Whole genome sequencing of North American song sparrows has revealed the genetic underpinnings for a stunning range of body sizes found throughout the bird's westernmost range-an adaptation that may make the birds more resilient to climate change.

<p>Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America’s most familiar and beloved songbirds. This discovery also provides insights into this species’ capacity to adapt to the challenges of climate change. The study, published today in <em>Nature Communications, </em>used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutation...
