The CIIMAR researchers published the study “Losing Genes: The Evolutionary Remodeling of Cetacea Skin” in the international magazine Frontiers in Marine Science, demonstrates that the adaptation strategy of these mammals to the aquatic environment is largely based on the loss of genes. We are used to thinking that evolution occurs only in the direction of greater genetic complexity. However, cetaceans are a living proof that evolution occurs continuously, and that the loss of genes is part of the adaptive process.
