Researchers have discovered a 100-kilobase segment of DNA missing from the agouti signaling protein (ASIP) gene in gibbons. The ASIP gene plays a role in lipid metabolism and energy homeostasis, but its deletion may have helped gibbons adapt to arboreal niches. Future studies will examine the physiological effects of this deletion.
