TheCambrian explosion task force is a group of editors aiming to improve Wikipedia's coverage of theCambrian explosion.

Goals

[edit]

TheCambrian explosion article was reviewed bythe scientific journalNature on December 14, 2005, and found to be heavily error-laden. It has since undergone substantial reworking, but successive editors have struggled to find a compromise between scientific accuracy and easy accessibility.

This task force aims to resolve this trade-off, bring the article first to a "Good Article" standard, and ultimately to a "Featured Article" status worthy of inclusion on Wikipedia's main page.

Hopefully, the task force will create many "good articles" on smaller aspects of the explosion as "colateral damage".

Approach

[edit]

The article must present the subject in a way that is easy for a complete newcomer to understand, while retaining informative content to engage the more advanced reader. This will be accomplished by creating a streamlined main article, with links to in-depth "main articles" addressing the key aspects of the explosion. It is hoped that by providing this "two-tier" approach to the article, a balance between readability and scientific accuracy can be achieved.

Work will take place in two stage: first, the articles to which the main page will link must be created, expanded, and brought up to a standard where they can act to support the main article. Once these pages are in good shape, content can be removed from the main article, which can be restructured as time goes on.

Task list

[edit]

We are currently in stage one of the construction. Using the information available in the main article, and further material as necessary, we hope to create and expand articles pertaining to all key aspects of the Cambrian explosion.

Please check the table below for an article which interests you or which you could improve. You are also welcome to add to and update the table as needs be.

Main article

[edit]

While our attention is currently focussed on the peripheral articles listed above, we are also aiming to take the main article toGood article status – i.e. to meet the criteria below.


1. It iswell written:

(a) the prose is clear and the spelling and grammar are correct;
Work in progress...
(b) it complies with themanual of style guidelines for:
lead sections
layout
jargon
words to avoid
fiction
N/A
andlist incorporation

2. It isfactually accurate andverifiable:

(a) it provides references to all sources of information, and at minimum contains a section dedicated to the attribution of those sources in accordance with theguide to layout;
Work in progress...
(b) at minimum, it provides in-line citations fromreliable sources for direct quotations, statistics, published opinion, counter-intuitive or controversial statements that are challenged or likely to be challenged, and contentious material relating to living persons;
Work in progress...
(c) it containsno original research.
Fine.

3. It isbroad in its coverage:

(a) it addresses the main aspects of the topic;
I think so – any suggestions of areas needing coverage are welcome!
(b) it stays focused on the topic without going into unnecessary detail (seesummary style).
Yes.

4. It isneutral: it represents viewpoints fairly and without bias.

Hopefully yes

5. It isstable: it does not change significantly from day-to-day because of an ongoingedit war or content dispute.

No disputes

6. It is illustrated, if possible, byimages:[1]

(a) images aretagged with theircopyright status, andvalid fair use rationales are provided fornon-free content; and
(b) images are relevant to the topic, and havesuitable captions.[2]
Work in progress

Resources

[edit]
  1. ^Other media, such as video and sound clips, are also covered by this criterion.
  2. ^The presence of images isnot, in itself, a requirement for Good articles. However, if images (including other media) with acceptable copyright statusare appropriate and readily available, then some such images should be provided.

Templates

[edit]

Place{{WikiProject Geology|class=|importance=|Cambrian=|Cambrian-importance=}} onto any new article'stalk page for it to be recognised and assessed under the scope of this task force. An article's assessment is generated from theclass andimportance parameters and helps organise relevant articles for improvement. When assessed, the class and importance parameters are filled in, like this:

{{WikiProject Geology|class=Start|importance=Mid|Cambrian=yes|Cambrian-importance=High}}

and the banner looks like this:
