Do dolphins have blow holes

- Evolution of the Dolphin/ Whale?
- Q: Before we get going I will say that I am a professional archaeologist and DO believe in evolution, so if thee are any whacko creationalists out there dont bother trying to answer...My question relates to ho whales and dolphins developed the ability to breathe through a hole on the neck/ head. It is my understanding that they were originally a land based mammal who like the rest of us, breathed through his mouth. If my knowledge of evolution is correct then the change from the lung bieng connected to the mouth to the lungs being connected to a valve on the opposite side of the head must have been a slow process. How could this have occurred if having a blow hole anywhere but behind the head would have been useless. I do not understand how it could have happened suddenly instead.Nice one Silverbirch, the funny thing is that Archaeologists do not tend to deal with the evolution of sea based mammals (or any mammals apart from humans) that sort of thing is generally left to biologists, thanks for your confidence. However your cynicism only seems to distract you from attempting to answer my question: It is irrelavent that the lungs are connected to the mouth or the nose, my question was how did the blow-hole develop? did the NOSE gradually migrate around the side of the head or does it seem to have happened suddenly? Have another try Silverbirch you might prove to be helpful after all...
