Christmas Spirit

World War One, also called The Great War, is notorious for the horrors endured by soldiers and civilians during the four-year period. One of the horrors was trench warfare – a new type of battle where two armies would dig into trenches stand-off across a No Man’s Land. It was a particularly terrible experience due to constant PTSD-inducing artillery barrages, extremely unsanitary living conditions and the looming shadow of death that clouded the skies.

But even within these terrible times, the light of humanity shone through. In December 1914, the German army was facing off the French and British army along the Western Front. In the week leading up to Christmas, there were increasing reports of strange behaviour among troops from both sides: fraternisation.

It began with music and light. Many British soldiers reported seeing bright coloured lights from the German lines on Christmas Eve. They heard choruses of Germans singing carols, with not a gunshot to hear. The British and French forces joined in quickly and suddenly, the soldiers were all enjoying Christmas Eve. They were in an informal ceasefire.

Little by little, the two sides made contact on Christmas Day. Not with shots, but with greetings. They would compliment each other’s singing and make jokes across the ditch. Then, some fearless soldiers would cross No Man’s Land to meet their new friends face-to-face. It took a bit of time, but trust developed and soldiers would pop out of their holes without fear of being killed. The language barrier could not stop the fraternisation. Soldiers would make gestures at each other, exchange gifts such as smokes and chocolates and even challenged each other to a football match.
On Christmas Day, 1914, man’s love for each other won over the horrors of war, bringing the first period of peace since the Great War began. It was a Christmas miracle.

Of course, fraternisation with the enemy is far from desirable to a military commander. What man would want to shoot someone they just had a great game of soccer with? Killing only becomes possible when the victim has been dehumanised. This was the last Christmas Truce of the war, as commanders of both sides outlawed any fraternisation with the enemy.

Despite this, there are countless stories from the war where soldiers would show mercy to their enemies, reminding us how even during the darkest times of history, kindness and love exist.

Intelligent Life

One of the great questions in science is “could intelligent life develop on planets other than Earth?”. Even the general populace has heard of programmes such as SETI (Search for Extraterrestrial Intelligent Life) and mathematical models such as the Drake equation that attempt to predict the possibility of extraterrestrial intelligent civilisations. But an equally intriguing question we seem to neglect is: “could intelligent life develop on Earth?”.

The definition of “intelligent life” is hugely varying, but nonetheless attempts have been made to compare our intelligence level to other animals. From the pool of research throughout the decades, the most “intelligent” non-human animals appear to be chimpanzees, bonobos, great apes, dolphins, elephants, certain parrots, ravens and rats. There is much research on the intelligence of cephalopods (e.g. the octopus) that has shown promise. If we were to shift the focus from individual intelligence, we could also consider “civilised” animals such as ants, as they are capable of building vast cities with intricate societies. All of this shows that intelligence is not exclusive to our species. We have simply walked down the path of evolution where the trait of ever-increasing intelligence, knowledge and wisdom have allowed us to adapt to and survive our environment. Ergo, it is fair to consider the possibility that other animals are walking a similar path that may lead to the making of a species with intelligence comparable to us.

However, this only raises the theoretical possibility of intelligent life. What is the realistic, practical possibility of intelligent life developing on Earth in the near future? Put another way, could intelligent life develop in the presence of a higher intelligent life (e.g. humans)? The road that brought us to throne of “the most intelligent species on Earth” was not an easy one. We are but one of many other hominid (human-like) species that evolution produced while tinkering with the concept. For example, there was a time when we (Homo sapiens) shared the Earth with other intelligent hominids such as the Neanderthals. The Neanderthals are commonly pictured as simple, knuckle-dragging apes but in reality they were just as intelligent as Homo sapiens during that time. They had a culture similar to our own, developed stone tools just as complex and even made cave paintings in a display of art. The reason why we are not breaking bad with Neanderthal neighbours now is that (according to one theory) we successfully outcompeted them, driving them to extinction (there is debate whether genocide and cannibalism was involved).

Evolutionarily speaking, it makes sense for an intelligent species to wipe out another species trying to compete with the ecological niche of intelligence. This has been discussed in many works of science fiction, such as Planet of the Apes where the emergence of intelligent apes leads to the destruction of human civilisation. Arthur C. Clarke discussed this as a side plot in his novel The Songs of Distant Earth. Upon discovering a species of sea scorpions that show signs of intelligence such as social hierarchy and metal collecting, the scientists suggest that they should allow it to develop, but ultimately the government decides to eradicate them as soon as they attempt to migrate to land.

Suffice to say, given our track record in history involving the countless times colonists wiped out other civilisations to serve their purpose, there is a good chance that any new intelligent life would immediately be removed by us if they had the misfortune of arising during our time.

Four Fs

Biologists state that the driving force behind evolution can simply be summarised as four forces: fight, flight, feed and mate (“fuck”). These are known as the Four Fs. Evolution is described as the process by which species adapt to an environment through modifications in the genomes of successive generations. The Four Fs describe the adaptations most commonly seen in evolution; that is, the four things that species evolve in order to better adapt and survive their environment. For example, carnivores developed sharp teeth and claws to hunt better and herbivores developed faster legs to flee from their predators better. Nature is a vicious battleground where different species compete with each other for survival, and the Four Fs are the most powerful weapons of survival.

As much as we’d like to think that we are higher-order, civilised beings, human beings are still driven by the basic four forces that drive every other species in the world. Obviously, our bodies are well-adapted to these forces, such as our fight-or-flight drive activating in the face of danger to let us fight harder or run faster through adrenaline. Anyone can see that nature has done her job well by bestowing us the gift of satiety and orgasm to promote our feeding and mating. But what is interesting that the Four Fs go beyond our “natural evolution” to affect the evolution of our civilisation.

Consider this: what is the purpose of war? Since the dawn of time, mankind has spent a considerable amount of resources figuring how to most efficiently kill another group of people, or live in fear that other people will kill us. If we study the behaviour of chimpanzees (one of the few species other than us that wage warfare), we can see that their motivation is for food and sex (i.e. mating partners). This also applies to mankind and it is not a story of ancient times. It is well-known that raping and pillaging runs rampant during wars. Less than 800 years ago, a man named Genghis Khan was so successful in waging war that DNA evidence suggests that 0.5% of the world population are descended from him. Even in the present, countries wage war to secure natural resources to ensure that their people can eat, as the health of the economy directly correlates with the ability of people to put food on their plates. Almost every war essentially boils down to a fight for food.

Then what about sex? Like it or not, sex has been a tremendously influential force in history. From Cleopatra’s seduction of Caesar preventing Rome’s invasion of Egypt, to Henry VIII turning against the Catholic Church to marry Anne Boleyn, sex has been a timeless motivator for humanity. Although the consequences would not be as dramatic as those described, a significant proportion of our actions are also based on our primal desire to reproduce.

Of course, this is not always the truth and human beings are capable of acting on less wild motivators such as happiness and altruism. However, the next time you make a decision or see a conflict on the news, question this: how much of an impact did food and sex have to motivate that?

Metal

Next to the discovery of fire and the wheel, the discovery of metals and the mastery of metalworking was arguably one of the most important advances for prehistoric humanity. Metal was far superior to rock, clay, wood or any other natural resource known to man in terms of strength and sharpness. Because of these properties, metal soon became a valuable commodity. It can be seen how much impact metal had on humanity’s history, considering that the stages of human prehistory were named after the type of metal (or lack thereof) that was mastered then: Stone Age, Bronze Age and Iron Age.

The discovery of metal came in two ways.

One was through mining, where prehistoric people discovered that shiny, hard objects were buried in the ground. They later discovered that with enough heat, they could melt the metal out of ores (copper and tin were the first metals to be gathered this way) and mould them into any shape. After smelting technologies developed, our ancestors found that mixing copper and tin produced bronze – a much stiffer and more durable metal than either of its components. A mixture of metals is called an alloy. This was the start of the Bronze Age. Bronze was extremely useful and people quickly came up with innovative ways of using it, such as farming equipment and weapons.

Some other metals used during this age were: gold, silver, lead and mercury. It is likely that gold was one of the earliest metals used as it comes in pure nuggets and is easily workable thanks to its chemistry. However, given that gold is rather soft and was treated more as jewellery than a practical metal, it was not used as much to advance technology.

The second way mankind came upon metals was in the form of “gifts from the gods”. A prime example is iron. Although the Iron Age began around 1200BC at the earliest, there are iron objects (mainly jewelleries) that have been dated back to 5000BC. How could this be? This was before mankind had the technology to smelt iron ores (which is more difficult and needs much higher temperatures than copper or tin ores), so the iron could not have been gathered through mining. The answer to this conundrum lies in meteorites. About 6% of meteorites contain iron and nickel, which prehistoric civilisations may have stumbled onto and taken the shiny pieces back to their tribe. The people would have considered the gathered iron a “gift from the gods”, as it had crashed down from the “heavens”. Because of this reason, iron was considered more valuable than gold or silver and was frequently used for jewellery. This is reflected in Arthur C. Clarke’s science fiction short story, The Songs of Distant Earth, where sentient sea scorpions hoard metal objects stolen from the humans and wear it proudly as a badge of honour.

The history of iron and how it was believed to be a gift from the heavens relates to a common superstition of how finding a penny (or any coin) represents good luck. As “metal” (mainly iron) was considered a holy gift bestowed unto mankind, finding a piece of metal was believed to be a blessing and some form of protection against evil. This is also represented in various traditions such as hanging horseshoes over doorways and wearing charm bracelets with metal on it.

Although it sounds like a silly superstition, it clearly shows how metals have been an integral part of the development of civilisation.

History Of The Earth

The Earth has been around for a good 4.6 billion years. Let us compress the long time from the Earth’s birth to today (2012) into one year to put everything in perspective.

The Earth’s history starts on January 1, 00:00:00. The Earth is a hard sphere, barren as any other planet. Incessant wind and rain erode away the barren mountains and tectonic forces create new ones. Nothing much happens for the next three months. Then, around the start of April, life begins in the form of bacteria. Over the course of the next few months, the bacteria divide and mutate, slowly forming new life forms that are multicellular. However, all life on Earth are still in the oceans.

Life on land only starts in the end of November, when plants begin to settle on land. Plants expertly take the abundant carbon dioxide in the atmosphere and convert it into oxygen. By early December, the oceans are teeming with fish, some of which adapt to living on land by developing lungs. These become the first amphibians. Insects also populate the land and become one of the most diverse types of life.

In December 12, reptiles evolve and the land is ruled by dinosaurs, but only for 9 days until they are wiped off the face of the Earth by a meteorite on December 20. Mammals quickly take the niche left by dinosaurs, populating the entire world. Even at this late time, there are no signs of humans.

December 31, humans have still not arrived on Earth. They only appear around 8pm, where the first hominids venture on to the plains of Africa. At 10pm, the Ice Age begins and the Earth is covered by a thick white sheet of ice. The ice comes and goes three more times. At 11:59pm, human civilisation begins as cities begin to rise. 22 seconds before the end of the year, the Egyptians build their pyramids. More monuments arise within seconds. At 11:59:47pm, Jesus teaches the people to love one another, until he is killed a millisecond later. In the last second of the year (about 150 years), humanity: has two major world wars, take to the skies, create the nuclear bomb that can wipe out all life on Earth and even step foot on the Moon.

We may like to think that we have made a significant impact in the history of the Earth, but we have only existed for an infinitesimally small fraction of the history. We are but a dot on the grand scheme of natural history.

Slavemaker Ant

Slavery is considered one of the most inhumane acts in humanity’s history, where a group of people enslave another group of people to do their bidding in harsh conditions. Slavery is an interesting concept as at the cost of other members of your species, you can greatly increase the productivity of your own society. Some may argue that only humans are evil enough to enslave their own kind, but there is one other species that enslaves other animals: ants.

Certain species of ants, known as slavemaker ants, are known to enslave entire ant colonies to do the bidding of their own colony. The way slavemaker ants enslave colonies is as follows. First, a pregnant queen ant lies in front of an enemy nest after mating and feigns death. Scouts from the nest carry the “body” back to their queen so that she may devour the fallen enemy. When the two queens are left in the same room, the queen slavemaker ant springs back to life and proceeds to eviscerate the other queen ant. She then rolls around in her remains to coat herself in pheromones – the substance through which ants identify each other. The ants of the colony now believe the queen to be their own queen and serve her and her eggs. When the brood fully matures (only soldier ants), they swiftly overrun the nest and completely enslave the colony, forcing them to fill the role of the worker ants, which the slavemaker ants lack.

Eventually, the original slaves die out and the colony becomes short on worker ants (as the queen only produces soldier ants). To overcome this issue, the colony sends out massive raiding parties to attack other colonies, after which the ants steal the eggs and larvae of the captured colony to breed them into new slaves. Interestingly, it has been observed that slavemaker ants tend to attack the most defended nests, knowing that they contain the most eggs and larvae. There are variations on how the army attacks and raids a colony depending on the species. Some choose to launch a full-on assault, decimating the colony and leaving only the eggs and larvae. Some secrete chemical gases that force the colony to evacuate, leaving their young behind in the rush. In some cases, a fertilised queen ant will sneak into a raid and kill the queen ant in the midst of the battle, commandeering whatever is left of the colony following the raid.

One difference between human and ant slavery is that slave ants are not aware they are slaves. Since they have been brought up since birth to work for the colony, they simply believe that they are worker ants birthed by the queen. Thus, they have no objections to serving the colony as to them they are merely fulfiling their objectives. 

This type of interaction between species is known as social parasitism, where one group benefits and survives at the cost of another group. Interestingly, “parasitism” also suggests that slavemaker ants cannot survive without their host. The reason being, slavemaker ants are so specialised in infiltrating and raiding other colonies that they cannot feed themselves or construct a colony by themselves. Even their mandibles are evolved into perfect killing machines, so much that they cannot use it to feed (slave ants have to feed them). In some cases, it has even been observed that slave ants had to carry their masters from one colony to another.

Slavemaker ants enslave not because they are tough or superior, but because they are desperate and have adapted to this unique form of surviving. Thus, if there was an Abraham Lincoln ant, he would certainly kill his colony within one generation.
