Contradiction within the "biochemical mechanisms" paragraph
The "biochemical mechanisms" paragraph seems to contain a contradiction. It says both "It tended to exclude sodium and concentrate potassium by means of specific ion transporters (or ion pumps)" and "it is inferred that LUCA had a permeable membrane without an ion pump." If these are two competing hypotheses, this should be made clear, and otherwise the mistake should be corrected. Lounalune (talk) 08:50, 31 March 2026 (UTC)
