It does hint at common ancestry so it is "evidence" of evolution.
how does adaptations give evidence for evolution?

No, they are not evidence for ontogeny recapitulating phylogeny.
Polyploidy in plants, for one instance the doubling of chromosomes at mating, is direct evidence not only for evolution but for speciation as well. I fact many to most modern angiosperm species are developed this way.
Indirect Evidence of Evolution - is looking for signs of the results of evolution. - is evidence that can be used to deduce what you are trying to understand.

Evolution
Physiological similarities suggest the species evolved from the same ancestor.
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.

Buildings
Fossils provide amazing evidence for the theory of evolution and the long history of life on Earth.
Monkeys
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.
