They Call Him Flipper...

According to a new study published in the Proceedings of the Royal Society B, dolphins are smart, says Helen Thompson at the Nature News blog. Researchers at Wayne State University used the recently sequenced genome of the bottlenose dolphin to shed light on the evolution of the animal's nervous system, but they also found several commonalities with other large-brained mammals, Thompson says. "Although the resulting sequence has gaps, the WSU team used it to flag some 10,025 genes with counterparts in the genomes of nine other mammals, including cows, horses, dogs, humans, and elephants," she adds. "They found 228 gene sequences that had changed significantly relative to other mammals." Using this information, researchers hope to study genes that could affect intellectual ability in humans, which could lead to a better understanding of cognitive functions.
