In 2005, Sax was featured in a National Geographic documentary about the lake. It is not a weapon injury, the researchers noted, but came from a blow from a blunt and round heavy object. This stretch of the Himalayas is notorious for hailstorms, which destroy crops and damage property. [20], Frederik Kortlandt postulates a shared common ancestor of Indo-European and Uralic, Proto-Indo-Uralic, as a possible pre-PIE. Using a mathematical analysis borrowed from evolutionary biology, but basing their work on comparative vocabulary, a number of researchers have attempted to estimate the dates of the splitting up of the various Indo-European languages. It is likely that the newcomers perpetrated a large-scale killing of local men, boys, and possibly male infants. [173] While Anthony (2007) situates the development of pre-Germanic dialects east of the Carpathians, arguing for a migration up the Dniestr,[174] Anthony (2017) relates the origins of the Corded Ware to the early third century Yamna-migrations into the Danube-valley, stating that "[t]he migration stream that created these intrusive cemeteries now can be seen to have continued from eastern Hungary across the Carpathians into southern Poland, where the earliest material traits of the Corded ware horizon appeared. Although some have proposed a common ancestor (the hypothetical Nostratic macrofamily), this is generally regarded as the result of intensive borrowing, which suggests that their homelands were located near each other. Language links are at the top of the page across from the title. The Dutch scholar Marcus Zuerius van Boxhorn (16121653) noted similarities between various European languages, Sanskrit, and Persian. Genetic science was vital in discrediting racist biological theories and establishing that racial categories are ever-shifting social constructs that do not align with genetic variation. The research on the Indo-Aryan migrations began with the study of the Rig Veda in the mid-19th century by Max Muller, and gradually evolved from a theory of a large scale invasion of a racially and technologically superior people to being a slow diffusion of small numbers of nomadic people that had a disproportionate societal impact on a large urban population.
