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

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.

Desertification Effects, Causes, And Examples : Top 10 List

January 5, 2015 in Animals & Insects, Geology & Climate, Humans, Plants

Desertification is a process of land-degradation by which a region becomes progressively drier and drier — eventually becoming desert. Or, to put it another way — desertification is the process by which previously biologically productive land is transformed into wasteland.

There’s actually currently something of a debate over the use of the term though. As it stands, the most widely accepted definition is probably the one that’s now printed in the Princeton University Dictionary — which defines it this way: “The process of fertile land transforming into desert typically as a result of deforestation, drought, or improper/inappropriate agriculture”


There are a number of different causes/mechanisms behind the process, such as deflation (the loss of stabilizing vegetation, and of top soil); erosion; and soil-salinity-rise (via irrigation mostly). Read the rest of this entry →
