In the wake of the Harvey Weinstein scandal, the extent that women must confront unwanted male attention is at the forefront of our consciousness. But a new study released in October shows that human females are not the only ones that must fend off unwanted advances. In a study published in Proceedings of the Royal Society B, scientists found that bottlenose dolphins have evolved to protect themselves from fertilization from some of their male counterparts.
Male bottlenose dolphins form alliances of two to four dolphins in order to keep competitors away from females. When a female dolphin confronts such an alliance, the female often has no choice who she will mate with, and may mate with all of them.
When archaeologists uncovered a medieval grave on the island of Chapelle Dom Hue, off the west coast of Guernsey in the Channel Islands, they expected to find the remains of a long-departed human. Instead, they found a properly buried porpoise.
The grave, carefully cut into the rocky soil on a high point of the island overlooking the sea, was constructed with the same techniques used for human graves. It takes up valuable real estate on the small island. So what’s the explanation? At this point, researchers only have theories.
