This suggests that the majority of bacteria may be using other mechanisms to avoid freezing or possibly are non-functional at sub-zero temperatures. We propose building on our previous work to ascertain if AFP occurrence is characteristic of particular taxonomic groups, or whether its evolution is random among different species.
