Hard dental tissues possess a complex hierarchical structure that is particularly evident in
enamel, the most mineralised substance in the human body. Its complex and interlinked …

All modern mammals are descendants of the paraphyletic non-mammaliaform Synapsida,
colloquially referred to as the “mammal-like reptiles.” It has long been assumed that these …

Mineralized tissues, such as bones or teeth, are essential structures of all vertebrates. They
enable rapid movement, protection, and food processing, in addition to providing …

Endothermy underpins the ecological dominance of mammals and birds in diverse
environmental settings 1, 2. However, it is unclear when this crucial feature emerged during …

Living mammal groups exhibit rapid juvenile growth with a cessation of growth in adulthood.
Understanding the emergence of this pattern in the earliest mammaliaforms (mammals and …

Global climate patterns fundamentally shape the distribution of species and ecosystems. For
example, Bergmann's rule predicts that homeothermic animals, including birds and …

After the end-Cretaceous extinction, placental mammals quickly diversified, occupied key
ecological niches, and increased in size,, but this last was not true of other therians. The …

We use synchrotron x-ray tomography of annual growth increments in the dental cementum
of mammaliaforms (stem and crown fossil mammals) from three faunas across the Jurassic …

As evolutionary biologists, we live in exciting and promising times. The material basis of our
science is growing at an unprecedented rate; fossils preserving structures we thought …

The evolution of modern human reproductive scheduling is an aspect of our life history that
remains vastly uncomprehended. The present work aims to address this gap by validating a …
