Apr-10-15  Jambow: I believe it was Polynesians that inhabited Easter Island and that is like finding the proverbial needle in a haystack compared to finding the entire continent of South America. These guys were navigating vast distances with purpose.

Bottom line is that they still located and populated hundreds of remote deep ocean tiny islands, presumably by small boat yet think they some how missed two continents that were closer to Easter Island than some of the other Islands are to each other? They were genuine mariners and I'm sure others were too. The hypothetical land bridge crossing may have never happened I wasn't there it is a story that sounded plausible and became accepted as a fact. They frequently even tell us their motivation for crossing? How would anyone know that with out record was it in their DNA?

No matter all I'm hoping for is someone to drop the oft repeated stories look at the empirical data and see if it adds up. Or at least separate what we assume from what we actually know.

Go Irina and Nemcova this is a game to see. I expect Irina to carry the day but it's not a given.

  HeMateMe: how do you know that the boats didn't originate from south America, and then branch outwards towards all of the Polynesian islands?

There is really no way to know, unless skeletons on the Polynesian islands can be carbon dated and found to be older than those of s. America.

Apr-10-15  Jambow: Interesting thought, but genetically they both appear to be different peoples with some studies reporting Polynesian admixture in Native Americans and the above mentioned Native American allele absent from Polynesians.

No matter we at least both realize they didn't have to travel by a land bridge, that travel didn't have to go only or even primarily from the east to the Americas. Bottom line is most of what is taught is unconfirmed speculation with lots of evidence to the contrary. Ancestral DNA databases and techniques are improving, statistical methods are as well, I suspect we may learn a thing or two if we are willing to follow the trail and throw out many speculation.

Apr-10-15  Jambow: Ok sorry for going on and on on a side thread.

  Gypsy: <Paddling a kayak from Monterey, California to Kahului, Maui (1987)>

Given the discussion here; this was the interview of kayaker Ed Gillet on Johny Carson Show after his Monterey to Kahului trip.

Apr-11-15  RookFile: Nothing to see here. As I said a few days ago, Krush is going to run the table and win the tournament.
Apr-11-15  Illogic: Indeed, she's on a 5.5/6 rampage. And in that one draw, she had a totally winning position!
Apr-11-15  Everett: <Jambow> <Hemateme>

Sure you two are familiar with this:

  HeMateMe: If one looks at the materials needed to build a boat and a growing community that can provide sailing expertise, it seems more feasible that the sailors left SA for the islands than vice versa.
Apr-11-15  parmetd: This tournament has the worst set of names for puns... Wang, Crush, Share, You, Ni
Apr-11-15  Jambow: <Everett> That puts some weight in what <HeMateMe> is proposing thank you.

I'm not dogmatic the problem is most of what is espoused is very much so and with barely more than plausibility as justification.

Thanks for the info.

  Penguincw: Looks like tournament co-leader Nemcova blundered. A win for Palikidze would tie her with Nemcova. Meanwhile, the other co-leader, Krush, is (enter cheesy pun-verb) Yu.
Apr-11-15  parmetd: Nazi Krush and share the Wang with Yu and ni
Apr-11-15  Everett: Jambow: <Everett> <That puts some weight in what <HeMateMe> is proposing thank you. I'm not dogmatic the problem is most of what is espoused is very much so and with barely more than plausibility as justification.

Not so fast! It actually supports both of you. Check out this paragraph from the link, under <anthropology>: <Most historians consider that the Polynesians from the west were the original inhabitants and that the story of the Hanau epe is either pure myth, or a memory of internal tribal or class conflicts.[19][20][21] In 2011 Professor Erik Thorsby of the University of Oslo presented DNA evidence to the Royal Society which whilst agreeing with the west origin also identified a distinctive but smaller genetic contribution from South America.[4] While this result has been questioned because of the possibility of contamination by South Americans after European contact with the islands,[22] further work by a team including Anna-Sapfo Malaspinas (from the Natural History Museum of Denmark) analysed the genomes of 27 native Rapanui people and found that their DNA was on average 76 per cent Polynesian, eight per cent Native American and 16 per cent European. Analysis showed that: "although the European lineage could be explained by contact with white Europeans after the island was “discovered” in 1722 by Dutch sailors, the South American component was much older, dating to between about 1280 and 1495, soon after the island was first colonised by Polynesians in around 1200."[23]>

  Penguincw: Krush has a pretty easy way to win the tournament outright: get at least a draw, and the tournament is all hers. However, she has white against Nemcova. If Nemcova wins, there'll be a 2-way playoff (Paikidze winning with white against Foisor would make it a 3-way).
Apr-11-15  Everett: A 3-way amongst the women. Just what the sport needs.
Apr-12-15  Jambow: <Everett> Interesting even more so. So people traveled great distances in various directions and land bridges were not even the primary means.

My hypothesis is that the founding populations of the Americas did not come from the east but rather some traveled westward from the Americas and this better explains the similar DNA in Siberia. That being said no doubt as is being discovered now with DNA the old stories are mostly just that stories. We should not accept a plausible explanation as being reality uncritically, rather look at the evidence and give an honest critique and accept that there sometimes are often numerous possibilities.

Apr-12-15  Jambow: I'm sticking with Irina with her main rival not participating she was the odds on favorite, although it aints over till its over.

Namcova has the most to pleased with as she way over performed thus far.

Apr-12-15  Jambow:

All right Everett I've been up to late and I'm blaming you. Interesting documentary.

Sadly all those days at sea and nobody brought a chess board.

Apr-12-15  Harvestman: Final position in Foisor vs Ni is showing as a draw on Chessdom, but is easily winning for black.
Apr-12-15  Harvestman: Ah, the official site has it as a win for black, which makes a lot more sense.
Premium Chessgames Member
  Penguincw: Looks like the top 2 games are drawn, so Krush wins by a full point, while Paikidze finishes as the only undefeated player.

Sorry for keeping you up! If you ever venture to Scandinavia you can check out the museum. Fascinating stuff.

It is my impression that there was quite a bit of masterful boating going on in the ancient days, navigating by the stars, knowing the currents inside and out, fishing with expert skill of limited tools. It was a different sort of intelligence than we have today. Quite impressive in my eyes.

Apr-13-15  Jambow: <Everett> Just kidding it was very interesting actually. I agree with your assessment.

Great job Irina and Nemcova too.

  eternaloptimist: Well Krush won yet another U S Women's Championship. This is her 7th! Nemcova had the lead for a good while but Krush played better in the 2nd half of the tourney & won it. The fact that Anna Zatonskih didn't play in it made Krush's task a good bit easier. Although Krush said in an interview during the tourney that she missed her not being in the tourney this year. Krush likes to earn her victories & is a true champ!
