Reconstructing Anaximander's biological model unveils a theory of evolution akin to Darwin's, though centuries before the birth of science.

Anaximander's fragments on biology report a theory of evolution, which, unlike the development of other biological systems in the ancient Aegean, is naturalistic and is not based on metaphysics. According to Anaximander, evolution affected all living beings, including humans. The first biological systems formed in an aquatic environment, and were encased in a rugged and robust envelope. Evolution progressed with modifications that enabled the formation of more dynamic biological systems. For instance, after reaching land, the robust armors around aquatic beings dried up, and became brittle, This led to the loss of the armor and the development of more mobile life forms. Anaximander's theory combines observations of animals with speculations, and as such mirrors the more famous theory of evolution by Charles Darwin expressed 24 centuries later. The poor reception received by Anaximander's model in his time, illustrates a zeitgeist that would explain the contemporary lag phase in the development of biology and, as a result, medicine, in the ancient western world.

The biblical plague of the Philistines now has a name, tularemia.

An epidemic thought to have been the first instance of bubonic plague in the Mediterranean reveals to have been an episode of tularemia. The deadly epidemic took place in the aftermath of the removal of a wooden box from an isolated Hebrew sanctuary. Death, tumors, and rodents thereafter plagued Philistine country. Unlike earlier explanations proposed, tularemia caused by Francisella tularensis exhaustively explains the outbreak. Tularemia fits all the requirements indicated in the biblical text: it is carried by animals, is transmitted to humans, results in the development of ulceroglandular formations, often misdiagnosed for bubonic plague, and is fatal. Moreover, there is the evidence from the box and rodents: mice, which are known carrier for F. tularensis and can communicate it to humans, were credited by the very Philistines to be linked to the outbreak, and are small enough to nest in the box. Mice also explain the otherwise odd statement in the biblical text of a small Philistine idol repeatedly falling on the floor at night in the building where the Philistines had stored the box as mice exiting the box would easily have tipped over the statuette. Tularemia scores yet another point: an episode of the disease is known to have originated in Canaan and spread to Egypt around 1715 BC, indicating recurrence for the disease, and suggesting Canaan was a reservoir for F. tularensis in the 2nd millennium BC.

The 'Hittite plague', an epidemic of tularemia and the first record of biological warfare.

A long-lasting epidemic that plagued the Eastern Mediterranean in the 14th century BC was traced back to a focus in Canaan along the Arwad-Euphrates trading route. The symptoms, mode of infection, and geographical area, identified the agent as Francisella tularensis, which is also credited for outbreaks in Canaan around 1715 BC and 1075 BC. At first, the 14th century epidemic contaminated an area stretching from Cyprus to Iraq, and from Israel to Syria, sparing Egypt and Anatolia due to quarantine and political boundaries, respectively. Subsequently, wars spread the disease to central Anatolia, from where it was deliberately brought to Western Anatolia, in what constitutes the first known record of biological warfare. Finally, Aegean soldiers fighting in western Anatolia returned home to their islands, further spreading the epidemic.

Medical papyri describe the effects of the Santorini eruption on human health, and date the eruption to August 1603-March 1601 BC.

Egyptian medical papyri date the Santorini eruption, and reconcile the hitherto perceived dichotomy between archaeological/historical and scientific data. The medical documentation describes ailments, which can only have arisen from a volcanic source: ash fallout, rain acidified by ash, and a plume. Furthermore, the Egypt described by the medical texts matches the one in the series of so-called biblical plagues. This match in turn provides the length of time, 19 months, between the initial and final phases of the eruption, each phase contributing to the otherwise odd accumulation of sulfates spread over two consecutive biennia (1603-1600 BC) in Greenland's ice core. As a result, the initial phase of the eruption can be dated to August 21, 1603 BC, and the final one to March 1601 BC, in full agreement with the radiocarbon data (1627-1600 BC) based on the outermost ring on the branch of an olive tree killed by the eruption.

Six medical papyri describe the effects of Santorini's volcanic ash, and provide Egyptian parallels to the so-called biblical plagues.

Six medical papyri document how Santorini's volcanic ash from the Bronze Age biphasic eruption, otherwise attested by material retrieved at the bottom of lakes at the edge of the Nile Delta, severely affected the health of the inhabitants of Egypt as well as their society as a whole. Treatments for burns caused by particulate and dissolved acids are documented in the London Medical Papyrus as well as in the Ebers Papyrus, and are compatible with ash fallout and ash in rain, respectively. Furthermore, both instances of ash correlate to the first eight biblical plagues. Moreover, the latter text also presents a series of ailments coherent with serious inhalation of toxic substances in aerosol form. This scenario is confirmed by the Hearst Medical Papyrus, the Carlsberg Papyrus 8, and the Ramesseum Papyrus III, and fits a volcanic plume, which is also coherent with the ninth biblical plague of palpable obscurity as well as Santorini's second phase of its Bronze Age eruption. Finally, a sixth contemporary medical text, the Edwin Smith Surgical Papyrus, a manual to practice on wounded soldiers, supplies an insight into the collapse of the sociopolitical system of the time. The text appears to provide an insight into the sociopolitical climate in the aftermath of the Santorini eruption, possibly describing conditions that would have led to the tenth and final biblical plague of the massacre of firstborn as well as the escape of slaves from local labor camps.

Treatments for burns in the London Medical Papyrus show the first seven biblical plagues of Egypt are coherent with Santorini's volcanic fallout.

Six treatments for burns in the London Medical Papyrus provide data regarding a volcanic fallout over Egypt. They confirm a previously established scenario linking the medical text to one specific eruption, the one at Santorini in the Bronze Age. One treatment describes the contamination of waters with the ash. Four treatments describe the effects of the ash on the skin. The sixth treatment describes the effect of acid rain following the dispersion of ash in the atmosphere, which triggered weather anomalies. The scenario derived from the medical document, is based on ash from Santorini that sedimented at the bottom of Egyptian lakes, and fits the description of Egypt in the papyrus The Admonitions of an Egyptian Sage. Finally, the scenario explains the nature of first seven biblical plagues of Egypt in light of the aftermath of volcanic ash littering Egypt.

Ancient Egyptian doctors and the nature of the biblical plagues.

Paragraph 55 of the London Medical Papyrus describes burns derived from red waters and which later became infected with larvae in the wounds. The prescribed treatment for the burn is unusual as it calls for no rinsing and requires bandaging with alkaline materials only. Refraining from washing in the Nile (the single most readily available source of water in ancient Egypt), and the use of alkali-neutralizing agents indicates that the red caustic waters came from the river, and were acid in nature. A red, acid Nile is consistent with the first biblical plague of Egypt, which killed fish, and kept people from drinking from the river. In turn, the sulfate-laced waters of the medical document also offer a plausible insight into the subsequent biblical plagues. Amphibians would have stayed away from the deadly river, left to die on the banks, just as described in the second biblical plague. Similarly, the larvae in the wounds mentioned by the medical document re-echo the third and fourth biblical plagues: the kînnîm invertebrates and the subsequent 'arob (varied insects) are consistent with larvae and the subsequent adults thereof. In pre-industrial Ancient Egypt, sulfates from a massive volcanic fall out provide the simplest and most exhaustive origin for such waters. A massive precipitation that would account for the waters in the medical document and the biblical texts is known from sediments at the bottom of lakes along the Nile Delta. The site is downwind from the island of Santorini, and the deposit of volcanic ashes took place during the Middle Bronze Age, i.e. at a time consistent with the eruption at the Greek volcanic island.
