DNA is not identity

Biological kinship and population changes

DNA helps investigate kinship and population movements, but does not indicate what language a person spoke.

History and context

Broad samplings find founder effects compatible with population movements and regional contributions from forest groups, eastern herders and Khoe-San populations.

Shum Laka and the Swahili coast show local histories that defy simple replacement. Each graph retains sample, date, interval and proxy definition.

Evidence and interpretation

Data measured in specific sets. Caution: statistical ancestry does not equal language, identity, belonging or territorial rights.

Comparing the whole genome with an analytical selection

In the 2023 study, researchers repeated part of the analyses after excluding segments statistically attributed to regional admixture, retaining components related to west-central Africa. The geographic structure persisted, allowing investigation of additional processes, such as successive founder effects. Comparing both versions clarifies what question each graph answers: one describes the sampled genomes in full; another isolates a signal via an analytical procedure. That selection of segments is a tool of the model, not an operation to separate people more or less authentically belonging to a community.
