A Puzzle?

[Gloria]

But wouldn't stopping or slowing evolutional changes just be one more expected alternative. One that has worked for a very long time with the Joshua tree and its pollinator moths.


The puzzle of biological diversity

New findings show that co-evolution between Joshua tree and its pollinator moths, such as the Tegeticula synthetica shown here, acts to reduce diversity within the species, rather than increase it as was previously thought. (Credit: Christopher I. Smith/Willamette Univ.)
