Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Multiple recent genetic and paleoanthropological studies demonstrate that the human brain and its underlying genetic architecture have continued to undergo evolutionary changes into recent history.

The analysis

The retrieved papers provide robust genetic and anthropological evidence (e.g., within-species encephalization trends, recent emergence of cognitive-linked genetic variants, and ongoing positive selection signatures) supporting the claim that the human brain continues to evolve. No papers refute this claim.
