Human biological variation does not support subspecies or racial taxonomies
the verdict
SUPPORTED
the evidence backs this
confidence 87/100
Extensive genetic, anthropological, and genomic evidence demonstrates that human biological variation is continuous and clinal rather than divided into discrete subspecies or racial categories.
