An international team of scientists has successfully sequenced genome data of three mammals including a human from skeletal remains discovered in Georgia's west, revealing "previously undocumented" ancestral lineages.

Unearthed from the Satsurblia Cave in the Tskaltubo Municipality between 2012-2017, the remains had been subjected to long studies that eventually yielded data using "shotgun" method of sequencing, giving the professionals information on Pleistocene-era sediments.

Among the key findings is a pre-Last Glacial Maximum lineage of humans - "an ancestral component of West Eurasia" - from around 25,000 years ago. The studies have also pointed to a wolf genome "basal to extant Eurasian wolves and dogs" and also previously unknown to scientists.
