The question of why animals vary in their ability to regenerate remains one of the most
intriguing questions in biology. Annelids are a large and diverse phylum, many members of …

Regenerative abilities vary dramatically across animals. Even amongst planarian flatworms,
well-known for complete regeneration from tiny body fragments, some species have …

Regenerative abilities and their evolution in the different animal lineages have fascinated
generations of biologists. While some taxa are capable of restoring entire individuals from …

Naidids are tiny, transparent freshwater oligochaetes, which are well known for their ability
to propagate asexually. Despite the fact that sexually mature individuals and cocoons with …

Germ cells (reproductive cells and their progenitors) give rise to the next generation in
sexually reproducing organisms. The loss or removal of germ cells often leads to sterility in …

The evolution of regenerative capacity in multicellular animals represents one of the most
complex and intriguing problems in biology. How could such a seemingly advantageous trait …

Animals vary widely in their ability to regenerate, suggesting that regenerative ability has a
rich evolutionary history. However, our understanding of this history remains limited because …

Background Annelids exhibit remarkable postembryonic developmental abilities. Most
annelids grow during their whole life by adding segments through the action of a segment …
