Will nominate some of your articlesEdit

Greetings Chiswick Chap, I would like to nominate some more of your recent Good Articles, as I found them to be very interesting. I'm thinking of Sundering of the Elves and either Amritasiddhi or Yoga nidra, depending on which of the latter yields the better hook. I wanted to let you know in advance, and also clarify that I will address any issues that arise during the nomination; it was unfair to burden you with it on Isildur. I will only contact you if there is anything that I absolutely can't do myself (e.g. for lack of sources). Thank you again for all these quality articles! –LordPeterII (talk) 14:28, 16 September 2022 (UTC)

Revert edit in AbiogenesisEdit

Hi Chiswick Chap, may I ask you why your last edit on Abiogenesis was a reversion wherein an interesting contribution was deleted/reverted. It states that "LUCA find that it was not a thermophile but rather a mesophile" with reference to work of Patrick Forterre, who is an authority in this field. The text that was reverted stated also that LUCA might have been an heterotroph rather than an autotroph. I just happen to note your revert and I am sorry the text is not visible anymore in the article. It might have been an edit from Patrick Forterre himself or from Koonin. The text you reverted is in this version Thank you Phacelias (talk) 07:13, 20 September 2022 (UTC)

Phacelias: Thank you for asking. The reason is that the material is in LUCA and doesn't need to be repeated bodily (some might say "spammed") into multiple articles: the coverage of LUCA in Abiogenesis is a brief summary, and must necessarily be far shorter than the LUCA article itself, and cited to fewer sources. Abiogenesis is already a long article at the top of a substantial tree of articles, i.e. there is a hierarchy of "main" or "further" articles branching off from many of its sections, so obviously it is not appropriate to try to describe every change in every detail in every subsection at this high level. If you consider that the edit reflects a really important change, which sounds plausible, then you should make the smallest possible modification to the lead (summary) section of LUCA (to reflect the material added further down in that article), and then reflect that summary change in Abiogenesis, which I certainly won't oppose. On the edit's authorship, obviously we have no knowledge of who the IP may have been; nor are we necessarily keen to encourage people to report their own work as that brings a variety of issues along with it.
