Scientists report genetic traces suggesting two unknown human relatives

Multiple reports state that researchers have identified genetic traces that may point to two previously unknown human relatives. The articles describe the findings as “hidden” within human DNA, implying that past interbreeding or shared ancestry left detectable signals. According to the coverage, the signals are described as remnants of two distinct lineages, often referred to as “mysterious” or “ghost” relatives because they are not identified as known, well-characterized hominin groups in the public record. The reporting emphasizes that the evidence comes from genetic data rather than newly discovered fossils, and that the traces are subtle. While the articles do not provide detailed methodology or figures in the supplied text, they consistently frame the work as an attempt to infer additional ancestral contributors using modern genomic information. Overall, the sources agree that the study presents genetic indications of two additional human-related populations and that these findings expand the picture of human evolutionary history beyond currently documented relatives.
