A study conducted by University of Utah scholars and an international team of researchers is shedding light on the evolution of amphibians and other land animals.
The team studies the African coelacanth. That fish has fins that resemble limbs, and dwells in sea caves off the coast. It was thought to have gone extinct about 70 million years ago, but a fisherman caught one in 1938.
The fossil record and the availability of living species means that scientists have new information about the fish’s sense of smell, immune system and nitrogen elimination.
