Evolutionary biology

	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.

Confusing Mess

This article is badly written and confusing. The lede defines the FUCA as existing before cells, but some paragraphs imply that the FUCA was a progenote and then defines progenotes as being cells. The article also repeatedly talks of "open" and "semi-open" systems and never explains what that means. I consider myself to have a decent lay understanding of origin of life theories and I can't make any sense out of this article. I still have no clue what a progenote, a FUCA, or an open system is, whether any of them had lipid cellular membranes, and what order they are supposed to have evolved in. I am also confused whether the FUCA is supposed to have been the first lifeform or to have evolved from something else, despite its name. 198.98.201.91 (talk) 23:57, 12 September 2024 (UTC)[reply]

The FUCA is also called "compartmentalized" which is the opposite of non-cellular. Make up your mind, please! 198.98.201.91 (talk) 00:00, 13 September 2024 (UTC)[reply]
