  "account": "Aoki et al. (2023) suggested that the significant contrast in microblade distribution across the Qinling-Huaihe line before the early Holocene may have been attributed to a higher prevalence of diseases in the southern region. This could have resulted in a lack of migration for northerners due to increased vulnerability towards pathogen-induced illnesses. The study explores the potential impact of vector-borne diseases, whose distribution is dependent on climate conditions, on migration between the northern and southern areas. The researchers extended the original wave equation approach to factor in climate variability, including scenarios of linear warming, cooling, and temperature oscillations. By utilizing published climate records for the Northern Hemisphere since the Upper Paleolithic, simulations were conducted to identify potential timeframes during which microblade distribution could have extended to the southern regions.",
  "summary": "Aoki et al. (2023) proposed that the sharp difference in microblade distribution between the north and south of the Qinling-Huaihe (H-Q) line before the early Holocene could have been due to a higher frequency of pathogens in the south. Greater susceptibility to pathogen-induced disease among northerners could have effectively prevented migration across the H-Q line. Here, we explore the…",
