E.T. and the Migrating Hunter-Gatherer: Part One

Modern humans originated in Africa some 200,000 years ago – give or take. Further on down the timeline, some band(s) of African humans eventually migrated Out-of-Africa and ultimately colonized Planet Earth. That’s the standard anthropological model. However, within that standard scenario lie a lot of anomalous issues, some of which are explored here. An attempt to resolve these anomalies is presented.

Author’s Note: The scenarios within are those of a timeframe from roughly 13,000 to 200,000 years before the present, and thus way before the era of agricultural settlements. We’re dealing with our nomadic hunter-gatherer ancestors here. Key dates are: African origin of modern humans, Homo sapiens, at about 200,000 years ago; an Out-of-Africa migration started roughly 70,000 years ago; our global colonization (except for Antarctica and Oceania) was completed by 13,000 years ago.

When it comes to humans, here defined as Homo something or other, not necessarily just Homo sapiens, colonizing the world from Ground Zero, that’s Africa, well several problems arise.

Humans (as in Homo sapiens) originated in Africa and some ultimately did, slowly, ever so slowly, migrate Out-of-Africa (not that they actually were aware of this), eventually spreading out and colonizing the world (apart from Antarctica and Oceania east of Australia and west of South America) by at least 13,000 years ago. Exactly how is not fully understood, least of all by me. The central, but not exclusive, issue I have is with respect to our ways and means of trading in being exclusively nomadic land-lubbers for acquiring sophisticated maritime abilities as well; abilities required if our global colonization scenario is to be believed.

Problem One: Boats Required but No Show-Boats Found

When it comes to human migrations, there are certain lands that have been colonized by both Homo sapiens and Homo erectus that involved crossing reasonably vast expanses of ocean – vast at least for those cultures that existed over 60,000 years ago, when, for example, Australia was colonized by what’s today known as the Australian Aborigine. Even earlier, Homo erectus island-hopped the numerous Indonesian islands as attested to by fossil evidence. In both cases, these ancient cultures had to have acquired rather extensive boat-making, sailing and navigation skills that would allow a large enough population to cross over the ocean waters, since even during Ice Age conditions, these Indonesian islands, and Australia, were still isolated by oceans.

Sailing the oceans blue: that’s a pretty big ask for primitive humans all those tens upon tens of thousands of years ago. But, there’s another way of crossing the ocean blue – we do it all the time today. We don’t sail, we fly. Perhaps our ancient ancestors were flown to Australia and the Indonesian isles! Since aerial technology is even more outlandish than maritime technology, well, perhaps the aerial technology belonged to advanced beings – ancient aliens or ancient astronauts. One other observation in favour – there are fossil finds of this or that hominid species at A, B & C. Alas, geographical points A, B, & C are separated by thousands upon thousands of miles. No fossils are found at any points in-between A & B, or B & C. An obvious explanation, they didn’t migrate between A & B and B & C at several tens of kilometres per generation; they were flown from A to B to C, thus explaining the lack of fossils in-between - but more about that shortly.

Sooner or later in your nomadic hunter-gatherer wanderings you’re going to intersect the seashore! Rivers and streams you can wade across or swim across, maybe use a buoyant log to hold on to if need be. Lakes can be walked around. But the ocean!!! The oceans offshore must have been terrifying to our very ancient ancestors, and rightly so. The ocean is nothing if not unpredictable and dangerous: from huge waves, gales, riptides, strong currents, razor-sharp rocks and shoals, sharks, jellyfish, hypothermia, and just all sorts of unknowns lurking beneath the surface to add to your terrors. The tides must have seemed to be a purely supernatural manifestation, without natural explanation, an unexplainable action of the gods somehow saying “this is our domain, keep away”.

Would you rather be high and dry 10 miles inland or 10 miles out to sea trying to keep your head above water and not ending up as fish-food? It takes way less effort sit on the beach than to swim or sail in or on the ocean, and it’s a lot safer too!

Further, in most cases with no other land in sight, you haven’t a clue what’s on the other side of the ocean, if anything (maybe it goes on forever and forever), or how far across it is to the other side, and in any event you and your band of nomadic hunter-gatherers have more pressing needs, like finding today’s food and tonight’s shelter. The coastlines and seashores offers an abundance of food stuffs and resources: shellfish, crabs, turtles, seals, seabirds, fish, even seaweed (dried for fuel). Coastlines and seashores are good.

Are you really going to stop, make a raft and go sailing out into the pure unknown out of pure curiosity, though curiosity you probably have? No, in the daily hunt for survival you’ll probably ignore the ocean and just follow the coastline – which eventually will bring you to most places. If you come to an impassable barrier, it’s probably easier and far safer to trek inland for awhile than divert resources to swimming or rafting around the barrier with all the dangers that could entail. In any event, it’s not all that east building and sailing and navigating a seaworthy boat or raft from scratch without any handy-dandy how-to manual available. Further, you can’t drink the seawater so freshwater would have to be carried on any hypothetical voyage. Do you have leak-proof containers? If so, how much do you need to take? Who knows? In any event, you don’t have boat or raft building know-how, or navigation skills nor seamanship abilities.

There are four possible or realistic routes out of Africa. Even during the Ice Ages when sea levels were lower, three involve an ocean crossing, which, I suggest our ancient ancestors would avoid. I think it is far easier, and safer, to just follow the coastline, so I opt for the sole land route, up the west coast of the Red Sea and on up either into the Levant, or back down the east coast of the Red Sea and on into Arabia. You can follow the African coastline ‘Out of Africa’ and eventually reach China, but not Australia, or Japan, or lots of S.E. Asian islands, the Channel Islands (off Southern California), Sri Lanka, etc. Yet you find ancient human and human artefact remains in these places, so our migrating nomadic ancestors obviously did build boats or rafts and sail the ocean blue and satisfy that curiosity, but the real why is unexplained – curiosity is not motive enough to put yourself in harms way. The fly in the ointment, in any event, and alas and alack, there are no boats or rafts to be found, actual remains or pictorial representations, in the prehistoric archaeological record. Boats and rafts are all probable boats and rafts; boats and rafts are assumed but not proven by any actual evidence. It’s a sort of ’Catch-22’. Boats and rafts must be, yet we can’t find them!

It must be said that because of the Ice Ages, ancient coastlines then are now underwater and presumably relevant telltale archaeology (as in remains of boats) is therefore also underwater. Even so, the issue remains that I find it difficult to believe our ancient ancestors would have been brave enough to stick their toes in the oceans without a damn good reason, yet, there were places colonized by early man that even at the height of the Ice Ages there existed no land bridges for them to cross over, say to Australia, New Zealand, Oceania, Japan, lots of S.E. Asian islands, and presumably lots of other islands, large and small. Conclusion: That’s a big anomaly that needs a resolution.

Problem Two: Paradise Lost

Crossing the oceans blue is just the start of anomalous migration issues. If money, language barriers, cultural differences, political systems, passports and visas, etc. were of no concern and you could travel to and live anywhere you wished, where would it be? Well, probably somewhere not too hot, not too cold, not too wet, nor too dry, a place where there are abundant natural resources of food, fresh water, wood, stone, and probably some sort of ascetically pleasing scenery, etc. With the exception of the scenery, all those other geographical and climatic factors would be even more pressing for our ancient ancestors with no access to supermarkets, hardware stores, air conditioning, central heating and tap water on demand. So the question arises, given a lack of population pressure way back when, a lack of pressure not driving migration away from paradise and toward hell, why did some of our ancient ancestors adopt a nomadic lifestyle in what we’d consider extreme environments, like arid regions, the tundra, etc.? 

Unlike today’s travellers, when our very remote ancestors roamed the plains of Africa, their nomadic wanderings or migrations were not geography directed. In an era where there was no radio and TV, newspapers and magazines, GPS and the Internet, encyclopaedias and travel agents, there was no knowledge of what was over the hill, beyond the horizon. Food availability directed your travels and migrations. You exhausted one patch of turf – you moved on to the next, and the next, and the next in a sort of random drunkards walk. Logic dictates that even so you didn’t wander out of paradise or a reason facsimile thereof. But eventually, like a drop of ink diffusing through a glass of water, the rest of the world, paradise, hell and points in-between, got invaded by our African out-of-towners – an invasive pest species that was to bring total death and destruction in their wake, but that’s another story. Anyway, why we colonized extremely hostile environments when more pleasant alternatives were available needs a resolution.
