A thylacine, only extinct since 1936.

350000 years ago, just beyond the western edge of the icy Schwarzwald, spring has come to the mammoth steppe. A raven flies over a group of steppe mammoths enjoying a cold bath in the Oos river, while a Megaloceros grazes on some choice plants growing on the riverbanks. With the harsh ice age winter in retreat for a few months, a flock of greylag geese migrates north, a buzzard hunts, and a small pack of wolves observe a herd of steppe bison and some roe deer.

And here's the final art of my #PrehistoricChallenge featuring the Neogene and Quaternary.

A Woolly Mammoth (Mammathus primigenius) lost in a blizzard.

I really loved this scene, my main gripe with these kinds of Paleodocs is we just get endless segments of hunting or courtship when real animals are so much more diverse in behavior, so getting a good few minutes of a young Sabertooth goofing around with Armadillos is great.

Paleo Party time! This guest is the Dire Wolf!

GLASWEGIANS: QUATERNARY

quaternary – glaswegians Release Date: March 11th, 2022

Track Listing:

1. pavilion 2. motavia 3. handedness 4. zugzwang

glaswegians is the solo instrumental project of Michael Elder, based out of Vancouver. quaternary was written over several years from 2017-2020, and mostly recorded from his home during the pandemic. This is a follow-up release to 2017’s severance, which also featured lengthy tracks. 

Despite being only four tracks, this album is a hefty hour and two minutes long. By nature, it is not necessarily an easy listen. There are no lyrics or vocals to be found, and there are literally dozens of instruments used to create an entire symphony. Throughout there are all sorts of complex, varied time signatures – entire songs hidden within each section.

Almost fifty(!) instruments were used in the final recording, ranging from electric guitar, piano and drums, to orchestral sounds like the cello and harpsichord, to the more obscure euphonium, omnichord, and Akai EWI 5000. I’m mind blown that all of them were played by one person – Michael himself. Aside from additional drum production by Jordan Elder and mastering by Angel Marcloid, this entire album was a solo endeavor. glaswegians is a project that could easily be the work of twenty people, all done by a single individual. 

“pavilion” is a light track with a heavy psychedelic sound. It’s very cheerful all around; I could see it being played by Electric Light Orchestra, especially the ending. Sections of it sounded like Rush or Pink Floyd – indeed, the primary influence for this EP was 70s prog artists like Mike Oldfield, King Crimson, and Camel. There’s a rising sound throughout; it takes a while to get to the climax, but when it hits, it leaves an impression of the sheer magnitude that is to come. 

“motavia” is still quite upbeat, though not as much as the previous song. The middle features a lot of minimalist, slow piano work. It would not be out of place in a classical music hall. Some of it even sounds like a lullaby, something soothing to drift off to. I felt relaxed and inspired after finishing it. "motavia” is a song to get oneself focused; a mood lifter during hard times. It would also fit right in with many video games, grinding another level or finishing that quest.

“handedness” has an old-timey feel. I could see some of this being played in an old Disney film, or scoring a quirky black and white French film. Despite the old-fashioned angle, it has a timeless, universal approach. Later parts could be used in a sample or riff for a totally different genre as rap or EDM beats. The ending is in contrast to the middle: almost maximalist with a powerful, booming finish. Truly an epic conclusion, like something you’d hear as the final notes at a concert.

We close with the most cosmic and strange of the tracks. “zugzwang” is extremely fast for most of its runtime. It really feels like listening to a jazz band jam – so many moments that make this being the work of one person remarkable. There’s a lot of passion and funk present, particularly in the last five minutes. One could be forgiven for feeling as if they’re in some kind of sci-fi movie, flying across space with Sun Ra. 

Having listened to this album several times, I was able to find new things to enjoy every run through. There’s so much going on; the ambience and sheer craft means you’ll love listening to it twice, thrice, or ten times. I can’t say I listen to hour-long symphonic instrumentals on a regular basis, but quaternary helped me appreciate the stylistic approach. It’s an awe-inspiring, ambitious EP clearly made with love and care. It took several years to create, but the end results are well worth it.

Let's take a closer look at the hominin skulls in the Senckenberg Museum's human evolution room. Keep in mind this is not a linear progression through our ancestors, and more like a bunch of closer and more distant cousins.

The first one, Sahelanthropus tchadensis is seven million years old, and may very well not be a hominin at all. I've always leaned towards the hypothesis that it's a gorilla relative, not one of ours. No matter which branch of the apes it belongs to, it lived not long after the time the human-line (hominins) and the chimp-line separated, and possibly even before that point!

Ardipithecus ramidus, the first hominin from where we can start making a fairly decent family tree of our relatives. Before this point, 5 million years ago, hominin fossils are very rare, fragmentary, and difficult to assign. One of the most interesting things that does seem to emerge from these early fossils is that we have walked on two legs for a long time. Maybe even so long that our common ancestor with the chimps and bonobos did it!

Lucy represents Australopithecus afarensis, who shows up at this point (3.3 million years ago).

Australopithecus africanus, the Taung child to be precise. We're about 2.8 million years ago at this point. Australopithecines must've been such fascinating creatures.

Homo habilis, the 'handy man', named that way because when they were discovered they were thought to be the first humans who used tools. Since then, Australopithecus tools have been found, and tool use by many different animals has also been documented.

Homo rudolfensis, a population of humans who lived at the same time as Homo habilis and were notably bigger and a little brainier. Does it warrant being its own species? That depends who you ask. Splitting vs lumping is a point of contention in almost every group's biology, and it can run especially high in the field of human evolution since hominins are A very high profile and important fossils that directly relate to our own origins, and B an extremely tangled group that seems to have produced loads and loads of isolated populations and subspecies that regularly migrated all over the place and had frequent interbreeding events. Personally I tend to come down on the side of lumping them into a few major species.

Paranthropus boisei. These were basically a separate lineage of australopithecines, quite different from our own ancestors, who continued to do australopithecus things until quite recently. They were very good climbers and seem to have returned to the trees.

Homo ergaster, either a close relative or a synonym of the more famous Homo erectus. This is the point where we got really brainy, probably figured out how to make fire ourselves, and spread from Africa to Eurasia.

Homo heidelbergensis. Homo erectus and its many subspecies spread all over Africa and Eurasia and existed for well over a million years. As time marches on and evolution did its thing, we eventually start calling the ones in Africa Homo heidelbergensis. They were quite tall, positively enormous compared to little Lucy a few million years back, and they too joined in the human migrations out of Africa. From the H. heidelbergensis who moved into Eurasia we eventually get neanderthals and denisovans, while Homo sapiens evolved from the heidelbergensis populations in Africa.

And there's the neanderthals! Large-brained and creative (the first known cave paintings belong to them and they buried their dead), they were likely quite different from the brutish image we often get from them. Rather than truly dying out, their populations eventually merged with the larger Homo sapiens population once they migrated out of Africa, leaving our modern genes with a couple percent neanderthal DNA.

Homo sapiens. And that's us! Not so much the last remaining branch of the human family tree as much as several of the separate branches ended up coming back together and weaving into a single bigger branch.

And then there's these little guys, Homo floresiensis! Probably originating from a Homo erectus population that ended up on the island Flores, insular dwarfism ended up making them grow quite tiny. On their isolated island, they remained until about 50000 years ago.
