Sep. 27, 2022 —Scientists have discovered that a well-preserved fossilized worm dating from 518 million years ago resembles the ancestor of three major groups of living animals. Measuring half-an-inch long, the ...
Nov. 2, 2022 —An exceptionally well-preserved collection of fossils discovered in eastern Yunnan Province, China, has enabled scientists to solve a centuries-old riddle in the evolution of life on earth, revealing ...
July 1, 2022 —Using high quality molecular data, researchers have re-investigated a long-standing question about the position of two phyla of small aquatic invertebrates -- Kamptozoa and Bryozoa -- on the ...
May 26, 2022 —Even the smallest marine invertebrates -- some barely larger than single-celled protists -- are home to distinct and diverse microbial communities, or microbiomes, according to biologists. The study ...
Apr. 30, 2021 —The marine worm Ramisyllis multicaudata is one of only two such species possessing a branching body, with one head and multiple posterior ends. The researchers discovered that the complex body of ...

June 21, 2023 —In nature, smaller animals often attach themselves to larger ones to 'hitch a ride' and save energy migrating large distances. Researchers show how microscopic Caenorhabditis elegans worms ...
Aug. 27, 2020 —A half-a-billion years old fossil species of marine animal sheds light on how the anatomies of the two main types of an animal group called the hemichordates are related, and provides new evidence in ...
Sep. 11, 2020 —Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An ...
Dec. 29, 2020 —Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, scientists have shown that while haemoglobin appeared independently in several species, it actually ...
