Sponges are among Earth's most ancient animals, but exactly when they evolved has long puzzled scientists. Genetic ...

After studying rocks more than 541 million years old, MIT scientists have found new evidence that some of Earth’s first ...

The sponge, which was not recognized as an animal until the 19th century, is now the simplest and most ancient group of animals to have their genome sequenced. In a paper appearing in the August 5 ...

Molecular clocks, which use the mutation rate of biomolecules to deduce how long ago two species diverged, and phylogenetics (the evolutionary relationships between species) can tell us when sea ...

African lungfish are incredible animals that survive in freshwater or on land. Research on lungfish has taught us more about how vertebrates made the transition from water to land, because their ...

It grows on glass sponges and helps create habitat for rockfish, shrimp, and crabs. Researchers from the University of Alberta have discovered a new type of sea sponge living off the coast of B.C.

Researchers have said that comb jellies branched from the rest of the animals before the sponge, a simple animal without complex cell types. The cornerstone of the study is the researchers' sequencing ...

The sponge, which was not recognised as an animal until the 19th century, is now the simplest and most ancient group of animals to have their genome sequenced. An adult sponge of the species ...

A team of researchers has published a draft genome sequence of the sea sponge, an organism that wasn't recognized as an animal until the 19th century. The genome gives insight into the origins of ...
