Left: average of known decay properties assigned to 288Mc and its daughters. Right: details of decay chains detected at the FIONA focal plane. Unobserved decays within each decay chain are indicated as ‘unobserved’ and are assumed to have been emitted out of the open end of the detector array. The x position of decays observed in the focal-plane detector is also given. Image credit: Gates et al, doi: 10.1103/PhysRevLett.121.222501.

Neanderthals are commonly thought to have relied on dangerous close range hunting techniques, using non-projectile weapons like the thrusting spears depicted here; this hunting approach is thought to have brought them into violent contact with large mammals, resulting in high levels of injury especially to the head and neck when compared to modern humans; Beier et al found similar head injury levels in both Neanderthals and Upper Paleolithic humans, casting doubt on this hypothesis.
