We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Birth — The entry states that bird eggs contain a developing embryo at the time of laying, but in reality, the embryo is typically at an early stage (zygote or early-stage embryo) and develops significantly only after incubation begins.
Pouch (marsupial) — The extinct thylacine did not have a rudimentary, non-functional pouch-like fold in males; male thylacines had a scrotum, not a pouch.
Pouch (marsupial) — The male numbat does not have a rudimentary pouch; male numbats lack a pouch entirely.
Preterm birth — The claim that the white preterm birth rate is 9–10% is inaccurate; the commonly cited rate is about 9.1%, not up to 10%.
Preterm birth — The claim that 0.5% of births are extremely early periviable births at 20–25 weeks is inaccurate; the 0.5% figure typically refers to births before 28 weeks (20–27 weeks), not the 20–25 week range.
