Accelerated Evolution of Limb-Related Gene Hoxd11 in the Common Ancestor of Cetaceans and Ruminants (Cetruminantia)

G3: Genes, Genomes, Genetics, 2020
Reduced numbers of carpal and tarsal bones (wrist and ankle joints) are extensively observed in the clade of Cetacea and Ruminantia (Cetruminantia). Homebox D11 (Hoxd11) is one of the important genes required for limb development in mammals. Mutations in

Assessing Cetacean Habitat Suitability in the Northeast Pacific From Citizen Science Data

Journal of Biogeography, EarlyView.
ABSTRACT Aim Citizen science is an important source of biodiversity information, particularly for gathering information on species distributions across large geographic areas. However, there are challenges with spatial and species biases, and variation in effort in citizen science data.

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

Journal of Anatomy, EarlyView.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

New Skeletons of the Ancient Dolphin Xenorophus sloanii and Xenorophus simplicidens sp. nov. (Mammalia, Cetacea) from the Oligocene of South Carolina and the Ontogeny, Functional Anatomy, Asymmetry, Pathology, and Evolution of the Earliest Odontoceti

Diversity, 2023
The early diverging, dolphin-sized, cetacean clade Xenorophidae are a short-lived radiation of toothed whales (Odontoceti) that independently evolved two features long thought to be odontocete synapomorphies: the craniofacial and cochlear morphology ...

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

Experimental Physiology, EarlyView.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...
