Every year a mysterious phenomenon happens – the migration of the beautiful Monarch butterfly. But what does this happen? How do these lovely little creatures find their way, year after year, from Canada through western United States to Mexico? Researchers have been looking at the butterflies migration pattern and come up with an interest theory. They have unique internal clocks that help them regulate everything, from their sleep to their eating and reproduction and the sun plays a major part, which they use as a compass. But how is that possible?

When the researchers mapped molecular underpinnings of the butterflies' circadian clocks, they found a protein common in animals and insects. These proteins are what help the butterflies use the sun as their guide.You can find the entire article here http://aboutmyplanet.com/science-tec...ration-protein
