567-Million-Year-Old Fossils Reveal Oldest Animal Sex and Early Movement

Scientists report the oldest fossil evidence of sexual reproduction and locomotion in animals, dating to about 567 million years ago in Canada’s Northwest Territories as part of the White Sea assemblage. The finds, including Dickinsonia and Funisia, push the origin of animal sex back by 5–10 million years and reveal long‑lived offshore Ediacaran ecosystems; researchers aim to discover more specimens (perhaps a new species) at the site.

Wild Animal Mating: Intriguing Foreplay and Mobile Orgies

A scientific report reveals the diverse and inventive methods of sexual engagement among animals. Serotine bats have been found to mate without penetration, transferring semen through contact with the vulva. Dolphins engage in mass orgies on the move, while whales engage in foreplay for hours and exhibit homosexuality. Octopuses and cuttlefish have unique mating rituals, and walruses possess the largest penis bones among mammals. Birds also have peculiar mating behaviors, such as dunnocks inducing females to expel sperm from previous partners and female muscovy ducks evolving incompatible vaginas to avoid unwanted attention. Humans, too, are animals, and sex remains an improbable arrangement across species.
