Why divergence? (in allopatry)• Null hypothesis

• Genetic drift (e.g., Puechmaille et al. 2011)

• Selection

• Habitat physical features

• Clutter (e.g., Odendaal et al. 2014)

• Humidity (e.g., Guillén et al. 2000)

• Morphology

• Acoustic environment (e.g., Gillam & McCracken 2007)

• Other species (Kingston et al. 2001*)

• Prey (Kingston & Rossiter 2004*)

Lande 1976 Evolution

• Little difference in means

• High variance can accommodate wide variation

Where could we find such estimates?In the genetics data

Hey & Nielsen 2007 PNAS

“ancestral” data, Clare et al. 2013 BMC Evol Biol

What other data do we have?

• Habitat physical features

• Clutter (e.g., Odendaal et al. 2014)

• Humidity (e.g., Guillén et al. 2000)

Armstrong & Kerry 2011 J Theor Biol

What is left?• Null hypothesis

• Genetic drift (e.g., Puechmaille et al. 2011)

• Selection

• Habitat physical features

• Clutter (e.g., Odendaal et al. 2014)

• Humidity (e.g., Guillén et al. 2000)

• Morphology

• Acoustic environment (e.g., Gillam & McCracken 2007)

• Other species (Kingston et al. 2001*)

• Prey (Kingston & Rossiter 2004*)
