In terms of progress in DNA sequencing this is quite an old news. Quite a lot of studies have been conducted since then with better sequencing techniques. David Reich, a well known researcher in the field, a student of Svante Pääbo who was awarded the Nobel Prize[1] for pioneering this field and technique, has authored a terrific book[2] synthesising all these findings. The details are fascinating a nuanced, highly recommend this book if you would like to pursue this rabbit hole. The book from Svante Pääbo [3] is equally fascinating which goes into the details of how DNA sequencing works to determine ancient ancestry. In a way it takes off from where the Y-chromosome study ends.
