Evolutionary ties between humans and prehistoric animals – study published in “Nature”
The fresh-water polyp Hydra, a member of the over 600-million-year-old phylum Cnidaria, is famous for its virtually unlimited regenerative capability and hence a perfect model for molecular stem cell and regeneration research. This polyp, with its simple structure and radial symmetry, can help us understand how our body axes came to evolve. Scientists from Heidelberg and Vienna have brought this evidence to light through their research on the formation of new polyps in the Hydra through asexual reproduction. Their findings have now been published in the journal “Nature”.
