I have a question about bootstrapping:
The way that I understand it is that each number represents how well a given node is supported. So in the diagram presented, we can see that the "Seal-Bear-Cat" clade is fairly well supported with a bootstrap value of 87. From that, the "Seal-Bear" clade has a bootstrap value of 95, making it quite well supported within the larger clade.
My question is this: Does that 95 for the "Seal-Bear" clade refer to the idea that that given relationship is a true 95, and therefore very well supported, or is it a value of 95 within 87, making it a true value of somewhere closer to 83 for the overall tree?
