This is exceptionally improbable, in light of the fact that there are no primates that sleep. Furthermore, our species began in warm atmospheres. At the point when our precursors moved to colder areas, they experienced some hereditary changes, the most remarkable one being fair skin to take into account more UV ingestion abd sufficient vitamin D blend, and likely when they (and the Neanderthals too) achieved the Northern scopes, they as of now were effective apparatus clients and talented seekers and they made garments. They would have had no motivation to experience a gigantic transformative change in such a significant number of frameworks, to advance the ability to sleep sans preparation. Not to mention lose it a short time later.
