A: pregnancy in humans

DOLPHINS MAY KNOW IF YOU’RE PREGNANT: Some experts say dolphins might be able to detect a pergnant woman’s developing fetus by using echolocation. Dolphins perform echolocation by emitting sounds and listening to the echos that return– the proces helps them identify the shapes and locations of objects. Researchers say that anecdotal evidence suggests that dolphins take a special interest in pegnant women. The dolphins supposedly swim up to expecting women and make a buzzing sound near the woman’s tummy. Neuroscientist Lori Marino says that dolphins will put their snount against the skin of another dolphin and buzz in order to stimulate the other dolphin. Marino says, “I think it’s extremely plausible [dolphins] would be able to detect a fetus…you’d have to do a well-controlled study to make a definitive statement.” (Fox)
