There is evidence and speculation that this cultural transmission of behavior has affected gene distributions. Some ancestors of modern whales and dolphins would have lived at the same time as each other, and likely interbred between species. Of course, the evolution of whales and dolphins (and indeed all life) is not a straight line. Over many years these animals have gone from land dwellers to deep-sea divers.

Whales and dolphins (Cetacea) have excellent social learning skills as well as a long and strong mother–calf bond. When you look at the movements of fish, their spines move horizontally. Dolphins have a three-chamber stomach just like a cow or deer, showing further proof of its evolution of a terrestrial ancestor. The process of evolution can be very slow, and it allows living creatures to develop an anatomy that is structured to thrive in their environment. Renal System . 0. Various extinct dolphin-like families flourished belonging to Kentriodontidae, which were small to medium-sized toothed cetaceans and thought likely to include ancestors of some modern species… Throughout the centuries, these animals have gone through drastic changes to become the modern day dolphin. Probably one of the most important difference between land mammals and dolphins is the way they communicate/vocalize. Evolution Of Dolphins The dolphin is a charismatic, intriguing and lovable creature. Renal System . It is believed that the ancestors of dolphins that we know today entered the water about 50 million years ago. One stomach stores food and the other digests it. Renal System . [63] Based on a 2014 study, the population of Indo-Pacific bottlenose dolphins ( Tursiops sp.) These amazing creatures are considered one of the top predators in the marine ecology system. They have evolved to be well suited for their aquatic environments. Evolution of dolphins. The most widely recognized species are the common and bottlenose dolphins (Delphinus delphis and Tursiops truncatus, respectively).The bottlenose, characterized by a “built-in smile” formed by the curvature of its mouth, has become a familiar performer in oceanariums. Then digestion happens in the second stomach and in the third stomach takes care of the rest of digestion before empting out into the intestinal region.
A fossil of an ancient giant tusked dolphin lacks the extra vertebrae and short pectoral bones that make fast swimmers of dolphins and baleen whales, which later independently evolved these traits Dolphins are popularly noted for their grace, intelligence, playfulness, and friendliness to humans. Then digestion happens in the second stomach and in the third stomach takes care of the rest of digestion before empting out into the intestinal region. You simply HAVE to sea how this deep conspiracy will end.
There only a few that live in the water so it might be logical to conclude that dolphins evolved from land animals.
