an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

not only is it colder, it also becomes darker, less salty, and more dense.
