectations derived from a genetic study on potential body height in these regions Mathieson et al.
Formicola and Giannecchini already observed stagnating to slightly declining stature in the early Holocene of the rest of the study area, but it is unclear whether this decline is caused by selection towards smaller bodies or a stunting effect by poorer nutrition. Rising stature around what is today the Channel, as well as the southern Baltic Sea area F, G well fit such an explanation, as rapid land loss during the early Holocene increased access to marine resources Gaffney et al.
This is not surprising given the broad spectrum of exploitable food resources Scheibner and the gradual development from foraging of wild local species to tending and domestication Zohary et al.
The diverging long bone length trends may point to a more complex population history than the current idea of the Fertile Crescent as core region of origin for outward dispersals suggests and puts a general caveat to stature estimates in this region, as a decline in stature is only visible after ca.
This pushes the onset of the long-suspected negative effects on health and stature by way of nutrition and disease load brought about by a sedentary lifestyle formerly associated with the primary Neolithization in the Near East e. It entailed not only the introduction of completely new foodstuffs such as cereals and pulses as well as milk products Craig et al.
Nevertheless, no reflection in stature during and after the Pre- and Protosesklo cultures ca. Likewise, further sea-bound Neolithization across the Mediterranean into the Adriatic and Western Mediterranean instigated by the Impresso-related cultures ca.
This supports that at least in coastal areas Neolithization did not lead to substantial changes in the nutritional composition of the diet for isotopic evidence in the Aegean see Rosenstock and Scheibner In the Balkans, previous studies have focused on the skeletal material from the Iron Gates region as virtually the only anthropological source for the Mesolithic in the region.
As the effect of this data is moderated in the models presented here, it appears questionable if the negative impact of Secondary Neolithization in Southeastern Europe on stature at ca. Rather, some stature decrease already starts around ca. Moreover, a dietary shift towards lower trophic levels is observable in the isotopic record of the region at the transition of the 7th and the 6th millennia Rosenstock and Scheibner Hence, the subtleness of impact on stature in Southeastern Europe is remarkable.
This contradicts previous studies e. However, their findings may largely be the result of comparing mainly western Mesolithic skeletons with mainly eastern Neolithic skeletons, an effect which is alleviated in our models. After the 4th millennium, a general trend of increasing stature is observable in almost the entire study area Lalueza-Fox ; Bennike ; Jaeger et al. Angel and the Balkans MacIntosh et al.
Especially in the light of evidence for negative impacts of urbanization on biological welfare in historical periods due to the easier spread of infectious disease in densely populated communities e.
It must be kept in mind that the development of more stratified societies might have led to a bias towards taller individuals in the skeletal database due to social screening effects favoring taller people Teschler-Nicola Increased spatial mobility is likely to have resulted in increasingly mixed gene pools in the populations of the Old World.
In such populations, heterosis effects, i. Moreover, increased social mobility as a by-effect of social stratification is thought to be associated with stature increase due to the so-called community effect that views stature as a biologically expressed signal on social status Bogin et al. It encompassed new foods, i. Dairying probably intensified Greenfield based on ideas by Sherratt , and wine, olive, and other arboriculture developed Myles et al.
The resulting better nutrient supply and lower workload might also have generally increased stature in the Copper and Bronze Ages Rosenstock et al.
This general trend to increasing stature in later prehistory is superseded by a simultaneous even stronger increase in stature in Northern Europe noted earlier Bennike ; Roberts and Cox ; Niskanen et al.
After another threshold-like arrest of the Neolithic in Central Europe, the Funnel Beaker culture represents the first Neolithic farmers in Northern Europe after ca. Additionally, the subsequent Corded Ware culture is closely related to the Yamnaya culture of the Pontic Steppes according to archaeological Kaiser and archaeogenetic Haak et al.
The lack of any signal for the immigration of smaller stature from Iberia into Western and Central Europe sheds significant doubt onto the commonly held view that the Bell Beaker culture originated in the Iberian Peninsula. Rather, it is well in line with a Corded Ware-based origin in NW Europe advocated earlier for archaeological van der Waals ; Jeunesse and most recently for archaeogenetic reasons Olalde et al.
Moreover, given the somatotrophic and probably growth hormone—related effect of unfermented milk Wiley or an assumed direct relationship between genes determining tall stature and lactase persistence Grasgruber et al.
This assumes that the current prevalence of this genetically determined trait, for which first evidence is found in the Bell Beaker culture of Central Europe Mathieson et al. Consequently, the 4th to 3rd millennia have come into focus, either by postulating Northern European cultures as a possible origin of the trait Grasgruber et al. This confirms that Bayesian error-in-variables modeling of stature estimated using the Pearson , Ruff et al.
One of its advantages is that it not only allows for the inclusion of larger cemeteries but can also bring data on single individuals to meaningful use. In weighing all available data according to temporal and spatial distance, it counteracts over-interpretation of larger datasets on otherwise ill-attested times and regions and allows for more dating precision than previous studies.
Overall, the modeling method appears to smoothen regional and temporal variance to a degree that only robust trends become manifest, making them a rather conservative approximation to the underlying facts. Long-term post-glacial and environmentally driven selection for taller stature in Eurasia and shorter stature in Iberia predicted by archaeogenetics is confirmed by the actual phenotypic data.
Moreover, regional stature trends might also reflect regional subsistence differences within the Broad Spectrum adaption. Here, especially previous notions about declining stature during the Primary Neolithization in the Near East have to be re-visited. Discrepancies between the long bone models presented here, however, underline the fact that the Near East is still an under-researched region in terms of both morphology and genetics of prehistoric populations.
While secondary Neolithization by means of migration and acculturation might have led to some stature decline in the Balkans with the advent of the Neolithic at ca. This calls for revision of studies that identified a clearly negative impact usually based on very divergent Mesolithic vs. Neolithic datasets with an insufficient temporal resolution and rethinking of archaeological ideas about Secondary and Tertiary Neolithization as processes rather than a point in time.
From the 4th millennium onwards, increasing heights are visible in almost the entire study area. However, also other factors such as the Tertiary Neolithization of Northern Europe characterized by changing modes of production during the 4th millennium or the onset of the consumption of unfermented milk beyond childhood not earlier than the 3rd millennium cal BC must be considered.
In any case, the stature increase in Later Prehistory was marked enough to establish the Northwest-Southeast gradient in European and Near Eastern stature that can be traced through Antiquity and the Medieval and Modern Period until today.

For the new study, Grasgruber and his team surveyed male students aged 17 to 20 years old from Bosnia and Herzegovina. Each participant filled out a basic questionnaire and had their height, sitting height, and arm span measured.
The research is part of a larger ongoing survey of both men and women from countries known to have many tall individuals. As Grasgruber previously indicated, good nutrition and environmental factors can influence the height of a population.
Agriculture was introduced during this time, which led to more permanent settlements in villages. Finally, during the Neolithic period roughly 8, B.
They domesticated animals and cultivated cereal grains. They used polished hand axes, adzes for ploughing and tilling the land and started to settle in the plains.
Advancements were made not only in tools but also in farming, home construction and art, including pottery, sewing and weaving. During the Bronze Age about 3, B. Now used for weapons and tools, the harder metal replaced its stone predecessors, and helped spark innovations including the ox-drawn plow and the wheel. Home dwellings morphed to so-called roundhouses, consisting of a circular stone wall with a thatched or turf roof, complete with a fireplace or hearth, and more villages and cities began to form.
Organized government, law and warfare, as well as beginnings of religion, also came into play during the Bronze Age, perhaps most notably relating to the ancient Egyptians who built the pyramids during this time.
The earliest written accounts, including Egyptian hieroglyphs and petroglyphs rock engravings , are also dated to this era. The discovery of ways to heat and forge iron kicked off the Iron Age roughly 1, B. At the time, the metal was seen as more precious than gold, and wrought iron which would be replaced by steel with the advent of smelting iron was easier to manufacture than bronze. Along with mass production of steel tools and weapons, the age saw even further advances in architecture, with four-room homes, some complete with stables for animals, joining more rudimentary hill forts, as well as royal palaces, temples and other religious structures.
