Wikipedia:Scientific peer review/Cambrian explosion

Cambrian explosion
After a previous peer review, I've now got a little bit of time on my hands, and am keen to prod this slowly towards featured article status. I'm going to fix the timeline soon (when I work out what's changed to break it!) and would welcome any other comments about the content and flow, in light of comments on the talk page.

Many thanks,

Nice work on an interesting topic. I have a few comments that I hope are of some use: Thanks. &mdash; RJH (talk) 21:48, 22 August 2007 (UTC)
 * The table of contents is too long. Many of the sections are only a single paragraph in length.
 * Please use "&amp;mdash;" rather than a dash to sub-divide sentences.
 * The use of "We" in "Duration of the process" is not encyclopedic. (See WP:MoS.)
 * There are a number of very short paragraphs consisting of a single sentence. Can these be merged or expanded? There are also a number of overly-long paragraphs that need to be split up for the sake of less taxing reading.
 * Several sections are lacking in citations. I look for on the order of one per paragraph for a well-documented FA. Anything expressing an opinion or something controversial probably needs a cite.
