This 5.5-million-year-old ancient cave was discovered in southern Romania, and it may be the strangest spot in Romania, according to our knowledge. Experts first discovered it in 1986, but we still know very little about it now.
It is thought to be a 5.5-million-year-old cave that gradually developed its own ecology through time because it hasn’t been in contact with the rest of the globe since.
There are geothermal plants here that you won’t find anyplace else on Earth since they’ve been forced to evolve on their own for ages within this cave.
Entering the cave will give you a great deal of suffering because it only contains seven to ten percent oxygen inside, compared to twenty-one percent in the rest of the world.
If you really spend more than six hours inside playing around, you will be in grave danger, since you can easily lose your life if you are overexposed to it.
But that’s not all: over 48 of the species identified here are unique to this cave, having never been seen anywhere else on the earth.
Rich Bowden, the 29th person to actually enter the cave, said that it was the cave’s severe environmental conditions that led to these unusual evolutionary choices.
