Article Synopsis
  • - Horses transformed human mobility, but the timeline of their domestication and integration as transport is debated, with new genetic data being used to clarify this history.
  • - Analysis of 475 ancient horse genomes indicates that modern domestic horses were shaped by human intervention around 2200 BCE, after a domestication bottleneck began around 2700 BCE, leading to a significant expansion across Eurasia.
  • - Evidence also suggests that there was early horse husbandry in central Asia at Botai around 3500 BCE, prior to the establishment of contemporary horse bloodlines, challenging the notion of large herds being linked to migrations around 3000 BCE.

Article Synopsis
  • The domestication of horses significantly changed mobility and warfare, but modern breeds do not trace back to the earliest domestic horses found in Central Asia around 3500 BC.
  • Research reestablishes the Western Eurasian steppes, particularly the lower Volga-Don area, as the origin of modern domestic horses, based on genetic analysis from 273 ancient horse genomes.
  • The study finds that the spread of modern domestic horses around 2000 BC coincided with the emergence of equestrian cultures, refuting the idea that horseback riding was linked to the expansion of Yamnaya pastoralists in Europe.

Article Synopsis
  • Horse domestication had a profound impact on warfare, travel, trade, and language spread.* -
  • The study analyzed DNA from 149 ancient horses, revealing two distinct extinct lineages from Iberia and Siberia that didn't significantly contribute to modern horses.* -
  • The Persian horse lineages gained traction after Islamic conquests, and modern breeding practices have dramatically affected genetic diversity in horses compared to earlier human management.*

A randomized, double-blind, placebo-controlled, parallel-group clinical study with an extra non-treatment group was performed to measure the effect of a single dose of standardized SHR-5 Rhodiola rosea extract on capacity for mental work against a background of fatigue and stress. An additional objective was to investigate a possible difference between two doses, one dose being chosen as the standard mean dose in accordance with well-established medicinal use as a psychostimulant/adaptogen, the other dose being 50% higher. Some physiological parameters, e.
