Early Neolithic boat and row fragments found in Korea


The remains were originally uncovered in 2005 in Ujin but only now it seems to have reached the international media. They are made of camphor wood and are stratigraphically from the Early Neolithic period (c. 8000 years ago). 

What remains of the boat is 3 meters long and 60 centimeters wide, whereas the original ship is thought to have been at least 4 meters long. 

The artifacts show how advanced carpentry was already in that period.

Oldest Korean farm

In a related news item, the remains of the oldest known Korean farm were unearthed at Goseong earlier this year.

See: PhysOrg.

  1. Hey maju , My name is Leslie my Mtdna haplogrop is L3d1c it is from
    North Africa ,I wanted to know if you could tell me any thing about L3d1c population race when did they origin etc ..thankyou

    1. No, sorry: African lineages are not too well known (besides I do not believe in "race"). And you are off topic (try at the very least to search for something relevant, c'mon!)

    2. Anyhow, Behar found it in North Africa and I have it marked as such in this old thread: http://leherensuge.blogspot.com.es/2010/03/reviewing-mtdna-l-lineages-notes-l3-l4.html, where there is some discussion on whether if some other L3 lineages are North African or what. You may want to check.

    4. On 23andme Global similarity advanced ...
      My cousin who shares the same mtdna as I received we best cluster with the Mozabite Berbers Would this actually mean that I had a maternal ancestor in Algeria ..any help

  2. Hey Maju, Do you have access to Doron Behars' or any other MTDNA spreadsheet showing any info of my subclade L3D1C

    1. Behar materials are freely accessible (AJHG has a six-months embargo but then all papers are freely accessible), check the supplemental materials for details: http://www.cell.com/AJHG/fulltext/S0002-9297%2808%2900255-3

      I did comment L3 (and related L4 and L6) in this blog post at my old (discontinued) blog Leherensuge: http://leherensuge.blogspot.com.es/2010/03/reviewing-mtdna-l-lineages-notes-l3-l4.html

      Then I noted that L3d1c (secondary letters are uncapitalized, only the first one is capital) is found in North Africa.

      However Behar was covering a huge most diverse continent, as is Africa, with an only-so-large sample, what always leaves much room for further improvement. Not only in Africa but also in Europe and probably West Asia. For example:

      → http://forwhattheywereweare.blogspot.com.es/2012/03/claim-that-many-african-matrilineages.html → claimed several L(xM,N) as likely very old European clades, notably L1 variants but also L3d1b1a. Also I mentioned in this blogpost, that, based on HVS-I, I suspect one of the Portuguese Epipaleolithic lineages of Chandler 2005 to be L3d2. Neither is your clade but both are close (L3d-derivates).

  3. Thx.I always appreciate your knowledge

  4. You also mentioned L3d1c is found in Egypt (would that be people of the Siwa tribe-I suspect).

  5. If you can please take a look at this spread sheet of L3d1c and give me your opinion on where i stand ...I have markers 5372G & 9254G but do not share any markers with the tunisa/usa sample

    1. I must ask you to put your comments together in one next time. I cannot imagine a single good reason to post four single-line comments in a row instead of just one.

      "I have markers 5372G & 9254G but do not share any markers with the tunisa/usa sample"...

      Then it is another sublineage but in that same branch as the Tunisia/USA sample. For what I know you are the only person on Earth with it. There must be more but I do not know of any studies so detailed.

      There's a lot yet to learn studying African genetics.

  7. Thanks & wow, unique but makes things harder to find data.Im guessing that My sublineage is in NorthAfrica but scattered across from egypt to the atlantic.What would you suggest the population or exact country my sublineage would identify with looking at the data ive giving you would like to here your opinion.

    1. There has been a recent study on African mtDNA but it is by the moment pay per view (it will be accessible in six months, as all PNAS papers). I mentioned it here.

      The highlight were some L0 lineages from Zambia but the abstract also says that they sampled "500 full mtDNA genome sequences from 45 southern African Khoisan and Bantu-speaking populations", what is a great addition to the still very incomplete African mtDNA database. I doubt you will info useful for your particular case there but you never know until you check.

      Other potentially interesting (African mtDNA) recent references are this (PPV generic African mtDNA expansion) and this (open access, Chad Basin). If you access the corresponding papers, try digging in the supplemental materials and you may "strike gold", metaphorically.

      Also you may want to check the work of Etyopis, who is very specialized in African genetics and may well know something I don't.

    2. "What would you suggest the population or exact country my sublineage would identify with looking at the data ive giving you would like to here your opinion".

      One of the issues here is that there are two known distant relatives, one of which is clearly located in Tunisia but the other is from the USA, surely African-American, what implies with great likelihood (but no certainty) that the lineage is Tropical African on that side (but where from exactly? West Africa has good chances but no certainty). So most likely the overall lineage is found at both sides of the Sahara, although I'm somewhat tempted to think of it as specifically North African (I know it sounds contradictory but the available data is sparse and the same it may have migrated from South to North, several North African peoples have established themselves in the Sahel also: there's no "thick line" but a dotted one). So my best guess is West Africa (Sahel?) or NW Africa or both. Central, East or Southern Africa look rather less likely.

      But that's all I can say. Sorry not being able to help you more.

    3. As I was on it, I just checked the supporting information in the Chad Basin paper, which is open access and noticed that L3d1c, your haplogroup, is found among the Hide, the Kanuri and the Mafa (only among the many populations sampled around Lake Chad). So there is some chance that your lineage is from the SW region of Lake Chad (check the map in the paper).

      What I haven't done is to check for your particular sequence (among other reasons because I don't know it in full but also because it's work). Check supp. table 2 to compare, you may find distant cousins over there or at the very least a better overall picture of your haplogroup.

      And if you find something interesting, please leave a note, so I know that all this search has not been in vain. Best luck.

    4. PS- As I guess you're African-American, you may be also interested in this entry, which reviews a study on the overall ancestry of African-American populations (all the Americas, not just the USA), with some limitations because of the relative scarcity of data. And then of course with more time I guess that most posts of the African genetics category may have some interest as well.

  8. Thnx.I see the shawa arab is located in the same area aswell,aslo L3d originated in east africa so i doubt that it migrated from south africa to north.I believe my L3d1c originated in Northafrica and migrated south with the arabs and berbers during (The Arab Dynasty).I am also cobfused on how i would find a distant cousin on that spread.IAM also of multitacial background Mainly Native American,European,& little african (my mother is from (columbia)mesoamerica ..my family looks native ..But many people beilieve we are of Arab origin as we look,and a very nice coincedence how My mtdna is from North Africa....An example of berbers and many different ethnic groups in america during earlier times 1500-1800's(us slavery) is (Fidel Castro) his mother is cuban of Canary Berber descent.Hope u can help me find more info on my specific L3d1c i appreciate everything

    1. More than what I said I doubt I can help you more. Check the papers mentioned above and judge yourself. Good luck.

  9. Thanks Maju,but how do i actually go about finding a distant cousin

    1. You take the markers of your sequence and compare with all other known sequences in the haplogroup, reviewing every single relevant paper (especially the supp. materials) and using PhyloTree as reference.

      You did that above when you only had three "cousins" to compare with. Just expand your scope looking at the supp. materials of the papers I mentioned and whatever else you can find around.
