Eggs by rail

The common sense, sturdy construction of this wooden egg crate and thousands like it ensured that once the eggs had been wrapped with a layer of crepe paper, they were good for journeys across Europe. France, Holland and Denmark all exported eggs to England in the latter half of the 19th century and on into the 20th.

Fighting over food

The truth is unlikely ever to emerge from the rubble of world war two, but the British ruling class was convinced that there was a significant black market trading in the wartime British Isles. The obsession with even the possibility that spivs might be getting away with crimes against upstanding citizens is captured by William Sitwell in his book Eggs Or Anarchy.

At this time, the House of Lords could be relied upon to make the most fuss over the least incident supported by little or no evidence. The sensitivity of the establishment to the idea that people might be getting away with crime, be it real or imagined, beggars belief. One particularly paranoid peer accused Lord Woolton, then minister of food, of failing to act in a timely manner to pre-empt the spread of profiteering, which he now believed to be out of control.

Woolton was, of course, held responsible for this state of affairs, be it real or imaginary. A man of humble origins, his arrival in the upper house was a reflection on his achievements in business rather than his birthright. To be sure, he was as irked by tales of black marketeering as his fellow peers, yet he was to be judged on getting results that were far from being attainable.

Fire power

In his book Against The Grain, James C Scott discusses the use of fire as a tool to manage the environment. Through clearing rain forest with fire, prehistoric hominids discovered that the burnt areas recovered rapidly, becoming more attractive to the species that were hunted for food. Attracted by tender green shoots and lush grass, grazing herbivores were followed by their carnivorous predators, much to the satisfaction of the hunter gatherers.

By creating productive oases of harvestable food, the hominids no longer needed to travel so far to find food. The pressing need to move on and start looking for fresh sources of food started to lose its urgency. But Scott has a more intriguing discovery to relate.

The closest relative to hominids is the chimpanzee, which has a significant difference, despite sharing almost all its genetic traits with humans. The chimp’s digestive system is elaborate and robust, allowing it to digest cellulose and tough vegetation. This heavy duty digestive function is absent in homo sapiens, Scott argues, because the use of fire for cooking food makes it easier to digest. It is as though homo sapiens has externalised the digestive functions by cooking on fires.

Having made the transition to a lighter, swifter digestive system, humanity is not going to reverse the process any time soon. Humanity is committed to maintaining a pattern of routine burning in the rain forest, just to carry on eating. We are now dependent on the restraints that we took on willingly millennia previously and are irrevocably committed to cooking and eating food, ranging over shorter distances than before. The domestication that came with fire changed humanity’s future development.
