Ireland's first people may have walked in... from Wales. ๐คฏ
Rock art expert Dr George Nash has found cave engravings in south-west Ireland. They're at least 15,000 years old. That's 5,000 older than any past proof of humans there.
The theory: sea levels fell in the last Ice Age. A land bridge opened between Pembrokeshire and the Rosslare coast, about 46 miles wide. Hunter-gatherers could've walked straight across.
An AI model trained on known cave sites in south Wales pointed the team to 28 possible caves in Ireland. Eight held real rock art: engravings, ochre and charcoal paintings, and lines pressed into clay by fingertips.
What do you think of this theory? ๐ง
