The eared seals (family Otariidae) are divided into fur seals and sea lions, despite a lack of cladistic support for these groups. The division is primarily based on hair morphology, and it is unknow...

Burin, Park, et al. estimate the adaptive landscape of cetacean body size over 50 million years. The landscape is quite flat, with few new peaks arising after cetaceans entered the oceans. However, tr...

Macroevolutionary adaptation of a continuous trait to different discrete states across species can be modelled using a phylogenetic state-dependent Ornstein–Uhlenbeck (OU) process. Existing infere...

Human impacts substantially affect our ability to detect and understand natural biodiversity patterns.

Cetaceans are a highly diverse and enigmatic group of animals with a well-documented evolutionary history. This Review describes the macroevolutionary and palaeobiological history of Cetacea, from the...

Abstract. Pinnipeds (true seals, eared seals and walruses) are the only mammals that can hear effectively in both air and water. How and when they achieved
