From a “Molecular Ghost” to a Recognizable Ancestor: How Paleoproteomics Identified the Xujiayao Hominins as Denisovans

A Nature study (Oct 21, 2026) by Fu Qiaomei and Xing Song of IVPP and collaborators used paleoproteomics on powdered bone from the Xujiayao fossils to confirm the hominins were Denisovans, and for the first time established a morphological identification standard for this ancient lineage—suggesting Denisovans once ranged across nearly all of East Asia.

Know What Your Grandfather and Grandmother Each Passed to You—Without Testing Them? Inside Ancestry’s New Regions-by-Grandparent Feature

At its 30th-anniversary event, Ancestry unveiled its biggest DNA update yet: twice as many ancestral regions, plus a new 'Regions by Grandparent' feature that estimates which DNA regions you inherited from each of your four grandparents—no tests from parents or grandparents required. Here we explain how it works, what it means, and where its limits lie.

[Explainer] When 20 STRs Are Not Enough: Why Both Forensics and Ancient DNA Turn to 90,000 SNPs

~20 STRs suit parent–child testing but fail on degraded bone and cousins. Typing ~95,000 short-fragment SNPs fixes both — and forensics and ancient DNA both swear by the petrous bone.
