The ability to sense and localize sound is so advantageous for survival that it is difficult to
understand the almost 100 million year gap separating the appearance of early tetrapods …

Placental mammals occupy a larger morphospace and are taxonomically more diverse than
marsupials by an order of magnitude, as shown by quantitative and phylogenetic studies of …

The multiple skeletal components of the skull originate asynchronously and their
developmental schedule varies across amniotes. Here we present the embryonic …

Carnivory has evolved independently several times in eutherian (including placental) and
metatherian (including marsupial) mammals. We used geometric morphometrics to assess …

Within mammals, different reproductive strategies (eg, egg laying, live birth of extremely
underdeveloped young, and live birth of well-developed young) have been linked to …

Background The phylogenetic position of turtles is the most disputed aspect in the
reconstruction of the land vertebrate tree of life. This controversy has arisen after many …

The contrasting evolutionary histories of marsupial and placental mammals have often been
attributed to their different reproductive strategies. The speciose placentals develop mainly …

Staged embryonic series are important as reference for different kinds of biological studies. I
summarise problems that occur when using 'staging tables' of 'model organisms' …

We investigated the development of the whole skeleton of the soft‐shelled turtle Pelodiscus
sinensis, with particular emphasis on the pattern and sequence of ossification. Ossification …

Abstract Using the Standard Event System (SES) to study patterns of vertebrate
development, we describe a series of 17 embryos of the pleurodire turtle Emydura …
