I got thinking: according to the DVD epilogue, the electromagnetism is why babies can't be born on the island and, in fact, that problem extended to the polar bears and other Dharma test animals.
So....if the electromagnetism is creating problems for pregnancies for animals as well, how did the wild boar have babies...or any other mammals on the island for that matter?
Anyone still think they weren't just making shit up as they went along?
