Likely Beaker in Looe

Following the untimely passing of Jean Manco, a fitting follow-on in the West Country.

Dr. Katherin Frieman of Austrailian National University begins excavation Easter Sunday on an Early Bronze Age barrow outside the fishing village of Looe in Cornwall. Heritage Daily and Science Daily.

It sounds like a respectable grave in tin country, hopefully Dr. Frieman will keep the newspaper photographers busy!

*Update 4/19.  Excavators discovered a burial urn.  Will add link later.

Jean Manco (in memoriam)

I just read from Anthrogenica that Jean Manco passed away Palm Sunday from cancer.  Very sad to hear.

She wrote several books about the peopling of Europe and she commented on Beakerblog a few times.  Jean also wrote about the architectural history of Bath and Bristol and spent her career in the West Country.


Funny how things work, sometimes we cross paths in different times and in different ways.  She was an expert on Bath Abbey.  Several of my ancestors are buried in the Bath abbey, and I'm grateful for Jean and those that preserve the past and seek to learn more about it.

Her avatar in various forums and websites was the Owl of Athena, which had a special significance to her in the quest for ancient truths and appreciation for wisdom and the arts.  She will be missed.


Sincerest Condolences to her family.

Eursasians, Iberomaurusians & Bell Beakers

With some new genomics data coming out of North Africa, let's try and wring out some potential implications for our interest, the Beaker Phenomenon. (Pleistocene North African genomes link Near Eastern and Sub-Saharan African human populations" Van de Loosdrecht et al, 2018)



Here's the recent history of West North Africa based on the last several studies.

1.  Iberomaurusian is an ancient, distinct and persistent ancestry in northwestern and northcentral North Africans.  Both Natufians and Iberomaurusians have a low (6-7%) affinity to Yoruba, but Yoruba itself has a chunk of something weird in about the same frequency.  A ghost may be lurking the corridors.
Anyhow, the picture is somewhat muddled for this genetic group since we're still mostly using modern Africans to model ancient and highly diverged ones.  The important takeaway though is this, we can firmly name those components associated with the local Paleolithic and any newcomers.

2.  In the epi-Paleolithic/Neolithic transition around the coast of Morocco, the first Cardium Neolithic ancestry significantly adds to Iberomaurusian rather than replacing it.  We see this in Fregel et al, 2017.
That's important because if any Neolithic population were to leave this area and venture into Neolithic Europe, it would certainly carry this Iberomaurusian component to some minor degree.  If Early Neolithic Atlantic Europeans don't have any trace of this in future analyses, then that severely challenges any role North Africa would have in the Neolithization of the western coast of Europe.

3.  A very strong pulse of Continental European ancestry enters Late Neolithic North Africa that appears proportionally similar to some populations in the Middle Neolithic of France and Germany, notably the Salzmunde and Baalberge. Fregel et al, 2017 This is where a lot of questions keep coming back.

First of all, the maternal profiles of some Oasis Berber and Canary populations are similar to the haplogroup frequencies associated with some MN populations of Western Europe.  It's clear there is some ancient shared ancestry beyond blood alleles and mtdna, and no it's not Roman or Medieval.

When we look at the ethnogenesis of Fula people in the Senegal-Gambia region, we have several odd things to look at.

It looks as if R1b-V88 in North Africa comes recently from Southern Europe, which itself is not surprising.  What is surprising is that the time frame in which V88 would branch from Southern Europe (Sardinia?, this study; Iberia?) and that it puts us within an archaeological timeframe in which there is heavy communication between Iberia and NW Africa.  In the Beaker period, there appear to be cultural inflows and outflows, but a lot of directionality in the Beaker period.  Then there is the presence of T-13910 in Africa which needs some splain'n.

Correct me if I'm wrong, but I believe all of the Barcelona Bell Beakers were T-13910, which is interesting given the fact that the same Paris Street Beaker males were also R1b-V88 or close.
There's many aspects to this, but at this point I don't care.  Bring forth the DNA!!

Bell Beaker Using RADON-B

Data nerds will like this website,  RADON-B
They have about 222 Beakers in the database along with reference material for each individual.  For large archaeological complexes that were migratory (and whose data is spread across 20-something languages), this can be a handy tool.

Snip of Kornice Beaker from RADON-B
Understanding how to interpret the data is necessary to make any useful sense of it.  Of those that understand it, Beakers have been shown to forma cultural cline from Southwest Europe to Northwest Europe.  (One of RADON-B's contributors is Johannes Müller, who along with Van Willigen, established that directionality in 2001.

It is curious to see a number of early dates in other places, such as the Netherlands and Hungary.  The earliest Beaker date appears to be in Csepel-Háros, but Muller and Van Willigen consider these contexts, source materials and data quality in the larger picture (page 73).


A lot of folks are in this database which can be sorted by date, geography, or cultural attributes.  You can export a selected group (Beakers) directly into an excel spreadsheet for analysis.  Since I hate math and have no time, it won't be me.  Good luck.
