Texas A&M biologist Christine Merlin, with the help of research assistants like Sierra Popp (below, left), is developing genetic tools and new approaches to better understand the genetic basis behind Monarch butterfly migration -- a fascinating and arduous journey she believes is tied to circadian clocks within the insect's antennae.

LIKE CLOCKWORK: Texas A&M Biologist Says Butterfly’s Epic Journey Tied to Its Antennae

"And if we can show this is the case and that the circadian clock is involved, we can now start to understand the genetic program that is allowing the migratory behavior."
