Barely mentioned in the scientific media, heating from sonic waves can activate genes:

Using mice engineered with a bioluminescent gene containing a heat-sensitive stretch of DNA, they focused high-intensity ultrasound pulses on a 0.5-millimeter-wide patch of the mice’s legs, heating up that area just below the skin’s surface to about 43 degrees Celsius (109 degrees Fahrenheit). Light given off revealed that the gene became active.

Call me stupid, but could there be a link between why dogs have evolved to hear ultrasounds (for no purpose that I could find), and the ability of these waves to activate genes, and evolution?
