Understanding "Culture"

 

The world of the early Hebrew.


Dr. Alice C. Linsley

A member has asked about the meaning of the term "culture", and she would like to know "what constitutes a culture?"

When we speak of a "culture" we must recognize that people adapt to the environment, which means that the culture will reflect its environment. Desert cultures around the world have much in common. River cultures around the world have much in common. Coastal populations share many common features. The same is true for the populations of the Artic. This is one of the more profound observations of Franz Boas, the American anthropologist, whose initial studies were done among the Eskimos.

Not surprisingly, the earliest human populations lived near major water sources such a rivers and lakes. Genesis describes Eden as a vast well-watered region extending from the Upper Nile to the Tigris and Euphrates. This is the region inhabited by the early Hebrew (4000-2000 BC) who dispersed into the areas shown on this map. The oldest known site of Horite Hebrew worship was at Nekhen on the Nile.



They traveled along the rivers that interconnected in Africa during the Africa Humid Period, also known as the African Aqualithic. The rock paintings that are found across what is today the Sahara reveal that the region was once green and watered. These images show people swimming and fishing.

Noah's homeland was in the region of Lake Chad about 6000 years ago. This is the only place on earth said to be Noah's homeland by the local populations. They call it Borno or Benue, both meaning "land of Noah". The local Kanari people call Lake Chad Buhar Nuhu, meaning "Sea of Noah". The now dry Sahara was much wetter then and the Chad Basin overflowed. Indeed, from Noah's perspective, all of his territory (eretz) would have appeared to be under water.

A distinctive trait of the Hebrew marriage and ascendancy pattern drove their dispersion. Hebrew sent-away sons were to move away from the Hebrew ruler's proper heir and establish territories of their own.

Noah was probably a sent-away son. His Hebrew ancestors likely lived in the Nile Valley. Some of those Hebrew ancestors may have been cave dwellers living along the Nile River.

His culture was that of the paleolakes of Africa. Archaeological research has identified various populations that lived at paleolakes near Noah's territory. See Paul Sereno's findings at Gobero

Paleolake populations were fishing and boating cultures. This Dufuna black mahogany boat was found in 1987 in Yobe State (Nigeria) buried 16 feet under clays and sands which alternating sequence showed evidence of deposition in standing and flowing water. The dugout is 8000 years old. By comparison, Egypt's oldest boat is 5000 years old.

Peter Breunig (University of Frankfurt) specializes in African archaeology. He has written this description of the Dufuna boat: “The bow and stern are both carefully worked to points, giving the boat a notably more elegant form”, compared to “the dugout made of conifer wood from Pesse in the Netherlands, whose blunt ends and thick sides seem crude”.

Breunig added, "Judging by stylistic sophistication, Breunig reasons that, “It is highly probable that the Dufuna boat does not represent the beginning of a tradition, but had already undergone a long development, and that the origins of water transport in Africa lie even further back in time.”

Riken Plastics Surpass Conventional Plastics

 



Researchers at Japan's RIKEN Center have created a durable plastic which is fully recyclable, and it dissolves in sea water; presenting a revolutionary alternative to traditional plastics which are polluting oceans with harmful microplastics.

The new plastic from RIKEN and University of Tokyo dissolves in seawater in hours and breaks down in soil in 10 days, boosting soil health with nutrients like phosphorus and nitrogen. 

The RIKEN team was able to generate plastics with varying degrees of hardnesses and tensile strength, finding all were comparable or in some cases better than conventional plastics. This means that the new type of plastic can be customized to meet demand; hard scratch resistant plastics, rubber silicone-like plastics, strong weight-bearing plastics, or low tensile flexible plastics are all possible.

This plastic is as strong as conventional plastic but leaves no harmful microplastics. The product is a big step toward ending plastic pollution and supporting sustainable farming.

RIKEN is Japan's largest comprehensive research institution renowned for high-quality research in a diverse range of scientific disciplines. Founded in 1917, initially as a private research foundation, RIKEN has grown rapidly in size and scope, today encompassing a network of world-class research centers and institutes across Japan.

COVID-19 Confinements Clear the Air



Satellite images have shown a dramatic decline in pollution levels over China, which is "at least partly" due to an economic slowdown prompted by the Coronavirus, according to Nasa.



Daily global carbon dioxide emissions dropped 17 percent, from about 100 million metric tons to about 83 million metric tons, in early April compared with average daily emissions in 2019, researchers report May 19 in Nature Climate Change.

During the most stringent confinement periods, when only essential workers were permitted to commute, daily aviation activity shrank by 75 percent, the team reports. Surface transportation was reduced by about 50 percent, while power use shrank by about 15 percent.
