AMPLE FOSSIL EVIDENCE. "A number of important fossil finds in the 1980s to 2000s revealed several forms that displayed an elegant sequence of incremental adaptations to life beneath the waves. Since then, the evolution of cetaceans has emerged as an example of one of the most well-documented phenotypic transitions in the vertebrate fossil record." https://lnkd.in/d-3T5AM View in LinkedIn

TRANSITION TO LAND. "Many amniote groups (e.g. sauropterygians, squamates, cetaceans, sirenians, pinnipeds) made the evolutionary transition from a fully terrestrial to a semi- or fully aquatic life. This required major morphological and physiological changes that are best developed in the most specialized aquatic forms, like extant cetaceans and sirenians, which now live totally independent of the terrestrial environment." http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0118409 View in LinkedIn

FRAGMENT FROM NATURE explores the remarkable story of the largest and biggest-brained creatures on earth, who after accomplishing the monumental transition from the water to land, returned to the sea: namely the whales. This involved massive changes in their reproduction, anatomy, metabolism, physiology, social life, and feeding behavior. It is a stunning story of the plasticity of organisms to evolve, and then reverse the evolutionary step. View in LinkedIn

SMELL AND TASTE. "We showed that, though mysticetes possess functional olfactory bulbs, they had lost the D domain of the olfactory bulb during the Eocene Epoch. In addition, all modern whales have lost the functional sweet, umami and bitter taste receptors before the Odontoceti-Mysticeti split." https://lnkd.in/dcqHGKG View in LinkedIn
