Neural stem cells drive lifelong eye growth in marine bristleworms
A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life – driven by a ring of ...
Lancelets, or amphioxus, are small worm-like marine animals that spend most of their lives buried in the sea floor, filter-feeding through jawless, ciliated mouths. The vertebrate affinities of these ...

Whole-genome duplications are rare evolutionary events in which all the chromosomes and genes of a species are doubled. This supplies new genetic material to the gene pool and can provide an ...

Animals can be divided into groups. We call this 'classification'. Classification allows us to group animals together depending on their similarities and differences. Animals are divided into two main ...
