***PCM in #6 means  phylogenetic comparative method ***

The method of independent contrasts relies on running odds ratio tests. compares the best possible tree overall with the best possible constrained tree allows evolutionary biologists to use phylogenetic comparative methods for studying adaptations. relies on the logic of bootstrap analysis. Can PCMs PCMS identify the cause of adaptation? Depends what PCM method is used. Only when convergent evolution happens. No, because they are correlative in nature. Yes.

Solution

Answer 1. the correct option is Allows evolutionary biologists to use phylogenetic comparitive methods for studying adaptations. the method of independent contrasts is an approach of PCM.

Answer 6. Correct option is - DEPENDS WHAT METHOD IS USED.

Phylogenetic comparitive method could identify the cause of adaption based on what method, or what approach is being used. Two approaches are there for PCM, one inclusdes the evolutionary history of some character based on genotype and phenotype and the other one includes the inference of process of evolutionary branching leading to adaptation. So using this approach the cause of adaptation can be inferred by using PCM.
