Question

Quizplus · Accepted Answer

Comparisons of choanoflagellate and animal genome sequences have shown that key steps in the transition to multicellularity in animals, such as cell adhesion and cell signaling, involved new ways of using proteins or parts of proteins that were encoded by genes found in unicellular protists such as choanoflagellates, rather than multicellular eukaryotes, unicellular bacteria, or unicellular archaea.
