Abstract

To examine temporal changes in population genetic structure, we compared the mitochondrial DNA (mtDNA) sequences of three populations that lived in the same location, Linzi, China, in different periods: 2,500 years ago (the Spring–Autumn era), 2,000 years ago (the Han era), and the present day. Two indices were used to compare the genetic differences: the frequency distributions of the radiating haplotype groups and the genetic distances among the populations. The results indicate that the genetic backgrounds of the three populations are distinct from each other. Inconsistent with the geographical distribution, the 2,500-year-old Linzi population showed greater genetic similarity to present-day European populations than to present-day east Asian populations. The 2,000-year-old Linzi population had features that were intermediate between the present-day European/2,500-year-old Linzi populations and the present-day east Asian populations. These relationships suggest the occurrence of drastic spatiotemporal changes in the genetic structure of Chinese people during the past 2,500 years.

Genetic Structure of a 2,500-Year-Old Human Population in China and Its Spatiotemporal Changes

Dear “junkscience”,

Thanks for passing on the Li Wang et al. paper, as well as the one by Brace et al. (posted in the “Prehistory Board”, under the Topic: Old World sources of the first New World human inhabitants: A comparative cranio). But…

… as you may know, and this for reasons that have been discussed in earlier posts, the PALANTH – Forum and, by extension, the Journal itself, have to abide by the “Copyright” rules of the land. While I realize that both the MBE and PNAS papers you have posted to the Forum are now freely available, they, nonetheless, fall under certain rules regarding how they can be used. For example:

Proprietary Rights Notice for MBE Online
Copyright © 2000, MBE Online by Society for Molecular Biology and Evolution.

1. The person using MBE Online may view, reproduce or store copies of articles comprising the journal provided that the articles are used only for their personal, non-commercial use. Uses beyond that allowed by the "Fair Use" limitations (sections 107 and 108) of the U.S. Copyright law require permission of the publisher.

Proprietary Rights Notice for the Proceedings of the National Academy of Sciences (PNAS)

PNAS and PNAS Online are both copyrighted © 2002 by the National Academy of Sciences of the United States of America.

    # The person using PNAS Online may view, reproduce, or store copies of the journal, provided that the information is only for their personal, noncommercial use.

    # Any copies of PNAS Online, in whole or in part, must include the copyright notice.

    # Except for uses consistent with the "Fair Use" limitations of U.S. Copyright Law, the person using PNAS Online may not: (i) distribute a copy (electronic or otherwise) of any document or file from this server without the written permission of the National Academy of Sciences, (ii) alter a copy of any retrieved, printed, or stored document or file from this server, or (iii) charge for a copy (electronic or otherwise) of any file or document from this server.

In other words, it appears, from the above “Proprietary Rights” notices, that the generous sharing of these papers with the members of the Forum, clearly falls outside the rules all Forum members have (presumably) agreed to follow.

To conclude, I should add that such rules do not really prevent us from having access to useful and stimulating information. For example:

- one can post (preferably in the Links Board, and accompanied by appropriate comments) the pertinent URL of a downloadable paper;
- one can also post Abstract(s) in any appropriate Board (under a new or old Topic); and finally,
- one is fully entitled to make reasonable use of more or less extensive quotes (this from any kind of publication) in order to initiate (or participate in) an actual discussion.

PS  It follows that I have no choice but to delete, from your otherwise interesting posts, the papers themselves. I am sure you will understand.
