Investigating the effect of cannibalism on light tolerance In this experiment, these people tested whether light tolerance could be transferred through chemical compounds in a species of flatworms. This idea was based off the fact that flatworms could apparently still have memories even if cut in two. What these people wanted to investigate was whether certain "memories" or acquired traits could be retained in a dead worm cut in half and transferred to another worm without the trait being lost. They conducted the experiment by first splitting the worms into two groups. One group of worms was exposed to light, and thus forced to become light tolerant. Another group of worms was not exposed to light. After roughly a week, the group of worms
