Negative Positive
Title: They almost had me fooled ...
Review: I was almost ready to seriously consider Margulis' and Sagan's revolutionary theory until I read Sagan's update, in which he writes "Because chromosome arrangements differ slightly in closely related mammal species (e.g., dogs and wolves) that no longer breed with each other ..."Everybody knows that wolves and domestic dogs CAN breed. You can buy wolf/dog hybrids from breeders such as http://www.dogpage.us/wolfdogs.htm.If one of the authors is this removed from common sense, I wonder about the rest of the theory. And I wonder if his mother knows what he's up to.
Is the review positive or negative?
