‘Sponges saved life on earth’

This 30 July 2019 video says about itself:

How Earth’s First, Unkillable Animals Saved the World

They have survived every catastrophe and every mass extinction event that nature has thrown at them. And by being the little, filter-feeding, water-cleaning creatures that they are, sponges may have saved the world.

Thanks to Franz Anthony and Julio Lacerda for their wonderful illustrations of sponges and snowball earth and other things. You can find more of their work here.
