French Scientists discover World’s oldest structure built by Neanderthals about 170,000 years ago

Bruniquel cave suggests that people outside Africans were developing their own symbolic system and had cognitive abilities.

So deep inside the cave, it was only darkness that prevailed and sunlight was just a dream. The mysterious caves discovered recently, has ceiling dripped with mineral-laden water and has spiny stalagmites on the floor. While the structures remains a mystery, their creators are not.

  • Neanderthals were subspecies of humans who lived 400,000 to 40,000 years ago. One in Africa (Homo sapiens) and another in Eurasia (Homo Neanderthalensis). Both were same in terms of technological development, knowledge, and spirituality. The recent discovery confirms that they knew construction works and made structures that can be dated back to 175000- 50,000 years ago.
  • Neanderthals were the only group present at that time in western Europe. So this discovery provides the direct link regarding their building abilities. This also proved that they explored underground.

  • In the 1990s, a French scientist explored the Bruniquel cave but he died in between his research and was not able to complete it.Now 23 years later a crew of scientists and Geologist Dominique Genty with France’s National Center for Scientific Research (CNRS) have found this mysterious caves deep down into 1,000 feet. What is now western France is a twisting cave 30 miles underground. Researchers said that the discovery has helped them in understanding the traditional Neanderthal culture.

  • Bruniquel cave was discovered in 1992. It was found in the dark reaches 1,102 feet below from the cave’s entrance. The cave was full of paintings. One of the discovered ring structures is about 7 feet in diameter. However the other one is around 15 – 22 feet in diameter. These rings are cracked and blackened which proves that they were firstly heated by fire.
  • Scientists found more than 400 stalagmites of the same size stacked together to form walls of 2 mysterious circular structures. (Stalagmites are the mineral spears that rise up from the ground; stalactites are the hanging ones.)
  • This piece of work is totally a blunder. It is way more complex than what was thought of those underrated hominid species (Neanderthals). This also proves that they were socially more complex than classic.

  • Scientists who were able to explore the Bruniquel cave such as Jaubert told that “This certainly was a collective work, and required at least a minimum of social organization. Some had to carry torches, some had to move and transport materials, some had placed them in this specific configuration, and so on.
  • One can totally assume that the cave structures represent some symbolic or ritual behaviour or maybe they were served for domestic purposes. The burn patterns inside the cave resemble that the structure made such that it itself light on fire. Scientists also found burned pieces of animal bones which indicate that they could have been used as torches.
  • Though modern Africans dominated the world after they crossed into Eurasia (nearly 80,000 years ago), Bruniquel cave suggests that people outside Africans were developing their own symbolic system and had cognitive abilities.

    This is totally strange !!! The way they built those caves were just amazing ! Didn’t know our ancestors were this much talented ..

Spacecraft Test Runs into Serious Problems, Smoke All Over SpaceX in Florida

"Ensuring that our systems meet rigorous safety standards and detecting (issues) like this prior to flight are the main reasons why we test"

Thick plumes of smoke rose over a SpaceX facility in Florida during a test fire of a Crew Dragon spacecraft and the issue was serious, it could derail plans to fly astronauts aboard the capsule later this year, the media reported.

SpaceX, which was founded by billionaire businessman Elon Musk in 2002, said the craft was undergoing a “series of engine tests” at a facility in Cape Canaveral on Saturday, and something went wrong during the final stretch, CNN reported.

SpaceX will work with NASA to determine what caused the issue. No injuries were reported.

“Ensuring that our systems meet rigorous safety standards and detecting (issues) like this prior to flight are the main reasons why we test,” SpaceX said in a statement.

Crew Dragon is already overdue and more delays could make things tricky for NASA.

It was scheduled to conduct a key test of its emergency abort system in June. And its first crewed mission, which will carry astronauts Doug Hurley and Bob Behnken, was slated for July, though NASA recently said that timeline was under review.

NASA has also decided to ask the private sector to design and build a new generation of spacecrafts.

SpaceX and Boeing, which is building a vehicle called Starliner, were awarded contracts worth up to $2.6 billion and $4.2 billion, respectively, in 2014. Both capsules were supposed to start flying in 2017, but they have been hampered with delays.
