A scientist has discovered that bioluminescence may not have originated as a means to ward off predators, but instead evolved as a way to survive in harsh climates — at least in one millipede. The finding, based on the discovery of a millipede that hadn’t been seen in 50 years, shows that even the seemingly most complex and intricate of traits can be traced in evolution as small steps leading to a complex feature we see today.
