Wikipedia:WikiProject Geology/Cambrian explosion

From Wikipedia, the free encyclopedia

The Cambrian explosion task force is a group of editors aiming to improve Wikipedia's coverage of the Cambrian explosion.

Goals

[edit]

The Cambrian explosion article was reviewed by the scientific journal Nature 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 to Good article status – i.e. to meet the criteria below.


1. It is well written:

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

2. It is factually accurate and verifiable:

(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 the guide to layout;
Work in progress...
(b) at minimum, it provides in-line citations from reliable 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 contains no original research.
Fine.

3. It is broad 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 (see summary style).
Yes.

4. It is neutral: it represents viewpoints fairly and without bias.

Hopefully yes

5. It is stable: it does not change significantly from day-to-day because of an ongoing edit war or content dispute.

No disputes

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

(a) images are tagged with their copyright status, and valid fair use rationales are provided for non-free content; and
(b) images are relevant to the topic, and have suitable captions.[2]
Work in progress

  1. ^ Other media, such as video and sound clips, are also covered by this criterion.
  2. ^ The presence of images is not, in itself, a requirement for Good articles. However, if images (including other media) with acceptable copyright status are appropriate and readily available, then some such images should be provided.

Templates

Project banner

[edit]

Place {{WikiProject Geology|class=|importance=|Cambrian=|Cambrian-importance=}} onto any new article's talk page for it to be recognised and assessed under the scope of this task force. An article's assessment is generated from the class and importance 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:
