Suddenly, biologists have hundreds of complete genome sequences of our feathered friends. That wealth of data is revolutionizing understanding of bird biology and evolution.
There’s a reason the world has more hobbyist bird-watchers than, say, rodent-watchers: Birds are unusually fascinating creatures. Biologists aren’t immune to their charms — they’ve long been working to understand why and how the creatures come by their flashy colors, varied shapes, florid songs and intricate behaviors. Those aren’t easy questions to answer, given the thousands of genes — many of unknown function — in a typical bird genome. Searching for the gene or genes behind a given trait can feel like trying to map out a vast landscape with a dim flashlight… More about this great article in the link below…
