Ancient Seafaring — Neanderthals Sailing The Mediterranean 100,000 Years Ago; Prehistoric Travel & Cross-Continent Exchange; & The Reality Of Archaeological Evidence As Compared To Pop Culture Assumptions

November 25, 2016 in Humans

Ocean open waters

The subject of prehistoric seafaring, and the technology of ocean-worthy ships, is a highly contested one. Conventional knowledge says that the ability to travel long distances across oceans is a uniquely human ability, and a modern one at that. But actual archaeological evidence shows something else entirely — a situation whereby seaworthy ships have been around very possibly for longer than “homo sapiens” have.

One where Neanderthals, and likely Denisovans as well (as well as other various “archaic” hominids around at the time, many of which have likely left some of their genetics behind in modern humans, just as the aforementioned two did), had been making use of the technology far back into prehistory.

Lichen Growth Patterns, Antarctica, & The Future Of The Anthropogenic World

November 14, 2016 in Geology & Climate, Humans, Plants

Antarctic lichen white

The lichen in the image above presents an interesting visual doesn’t it? Rapid growth outwards with death spreading from the origination point in the center as well, following at a regular pace behind the spread of new growth. Probably one of the most fundamental patterns in the universe, especially with regards to “life.”

Neanderthals & Denisovans — Who Were They? Comparison Of Evidence Against Pop-Culture Projection

November 6, 2016 in Fossils, Humans

Neanderthals. Since the term was first coined more than a century ago, it has often been used to refer to people of supposedly low intelligence and brusque manner. But is there any truth to these characterizations?

Were the so-called Neanderthals, that lived in Europe, the Middle East, and Northern Asia for possibly more than half a million years — back when the weather was, going by the evidence, periodically far more extreme than it now is, and when enormous and intelligent carnivores such as cave hyena, cave lions, and others, actively hunted people — truly stupid? (Cave hyena and cave lions were much larger and more numerous than their modern equivalents). What about the so-called Denisovans?

Would that even have been a possibility? If a modern human was to be plucked out of the highly insulated, and relatively predictable, modern world and put in the place of a neanderthal would they actually behave more “intelligently?” Would a modern human behave more intelligently than a neanderthal during a hunt? In a fight? In small-scale warfare?

The truth, as noted by many of those in relevant fields, is that the behaviors associated by most modern people with “intelligence” are cultural solutions, not individual/genetic ones. They’re solutions of specialization and hierarchy. Solutions based on agriculture, food surplus, professional armies, relatively static social and symbolic structures, and deep enculturation.

Solutions of domestication in other words.

While on the mass scale you could consider these solutions to be effective ones (that will depend on your opinion of mass deforestation, desertification, extinction, and anthropogenic climate change), they don’t truly relate to increased individual intelligence — just to a greater focusing on specialized knowledge, and participation in a larger system that one doesn’t actually have direct knowledge of. (And they seem to have the effect of decreasing a sense of personal responsibility for one’s actions, neighbors, and the wider world, as well.)

Denisovans — Fossils, Genetics, Artifacts, & Speculation

November 6, 2016 in Fossils, Humans

(This article is actually the second part of the Neanderthals & Denisovans — Who Were They? Comparison Of Evidence Against Pop-Culture Projection article, that had to be split because of length. Head over to that article for the preface and further information.)

The “Denisovans” receive their name from the Denisova Cave located in south-western Siberia, in the Altai Mountains. The cave itself has received its modern name owing to a Russian hermit by the name of Denis that lived there in the 1700s.

While the cave had been explored before, it wasn’t until 2008, when Michael Shunkov from the Russian Academy of Sciences and other Russian archaeologists from the Institute of Archaeology and Ethnology of Novosibirsk explored the cave, that hominid remains were found.

Altai Denisovans cave denisova

To be particular, in addition to artifacts, including a bracelet, the finger bone of a juvenile hominin was discovered. The artifacts were dated using radiocarbon and oxygen isotopes to sometime around 40,000 Before Present. A bone needle found at the site at a later point has been dated back to 50,000 BP — making it the oldest needle yet found anywhere in the world.

Solar Photovoltaic Energy Systems Explained — Solar PV Panels, Cells, Modules, & Science Of The Photovoltaic Effect

June 5, 2016 in Humans, Space

Solar photovoltaic (PV) technologies are becoming ubiquitous in many parts of the so-called developed and developing worlds it seems. Even in places as seemingly different as Australia, India, Chile, the US, and China, various solar energy technologies have begun to be deployed on the mass level — whether residentially, commercially, or on the industrial-scale (utility-scale power plants).

Who in the urbanized portions of the modern world hasn’t seen a residential solar PV system on the roof of a house? Or an image of a solar PV system connected to a satellite in the far upper-atmosphere? Or an image of a huge industrial-scale solar PV power plant sitting in the desert?

A tipping point has seemingly been reached, wherein the technology has become a notable part of the public consciousness — rather than simply a concern of those in specialized fields of engineering or physical science.

With that in mind, I put together the article below to present a basic overview of current solar PV technologies, and of the science behind the photovoltaic effect itself. Enjoy.
