What evolutionary mechanisms might account for the origin and persistence of cell-to-cell signaling systems in unicellular prokaryotes?

Answer 1

yes

Answer 2

The origin of cell-to-cell signaling systems in unicellular prokaryotes can be attributed to selective pressure for cooperation and coordination within populations. Persistence of these systems may be maintained through positive selection for improved fitness benefits, such as resource sharing or defense against competitors. Evolutionary mechanisms like horizontal gene transfer and gene duplication & divergence could also contribute to the diversity and complexity of cell signaling systems in prokaryotes.
