‘Living Fossil’ Coelacanth Genome Sequenced

The genetic secrets of a “living fossil” have been revealed by scientists.
Researchers sequenced the genome of the coelacanth: a deep-sea fish that closely resembles its ancestors, which lived at least 300 million years ago.
The study found that some of the animal’s genes evolved very slowly, giving it its primitive appearance.
The work also shed light on how the fish was related to the first land-based animals.
The coelacanth has four large, fleshy fins, which some scientists believe could have been the predecessors of limbs.
