(Phys.org) —A team of European researchers working at École polytechnique fédérale de Lausanne (EPFL) in Switzerland has created an artificial compound eye that is comparable to those in insects such as the fruit fly. ...
An extraordinary find allowing scientists to see through the head of the 'fuxianhuiid' arthropod has revealed one of the earliest evolutionary examples of limbs used for feeding, along with the oldest nervous system to stretch ...

(Phys.org)—A team of Canadian researchers has found that one species of barnacles mate by ejecting sperm into seawater while another catches it – a process known as spermcasting. Prior to this research, scientists had ...
Complex brains evolved much earlier than previously thought, as evidenced by a 520-million year old fossilized arthropod with remarkably well-preserved brain structures. Representing the earliest specimen to show a brain, ...

Millipede legs grow in an unexpected way, according to new research. Previously, it was thought that when a millipede molts (sheds its exoskeleton), it grows new segments on the end of its body without legs. Then after the ...
