Gossip Girl, dolphin-style: it’s all about who you know!  »

After a 20-year study, University of New South Wales biologists conclude that who your mother hangs out with is as important as who your mother is—at least in bottlenose dolphin communities. Who doesn’t love a good nature versus nurture study?! A: FASCISTS!

You can read the full text of the study online but I’m really into the Wired synopsis linked at the top because LESS READING. But yeah, this is all totally new data. These researchers studied 52 female bottlenose dolphins in the eastern gulf of Shark Bay, Western Australia. It looks like they chose these dolphins for their nature/nurture study because dolphins have a lot of things in common with us, such as, “Slow life histories characterized by late sexual maturity, long interbirth intervals, and extensive maternal care.” They say dolphins have those things in common with great apes, but that totally includes us and does that not sound familiar? Can’t you imagine those dolphins like totally screening their calls for mom? OMG cut the cord, Flipper!

The conclusion they reach is that “Female calving success depends on both genetic inheritance and social bonds. Moreover, we demonstrate that interactions between social and genetic factors also influence female fitness.” So essentially, DNA does matter but if you got them bad genes, your mom can offset that by hanging with the right crowd. Moreover, dolphins rule and I love them!
