Evolutionary transcriptomics implicates HAND2 in the origins of implantation and regulation of gestation length

open access: yeseLife, 2021
The developmental origins and evolutionary histories of cell types, tissues, and organs contribute to the ways in which their dysfunction produces disease.

Sensory receptors in monotremes [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1998
This is a summary of the current knowledge of sensory receptors in skin of the bill of the platypus, Ornithorhynchus anatinus , and the snout of the echidna, Tachyglossus aculeatus .

The Australian Monotremes [PDF]

open access: yesNature, 1877
WITH reference to the existence of Tachyglossus (olim Echidna) in North Australia, and the recent discovery of one (or possibly two) species in New Guinea, the following account, which I lighted on a few evenings ago, when looking over an old volume of the field, seems to be of sufficient interest to warrant its transfer to the pages of NATURE.

Pectoral girdle and forelimb musculoskeletal function in the echidna (Tachyglossus aculeatus): insights into mammalian locomotor evolution [PDF]

open access: yesRoyal Society Open Science, 2018
Although evolutionary transformation of the pectoral girdle and forelimb appears to have had a profound impact on mammalian locomotor and ecological diversity, both the sequence of anatomical changes and the functional implications remain unclear ...

Electroreception in monotremes [PDF]

open access: yesJournal of Experimental Biology, 1999
ABSTRACT I will briefly review the history of the bill sense of the platypus, a sophisticated combination of electroreception and mechanoreception that coordinates information about aquatic prey provided from the bill skin mechanoreceptors and electroreceptors, and provide an evolutionary account of electroreception in the three extant ...

Tracing Monotreme Venom Evolution in the Genomics Era

open access: yesToxins, 2014
The monotremes (platypuses and echidnas) represent one of only four extant venomous mammalian lineages. Until recently, monotreme venom was poorly understood.

Identification and functional characterization of a novel monotreme- specific antibacterial protein expressed during lactation. [PDF]

open access: yesPLoS ONE, 2013
Monotremes are the only oviparous mammals and exhibit a fascinating combination of reptilian and mammalian characters. They represent a component of synapsidal reproduction by laying shelled eggs which are incubated outside the mother's body.

Species identification of Australian marsupials using collagen fingerprinting

open access: yesRoyal Society Open Science, 2021
The study of faunal remains from archaeological sites is often complicated by the presence of large numbers of highly fragmented, morphologically unidentifiable bones.

The TMJ Disc Is a Common Ancestral Feature in All Mammals, as Evidenced by the Presence of a Rudimentary Disc During Monotreme Development

open access: yesFrontiers in Cell and Developmental Biology, 2020
The novel mammalian jaw joint, known in humans as the temporomandibular joint or TMJ, is cushioned by a fibrocartilage disc. This disc is secondarily absent in therian mammals that have lost their dentition, such as giant anteaters and some baleen whales.
