The above is a useful overview of what we know about the first invention of fire by early humans and its effects on mankind’s evolution. The earliest definitive use for fire use is around a million and a half years old, but phylogenetic analysis puts the invention of fire further back to around two million years ago, this is corroborated by the anatomical characteristics of species like Homo erectus, with reduced jaws and teeth that in some cases were the size of the teeth of modern people, as well as more reduced musculature compared to the non-human great apes and a far bigger brain in relation to body size than australopithecines, our ancestors, and great apes, with cranial capacity reaching up to 1100 cm.
The earliest evidence for habitual fire use dates to around 500,000 years ago, and we have indirect evidence that we were making glue from around this time too, see the article for more details on that. There’s some evidence both Neanderthals and early modern humans practiced fire stick farming from at least 120,000 years ago, and there’s evidence of leather working from around this time, for those who don’t know leather requires fire to make, and there’s also evidence for hand drills from around 400,000 years ago as well, instead of simply using the friction from rubbing two sticks together in an hearth on top of some kindling to ignite a fire, which is presumably the first method we devised for actually making fire.
We likely had the ability to control fire before we invented methods to ignite it, this would require knowledge of slow-burning materials to maintain fires for long periods of time, animal dung does the trick.
The paper here reports forensic findings on the death of an early European modern human some 33,000 years ago. What’s intriguing is that the death appears to have been intentional, inflicted by a club or a bat of all things. Furthermore, the evidence suggests it was perpetrated by a left-handed individual who was in a *face-to-face* confrontation with the victim.
This wasn’t sacrifice or an execution, this was a *murder*, committed by someone who had deliberately *confronted* the victim, it’s not unlikely that there would’ve been a heated argument, whoever murdered this man was *pissed*, and obviously knew him well.
The stories bones can tell us….
Abstract: Complex projectiles—propulsion via mechanical aid—are considered an important technological innovation, with possible relevance for the successful Out-of-Africa dispersal of our species. Conclusive evidence for the beginning of this technology, however, is lacking from the early Late Pleistocene (ca. 130 to 70 thousand years ago; ka). Given the extremely limited applicability of relatively robust methods for validating stone-tipped projectile use, such as through fracture propagation velocity, converging lines of circumstantial evidence remain the best way to examine early complex projectiles. We assess here suggestions for an early Late Pleistocene origin of complex projectiles in Africa. Results from both previous and present independent approaches suggest a trajectory in which complex projectiles were likely adopted during the early Late Pleistocene in eastern Africa. At Aduma (Middle Awash, Ethiopia), morphometric, hafting, and impact damage patterns in several lithic point assemblages suggest a shift from simple spear technologies (thrusting and/or hand-cast) to complex projectiles. Broadly dated to 80–100 ka, lithic points from later phases of the Aduma succession represent a particularly strong candidate for projectile armatures most comparable to ethnographically known spearthrower darts, lending support for previous suggestions and warranting further investigations.
Notes: This is interesting, very interesting, because it pushes back the date of the invention of the atlatl back to the Middle Paleolithic, long before modern humans spread out of Africa, and also long before the earliest evidence for the atlatl in the archaeological record, which AFAIK is from Aurignacian Europe, it’s also telling because Native Americans lacked the atlatl until the advent of the Archaic period, so either the ancestors of the Native Americans lost the atlatl sometime prior to the peopling of the Americas or the atlatl wasn’t as common as previously believed. The Tasmanians also lacked the spearthrower or atlatl, despite ultimately coming from the same population that left Africa as the rest of us did, while the Australians *did* possess the spearthrower, called the *woomera* there, although it was of recent (Holocene) derivation.
Very interesting, and this species demonstrates many similarities to Homo floresiensis, including sharing many basal traits with australopithecines and early members of the genus Homo. One wonders how it got there given even at the time Homo luzoniensis lived Luzon was still separated from the Asian mainland by miles of ocean.
The fact that *two* species of primitive human were found in the region at the same time suggests human evolution in the region was far more complicated than previously thought, but this is in line with the discovery of stone tools in China dating back to over two million years old.
