A population of Vasa2 and Piwi1 expressing cells generates germ cells and neurons in a sea anemone.

Germline segregation, essential for protecting germ cells against mutations, occurs during early embryogenesis in vertebrates, insects and nematodes. Highly regenerative animals (e.g.

Evolutionarily conserved aspects of animal nutrient uptake and transport in sea anemone vitellogenesis.

The emergence of systemic nutrient transport was a key challenge during animal evolution, yet it is poorly understood. Circulatory systems distribute nutrients in many bilaterians (e.g.
