Just because the cave is sealed now, does not mean it has been sealed for millions of years. Even for geology, 5.5M years is a long time. I don't understand how they can claim it never had connections to the outside, just because it doesn't have connections now.

"Combined with the geology and the peculiar chemistry of the cave’s water and air, the evidence pointed to a system that had been closed off since roughly five and a half million years ago."

There are also genetic drift estimates, which put the "last" outside species to enter at about that time (
One of the most recent animals recorded is the cave's only species of snail, Heleobia dobrogica, which has inhabited the cave for slightly more than 2 million years.
Earlier quoted context omitted.
Yeah it has significant groundwater inflow (like 5L/s). Nothing about this is sealed.
> Yeah it has significant groundwater inflow (like 5L/s). where did it say this? i did a double-take because the article says the opposite, and i checked the wikipedia and didnt see it there either. is there another source of info? or am i being blind?
Interesting that being sealed for 5 million years did not yield any life forms more complex than insects. Maybe sun and space are importance factors for intelligence.

All they proved is that nothing had entered since the Chernobyl accident.
