Shared DNA Segments
Segments of DNA you share with ancient individuals (identity-by-descent). Sharing indicates a population-level genetic connection, not a named common ancestor.
Southeast Asia and Oceania were linked by coastlines, islands, and some of humanity's greatest maritime migrations.

Reading shared segments
What a centimorgan (cM) measures
A centimorgan is a unit of genetic length. Longer and more numerous shared segments indicate a stronger genetic connection between your DNA and an ancient individual's DNA at the population level.
Why confidence varies
Ancient DNA is often incomplete. Confidence reflects how many markers could be compared with each individual. Low-confidence matches rest on fewer shared markers and should be read with more caution.
Why segment sizes matter
Across thousands of years, shared DNA is broken into many short pieces. Short segments are common between people from related populations; longer segments are rarer and more informative. Neither indicates a specific named ancestor.
