Recently, scientists made a major biological discovery in Indonesia. In a remote area of Indonesia, they found the world's only known lungless frog. This frog breathes through its skin, and scientists believe it is a case of reverse evolution where the species adapted to its environment.
The lungless frog discovered in Indonesia's Kalimantan Province has a brown body and lacks both lungs and a trachea, relying entirely on skin respiration. Initially, researchers placed the frog in a bucket of water, only for it to die unexpectedly. This unusual outcome prompted them to dissect the frog, revealing the astonishing truth.
Regarding this, biologist Iskandar commented, "This is fascinating because this species is quite primitive yet highly adaptable. It presents a paradox for the species itself and for the field of biology."
The new species of lungless frog is one of the few known lungless amphibians, with the only other known examples being salamanders and caecilians. According to scientists, the lungless frog underwent reverse evolution to adapt to its environment, reverting to primitive traits rather than being a mutant.
Scientists state that the discovery of the lungless frog helps them understand the initial evolutionary process of lungs, marking a significant advancement in biological research. They also emphasize that illegal gold mining activities in the region of Indonesia could threaten the survival of this unique species.
