So how did this evolve over the past 1000 years? Selection pressure? The ancestor who could dive better had more children? Could feed his family better? Was it just one person with mutation that started it? Or, did the frequent exposure to deep diving triggered something in one generation that influenced the genes of their children (along the lines of Epigenetic magic)?
