Part 2/10:
Around 8,000 years ago, the Black Sea was predominantly a freshwater lake rather than the saline sea we recognize today. Research indicates that during this time, the immense water bodies in the region overflowed due to natural causes, with dramatic geological shifts reshaping the landscape. The evidence of ancient freshwater mollusks found in the sediment of the Black Sea suggests a thriving ecosystem supported by a river network that contributed to its freshwater state.
