Lut Desert (Dasht-e Lut) is a desert in southeastern Iran. The inner part of the desert is almost devoid of plant life. Many researchers believe the Lut desert is extremely unfavourable for life. However, adventurers and scientists who travelled to Lut reported evidence of various animal life, including insects, reptiles and desert foxes.
The puzzle is that how their food chain completes without plants. The response may depend on a unique and terrifying phenomenon; in the wilderness, the carcasses of dead birds are abundantly found.
A few years ago, Iranian scientists conducted a research on migratory birds entering the Lut desert due to wandering or deviation. The result showed that the death of these birds is the basis of the desert due to the intense heat coming down from the sky. In autumn, just after the intense heat of the summer, little evidence of life is found.
