WASHINGTON (AFP) — For thousands of years, horses and donkeys have been some of our species’ most important partners. 
A new study published Thursday shows they’re also friends to desert animals and plants, by digging deep wells that provide a vital source of water, especially at the height of summer.
Biologist Erick Lundgren, lead author of the paper in Science, told AFP he first began noticing the phenomenon while working in western Arizona as a field technician studying river systems.
“People just didn’t think it was worthy of scientific attention,” said the scientist, who is now at the University of Technology Sydney.
