Although the evolution of tooth structure seems highly conserved, remarkable diversity exists
among species due to different living environments and survival requirements. Along with …

Turnover—constant component production and destruction—is ubiquitous in biology.
Turnover occurs across organisms and scales, including for RNAs, proteins, membranes …

Vertebrate skin appendages are incredibly diverse. This diversity, which includes structures
such as scales, feathers, and hair, likely evolved from a shared anatomical placode …

Developmental complexity stemming from the dynamic interplay between genetic and
biomechanic factors canalizes the ways genotypes and phenotypes can change in …

Background Vertebrate teeth exhibit a wide range of regenerative systems. Many species,
including most mammals, reptiles, and amphibians, form replacement teeth at a …

Dollo's law of irreversibility states that once a complex structure is lost, it cannot be regained
in the same form. Several putative exceptions to Dollo's law have been identified using …

Background Sturgeons belong to an early‐branching lineage often used as a proxy of
ancestor‐like traits of ray‐finned fishes. However, many features of this lineage, such as the …

Objectives This study aimed to summarize the clinical features of non-syndromic late
developing supernumerary teeth (LDST) and comparisons with common supernumerary …

Background Tooth regeneration depends on the longevity of the dental epithelial lamina.
However, the exact mechanism of dental lamina regression has not yet been clarified. To …

For hundreds of years, the question of why some organisms can regenerate missing body
parts while others cannot has remained poorly understood. This has been due in great part …
