Cetacea (whales, dolphins, and porpoises) is a model group for investigating the molecular
signature of macroevolutionary transitions. Recent research has begun to reveal the …

The transition from land to water in whales and dolphins (cetaceans) was accompanied by
remarkable adaptations. To reveal genomic changes that occurred during this transition, we …

Marine mammals have highly specialized physiology, exhibited in many species by extreme
breath-holding capabilities that allow deep dives and extended submergence …

Hypoxia was a major challenge faced by cetaceans during the course of secondary aquatic
adaptation. Although physiological traits of hypoxia tolerance in cetaceans have been well …

Cetaceans are a group of secondarily adapted marine mammals with an enigmatic history of
transition from terrestrial to fully aquatic habitat and subsequent adaptive radiation in waters …

Owls (Strigiformes) evolved specific adaptations to their nocturnal predatory lifestyle, such
as asymmetrical ears, a facial disk, and a feather structure allowing silent flight. Owls also …

Myoglobin (Mb) is an oxygen binding protein found in vertebrate skeletal muscle, where it
facilitates intracellular transport and storage of oxygen. This protein has evolved to suit …

Cetaceans exhibit physiological adaptations that allowed the transition to aquatic life,
including a robust antioxidant defense system that prevents injury from repeated exposure to …

Extant cetaceans, such as sperm whale, acquired the great ability to dive into the ocean
depths during the evolution from their terrestrial ancestor that lived about 50 million years …

Myoglobin (Mb) is highly concentrated in the myocytes of diving mammals such as whales
and seals, in comparison with land animals, and its molecular evolution has played a crucial …
