Most bilaterian animals excrete toxic metabolites through specialized organs, such as nephridia
and kidneys, which share morphological and functional correspondences. In contrast, …

Cell movements are essential for morphogenesis during animal development. Epiboly is the
first morphogenetic process in zebrafish in which cells move en masse to thin and spread …

Excretion is a fundamental process for animal survival and led to the evolution of specialized
excretory organs that facilitate the removal of metabolic waste products. Excretory organs …

Acoel worms represent an enigmatic lineage of animals (Acoelomorpha) that has danced
around the tree of animal life. Morphology-based classification placed them as flatworms (…

Bilaterian animals display a wide variety of cell types, organized into defined anatomical
structures and organ systems, which are mostly absent in prebilaterian animals. …

A comparative transcriptomic analysis of eight tissue types in twenty bilaterian species
reveals the long-lasting effects of genome duplication on the evolution of novel tissue-specific …

Molecular approaches to the study of development and evolution have had profound effects
on our understanding of the nature of the evolutionary process. Developmental biologists …

The Xenacoelomorpha is a clade of mostly marine animals placed as the sister group of the
remaining Bilateria (Nephrozoa) in most phylogenomic and morphological analyses, …

Excretion is an essential physiological process, carried out by all living organisms, regardless
of their size or complexity. Both protostomes (eg, flies and flatworms) and deuterostomes (…
