Collecting and analyzing soil from a fresh Sumatran tiger paw print could help save an endangered species. informs CNN cites experts from the San Diego Zoo Wildlife Alliance.
All living organisms, including humans, release blood, skin, fur and waste products into the environment. They contain genetic material. Using DNA analysis, you can identify the person who left a trace.
This method will help track certain tigers and determine their exact numbers living in a particular area. In addition, the method also helps to monitor their state of health.
“Now, instead of saying we’ve seen about 40 fingerprints in this area, we can say that these 40 prints were left by four special tigers,” the scientists said.
Now scientists are trying to improve DNA analysis technology for more accurate identification of an individual.
