When did fish come on land?

The first fish that stepped onto land more than 350 million years ago wasn’t a fluke. Our ocean friends may have evolved the ability to come out of the water at least 30 times over the ages, according to a new study of the diversity of amphibious fish alive today.

What animal did fish evolve from?

The first ancestors of fish, or animals that were probably closely related to fish, were Pikaia, Haikouichthys and Myllokunmingia. These three genera all appeared around 530 Ma. Pikaia had a primitive notochord, a structure that could have developed into a vertebral column later.
