ADVANCE FOR WEEKEND EDITIONS OF JAN. 26 - In an April 7, 2011 photo researcher Chris Smith checks blooms to see if field assistant Candace Fallon will be able to introduce Yucca moths to blooms on Joshua trees in the Mojave desert during research on April 7, 2011. The iconic plant of the Mojave Desert also provides a perfect example of what scientists call coevolution. The Joshua Tree and the Yucca moth have developed together and now they depend on each other for reproduction. (AP Photo/Las Vegas Review-Journal, Jessica Ebelhar)
