To combat wildlife-related crimes on an international scale, DNA forensics techniques have been used to identify which species have been the victim of illegal trafficking activities.

Some five years later in October 2020, a group of scientists from Germany and China took up the study and concluded that there might in fact be a fifth Asian pangolin species.
