Which of the following provides the best evidence that cell-signaling pathways evolved early in the history of life?

#SCPH28 | Zoology

  1. Cell-signaling pathways are seen in "primitive" cells such as bacteria and yeast.

  2. Bacteria and yeast cells signal each other in a process called quorum sensing.

  3. Signal transduction molecules identified in distantly related organisms are similar.

  4. Most signals in all types of cells are received by cell surface receptors.
