[1] The name Karasuk was proposed by George van Driem of the University of Leiden.

[3] Václav Blažek (2019) places the linguistic homeland of Proto-Yeniseian close to where Burushaski is now spoken today in Pakistan.

He argues that based on hydronomic evidence, Yeniseian languages were originally spoken on the northern slopes of the Tianshan and Pamir mountains before dispersing downstream via the Irtysh River.

However, neither the Burushaski nor the Yeniseian verbal morphology has been rigorously analysed,[5] and reviewers have found the evidence to be weak.
