Talk:Cambrian explosion

Paleozoic dates wrong?
The graphic at the top of the page: "Key Cambrian explosion events" shows the Paleozoic going back into the Ediacaran, which isnt correct - it starts at 541mya. Please fix! Fig (talk) 11:42, 30 March 2014 (UTC)

While I am here, can someone please clarify if the event *began* or *ended* 541 million years ago? Or perhaps that was its midway point...? Frunobulax (talk) 18:04, 25 July 2018 (UTC)

Too much information
Hello! I'm translating this article into Basque Wikipedia, and I think that there is some information that could be very interesting if this was a book, but it's out of the scope of this article. All the 2nd section ("Explanation of key scientific terms") is not necessary here, as this information can be read directly in the concerned articles.

I would suggest also that the sections 1.1 to 1.5 (1.1 Dating the Cambrian, 1.2 Body fossils, 1.3 Trace fossil, 1. 4 Geochemical observations and 1.5 Phylogenetic techniques) could be grouped in a section called "Scientific problems" as really don't fit totally under "History and significance". -Theklan (talk) 21:40, 6 June 2018 (UTC)

Cambrian life from outer space?
Seems many authors (over 30?) in a peer-reviewed study published in a reputable science journal (WP:RS) presented the notion that life forms in the Cambrian explosion may have come from outer space - and not otherwise - seems fringe (WP:Fringe), but worth a consideration? - in any case - Stay Safe and Healthy !! - Drbogdan (talk) 12:59, 29 December 2021 (UTC)
