Palaeoanthropology and the Evolutionary Place of Humans in Nature
Bibliographic record
Abstract
Palaeoanthropology, the study of the fossil evidence for human evolution, remains a highly contested field. New discoveries are continuously being used to promote alternative models as well as to propose new candidates for our ultimate ancestor. The fossil evidence has increased over the years, and has been supplemented (and often challenged) by molecular data drawn from living people and the great apes. As recently as the 1980s, palaeoanthropologists proposed that human roots stretched back into the Middle Miocene, between 17 and 8 million years ago. Then the earliest true hominids or human ancestors became the South African australopithecines, who are less than 5 million years old. Now there appears to be a tremendous variety of early humans at all stages of their evolution. Along with this new research on the basal hominids has been a renewed interest about what it means to be Homo sapiens . Molecular and fossil data shows that Africa was also our homeland, and that all people today are descended from a small founder population in existence there between 50,000 and 200,000 years ago.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
