Research statement:  How do complex behaviors and other evolutionary adaptations emerge from the molecular organization of cells and genomes?  I have addressed this question by asking another.  How has selection shaped genetic patterns to constrain "random" mutational mechanisms, thereby reducing the risk of severely deleterious mutation while increasing the probability of beneficial mutation?  Recent publications have reviewed evidence that supports a functional and evolutionary "tuning knob" role for tandem repetitive DNA.

"Ad astra per alia muscae."
(with apologies to John Steinbeck) 

The Lord in his wisdom made the fly
And then forgot to tell us why.

Flies were made so fools like me
Might wonder how such things could be --
With tiny wings and eyes
and brains
Evolved in such diversity.
