(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, ...
