Ante Hominem

If you enjoyed any of the animated feature films centered on insect colonies made since 1998, you are in for surprises below. No matter how much they anthromorphised their characters, none of films came close. In fact, in the case of ants, even the word 'anthropomorhic' would seem to be backwards.

Earlier posts here have looked at the origins of agriculture in various contexts, and the implications of the competing theories. One thing the theories all have in common is the starting assumption, of course, that humans retain all the credit. All the archaeological and genetic evidence though has nothing on my theory (playful conjecture) that we could and may have picked it (and much more) up from ants.

The eusocial insects exhibit close models of any of the fundamental structural templates of human society, barring religion (a telling exception for another day). Ant colonies are organised around division of labour (or castes), agriculture, livestock herding, tribalism and even warfare, complete with suicide bombers, chemical weaponry and mercenary forces. What is more, they have been at it for far longer than us, about 5000 times longer. Hence the title. All of that takes communication that is so sophisticated that we are still unraveling its intricate mechanisms. But without scientifically understanding the intricacies, any curious Cro-Magnon human could have come across these ideas as he sat under a tree in deep thought, got distracted by and followed an industrious trail scurrying by.

An observer can readily infer division of labour – ants with different roles are all different sizes, often even different morphology and colour. Even if you naively assume the animals carrying all the food shipments are entirely different from those attacking usurpers, the organisational principle is clear inasmuch as they all cooperate towards deliberate common goals.

Agriculture too is plainly visible in some species – huge parades carrying pieces of leaf laminae into a tunnel where fungi are meticulously cultivated on them and harvested. All the coincidence you need is to pass by right after an animal has disturbed an ant hill. Or, you could be the animal that disturbs it. When you peer in, if they are not harvesting fungi, you might find them rearing scale insects to gather honeydew off their backs, which is uncannily analogous to us milking cattle.

Their ancient demonstration lessons are not limited to organisation of the collective. Ants also use tools. I do give us credit for enough intelligence to have stumbled across this one all on our own. That is why this one is not on the list above. After all, tool use is known among corvids, pachyderms, cetaceans and simians, all of whom are larger and easier to observe. We could have learnt it from any of them!

(As an aside, tools used to be on the hallowed list of things we proudly displayed laminated and framed on our walls - things that separate us from animals. Despite what you may have learnt at school, tool-use came off that list long ago, followed by the likes of empathy, fairness, laughter, self-awareness and memory. At that last one, the animal far exceeds what is expected of average humans. I do not add qualifiers such as ‘far’ lightly. Go ahead, check the link. I dare you to retain your pride intact.)

But ants are one up in tool-use too – wait until you hear what their tools include. Some species use their own young as machines of sorts! Weaver ants (Oecophylla smaragdina) use the silk from their larvae as the binding material for their elaborate woven nests. And they do not take just the silk to where it is needed. The picture above is the best licensed version I could find, but National Geographic has the money shot here. That is an ant that just brought a larva back from the nursery and is wielding it with pin-precision to extrude silk and fasten leaves together. Raise your hand if that does not shatter your own hermeneutic paradigm of natural ‘order’, whether based on the Aristotelian scala naturae or the Hindu-Buddhist conception of Saṃsāra.

Old School

Much of what we (25 and over) learned in school is now moot.

Makes me wonder how schools cope with the lag in updating textbooks in the Information Age. Even the most advanced teachers who largely dispense with texts in favour of videos and such cannot hope to keep up with students who follow science blogs. I imagine schools turning into battlegrounds – at least those that have teachers like mine who encouraged students to challenge them in class. And if you think I am exaggerating the issue, let us take stock of the magnitude of what has changed.

Religion may have led to settlement and necessitated agriculture, rather than the other way around. That is a big one. For all the militant atheism supposedly sweeping the world, it seems we might need a second look at religion after all. To understand who we are and where we come from, we examine how we progressed from a gloriously natural animal existence to the present. It is profoundly central question - what came first? Did the need to transcend our physical existence to seek a higher spirit give rise to the first fixed building or did the discovery of cultivating a food surplus finally allow us to settle down?

You might want to sit down for this next one. I often goes after E, never mind where C is. And this is not even a new finding. Turns out, there are – and have always been – far more words that flout that rule than otherwise! English teachers around the world - yes, including English English teachers - just never bothered to check. Many, I fear, still continue to refer to it while helping students to spell better. Imagine the shock they get when they leave school. Even Harry Potter was stumped, which is some consolation.

Life arose in the sea, we were told and always thought. It certainly added to the awe I felt during pre-dawn strolls along sea shores; apart from its sheer vast spread and unfathomable depths, it was also where we came from. Evidence since uncovered suggests that the first living cells may have emerged in geothermal pools on land. The open ocean just got a little less enigmatic.

Pluto used to be planet. There were nine. But this one I expect they must have corrected even in texts by now.

(Update: We have far more than five senses, including thermoception, proprioception, equilibrioception, and nociception. And oh, glass is back to being consdered boringly solid. I remember being fascinated to hear in class that window panes of old churches get thicker at the bottom because it 'flows'.)

From revisionist accounts of history and alternative economic models to genuinely new insights in physics and biology, there is plenty more that is rapidly changing in the human ken. I just hope teachers learn some way to deal with it.
