6000 BC: WHG hunter-gatherers bury their dead in stone cemeteries covered with shell middens in Brittany and the Targos-Sado in Portugal. Almeneders I construction phase of the Cromlech. There are many similarities between these places.
5500 BC: EEF farmers settle Iberia, initialy in a thin coastal band running along the eastern coast of present-day Spain.
5300 BC: El Trocs, a massacre of EEF individuals inland in Spain, bodies of young adults absent.
5300 BC: Early trade network of Callais objects
5000 BC: Neolithic population crash ?
5000 BC- 4500 BC: Increasing evidence of developed trade networks
4500 BC : WHG male-driven genetic resurgence. Growth of the Atlantic Megalith Culture. From here on, megalithic constructions spread across the Atlantic coastline, to Scandinavia, North Africa and Mediterranean islands.
I have found dating the first megaliths difficult, due to the number of competing claims. Dating on the Cromlech has several references, but in Portugese. Recent research suggests the oldest megaliths are in Brittany and date back to 4500 BC. I've also found the WHG resurgence hard to date, most sources just say "middle neolithic"
It does seem to me though, that the WHG at some point took over the EEF on the Atlantic seaboard. Most likely violently, given the male-dominated genetic input, drop in EEF Y-DNA, some scant evidence of EEF massacres near the front of their expansion, and the tendency towards male-dominated burials in large tombs. And it also seems to me that the Atlantic Megalith Culture expansion was what drove the WHG resurgence. Reasons for their success, where the central European EEF expansion never seemed to have experienced anything similar may have been naval ability, reliance on multiple biomes for food, extra calories from the sea allowing higher population densities, and the ability to draw upon extended kinship connection and call upon warriors from geographically distant areas on shorter notice. Although the EEF also seems to have been competent at maritime expansion.
It somehow makes me think of the Tollense battle. Huge Homeric battle, thousands of warriors from across Europe. And no records of either the war, the warriors or the policies that fought.
Things I wonder about: How much of the Atlantic Megalith Culture came from the WHGs? Language, burial customs, trade networks, maritime orientation? What came from the EEF? Calendar functions of the megaliths seem very useful for farming. Thousands of years later, Indo-Europeans in Britain seem to have treated them as useful infrastructure investments, not cultural objects. The EEF had expanded along the mediterranean coast and to the Islands of the Med, with livestock, seedcorn etc, indication considerable seamanship. The trade really seemed to take off after the agricultural transition.
How much was a hybrid culture thing?
I am rather diverging from the sites interest in genetics here I know. The genetics are just starting to show the outlines of a long forgotten story I think.
