	Evolutionary biology portal This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

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)[reply]

%%%%%%%%

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)[reply]

Cambrian life from outer space?

Seems many authors (over 30?) in a peer-reviewed study published in a reputable science journal (WP:RS)^[1]^[2] 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)[reply]

coevolution subsection - ecological explanation

After the ‘increase of size and diversity of planktonic animals’ section there is a paragraph on coevolution, is that meant to be a separate section?

Would this paragraph sit better elsewhere? Or is it even necessary in the first place? Especially considering the section on evolutionary arms races. Thoughts? Watopia (talk) 13:42, 12 December 2024 (UTC)[reply]
