The finding that creb is highly conserved would increase the probability that it is studied throughout the animal kingdom because it suggests that the gene is important and necessary for basic biological processes. Conserved genes are generally considered to be ancient, essential and typically have been maintained throughout evolution because of their vital role in enabling life.
