Authors should submit their revised manuscript as a Microsoft Word document (Word 2003 or earlier version; if you are using Word 2007, please save the file as a Word 2003 document). The manuscript should be double-spaced throughout, including the author affiliations, the Literature Cited, the figure captions, and the tables. The article should follow the style of Human Biology and should be written concisely.

The manuscript should be organized as follows. The first page should be a title page, including the title of the paper, authors’ names, complete authors’ affiliations, and key words.

The second page should contain the abstract of the paper (500 words maximum). The abstract should give a summary of the article and not be merely descriptive of it. For example, state the results and the conclusions; do not use such phrases as “The results are discussed in terms of epidemiology.” The prereview made by the editors is based solely on the abstract and title; therefore the abstract should be exhaustive and informative.

On the third page of the manuscript you should start the actual text. The text should contain the following sections: an introduction (untitled) outlining the background of your topic and stating your purpose in writing the present article; the materials and methods (the study population, statistical methods, measurement methods, etc.); the results; and a discussion,followed by a perspectives section, if needed. After the main text of your article, you should include a complete list of Literature Cited. In the text, you should cite references by author and date. In the Literature Cited section references should be in alphabetical order by author. The Literature Cited should include all references cited in the text, figure captions, and tables. Please do not pad your list with papers you do not cite. Following the Literature Cited section are the tables and the figure captions.

After the tables should be a list of figure captions. Because the figure captions are typeset, they should not be part of the actual illustrations. They should be placed on a separate page as you would the text, that is, double-spaced. You do not have to use a separate page for each caption. All illustrations should be in black and white and numbered sequentially. Keys and other internal matter should be lettered on the figure, or if possible, included in the figure caption.

Submit clear and readable originals of line drawings in addition to a PDF or jpeg files containing only the figures. Photocopies of figures are not acceptable. You should submit high-quality laser printer copies. Photographs should be clear, sharp, and of high contrast. They should be printed on glossy paper. Please keep in mind that your figures will probably be reduced to fit the journal page. Thus make sure that all lettering and symbols will be able to withstand substantial reduction and still be legible. The Press does not alter figures. Therefore what you submit is what is printed. It is to your benefit--and your readers’--to present the highest-quality figures.
