True
The text discusses the palmaris longus muscle, noting that about 15% of people lack it, it doesn't affect grip strength, evolution is erasing it, it was important for climbing, and surgeons use it in surgeries.
Infact verdict: True (85/100).
The claims about the palmaris longus muscle are generally supported by evidence. Approximately 15% of people lack this muscle, and its absence does not affect grip strength, as corroborated by multiple reliable sources. Evolutionary evidence suggests the muscle is becoming less common, and it was historically significant for climbing. Modern surgeons frequently use it in reconstructive surgeries. Overall, the claims are factual and well-supported by scientific literature.
