Afossil uncovered along the Yangtze River in China is forcing scientists to rethink not just the origins of sponges but also the way they search for the earliest traces of animal life. For decades, a ...
An "extraordinary" species of fossil sponge dating back 315 million years has been discovered near the Cliffs of Moher in County Clare. The fossil sponge, named Cyathophycus balori, measures 50cm and ...
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 ...
Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for ...
A team of scientists digging up some of the Earth’s oldest rocks has uncovered new chemical evidence that Earth’s first animals were likely ancestors of the modern sea sponge. The discovery relies on ...
