Despite its inhospitable nature, the world’s tallest peak is teeming with life
In addition to the foot traffic, climate change is also straining the mountain, which is why researchers wanted to create a baseline for its biodiversity. Understanding what life exists on Mount Everest now will help scientists track changes in the future.
Seimon’s key to finding signs of life was collecting DNA from pools of thawed water. All living things routinely shed environmental DNA, or eDNA, into the surrounding air, water and soil. Scientists can match up a snippet of unknown eDNA with existing data to find out what organism it came from, in the same way that a library barcode tells librarians information about a book.
A taxonomic order is a classification that helps scientists chart how individual organisms are distantly related to each other. For example, humans are classified as, but also fall under the family Hominidae and the order Primate, which also includes lemurs, monkeys, and apes.
