The answer is "PET scan" or "PET-CT".
PET scan or positron emission tomography uses the technology behind conventional CT scans but performs to quantify the function in specific parts of organs (i.e. brain). The patient will be given a positron emitting substance most commonly fluorodeoxyglucose or FDG via intravenous injection. After which, the patient will go to the PET machine and the PET machine will measure the positron emitted throughout the body. Positron is well correlated to the function of a specific part of an organ.
An example of serious poaching problems is the diminishing population of Tigers.
For example in India, this has severely affected the survival-probability of tigers. There were 20000 Tigers in India in the 20th century, and now there are only 3000. This shows the severity of the problem. The government is now taking serious steps against the poachers.
This is an organ that served a purpose in the distant ancestor of an organism, but is not longer pertinent in the presently existing, recently evolved, organisms.
