The Timeline of the Evolution of Dolphins : 55-60 million years ago the Artiodactyls were said to have been one of the first forms of a dolphin although it was on land and hadn't started living in the water just yet.

Would you like to learn more about the lives of dolphins in a fun and entertaining way? To investigate convergent evolution at the genomic level, we sequenced and performed de novo assembly of the genomes of three species of marine mammals (the killer whale, walrus and manatee) from three mammalian orders that share independently … The Cassini spacecraft left Earth in 1997 to investigate Saturn’s rings. More recently, the New Horizons spacecraft reached Pluto, one of the farthest corners of our solar system, in 2015, and the beloved Opportunity Mars rover spent fifteen years exploring the red planet. The development of tusks occurred as a part of the evolution process, and remains a part of the appearance of the walrus today.

Instead they believe they were more closely related to early Walrus.

Navarretia willamettensis and Navarretia saximontana (Polemoniaceae), new species from ephemeral wetlands of western North America. There hasn’t been very much DNA testing to prove these theories one way or another. Movie clips on the evolution of dolphins and whales. Diversity, Evolution, and Adaptation of Sirenians and Other Marine Mammals". Evolution Research News. It took almost 50 years of them struggling to evolve with their environment as well as human interactions for them to bring the numbers up high enough for us to believe they would survive.
Two examples, one simple the other more complex, will illustrate this contention. Home; PUBLICATIONS . pp.

On February 12th, Abraham Lincoln was also born. "5. Nonetheless, highly complex adaptations arise by cultural evolution even though no single innovator contributes more than a small portion of the total (Basalla 1988, Petroski 1985, 1993, 2006). The team found a clear trend for the evolution of larger and larger body sizes through time—and they evolved at an extremely fast rate.
