Cannibals Make Stronger Kids

Scientists may have figured out why some females eat their male suitors. According to Science News, researchers studying Mediterranean tarantulas have found that cannibalistic female spiders have more offspring and lay eggs earlier than ones who didn’t eat their suitors. The extra time allowed the children of cannibals to grow bigger and stronger than their non-cannibalistic relatives. Some researchers speculate that the eaten males provide “prenatal nutrition” to the offspring.
