Decoded genome reveals secrets of pigeon traits and origins

Scientists have decoded the genetic blueprint of the rock pigeon, unlocking secrets about pigeons’ Middle East origins, feral pigeons’ kinship with escaped racing birds and how mutations give pigeons traits like feather head crests.

“Birds are a huge part of life on Earth, but we know surprisingly little about their genetics,” says Michael Shapiro, one of the study’s two principal authors and a biologist at the University of Utah. (more…)

A “Jumping Gene’s” Preferred Targets May Influence Genome Evolution

Baltimore, MD — The human genome shares several peculiarities with the DNA of just about every other plant and animal. Our genetic blueprint contains numerous entities known as transposons, or “jumping genes,” which have the ability to move from place to place on the chromosomes within a cell. (more…)
