Vertebrate ancestor had 'sixth sense'

According to studies 96 percent of vertebrates descended from ancestor with sixth sense. Sharks, paddlefishes and certain other aquatic vertebrates have another sense: They can detect weak electrical fields in the water and use this information to detect prey, communicate and orient themselves. A study in Nature Communications that caps more than 25 years of work finds that the vast majority of vertebrates about 30,000 species of land animals including humans and a roughly equal number of ray-finned fishes have descended from a common ancestor that had a well-developed electroreceptive system. According to the website this ancestor was probably a predatory marine fish with good eyesight, jaws and teeth and a lateral line system for detecting water movements. It lived around 500 million years ago. This knew finding has helped scientist fill in some gaps in the evolutionary timeline.
