Talk:Background extinction rate

It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

"biodiversity increase"? edit

I think there's a problem with this line: "Given that biodiversity has been increasing since at least 3.5 billion years ago, the background extinction rate must be smaller than the rate of speciation [3]" I read the (ancient) citation, and find no support for such a sweeping generalization. Also 3.5 million years ago coincides with the onset of dropping global temperature and first glaciation and associated extinctions, which makes the statement even stranger, and to that one can add the well-known "pull of the present" taphonomic bias wrt fossil biodiversity. I'm taking the sentence out; if any paleoecologist feels this is in error, feel free to reinstate it. The Man On The Street (talk) 02:27, 22 February 2009 (UTC)Reply

Estimates of overall rate needed edit

There are several estimates. This article needs to address this. — Preceding unsigned comment added by 192.80.64.216 (talk) 12:46, 31 March 2023 (UTC)Reply
