Why the long neck?
... the U.K., and the U.S. came up with a list of 17,210 giraffe and 17,048 okapi genes. Comparing those sequences, the team found that the giraffe’s long neck is likely a result of mutations in two sets of protein-coding genes—one controlling gene expression patterns during limb development, the other ...
