Adaptations don't tend to happen species-wide. It's usually that different groups of the same species have ended up in different environments that causes their adaptations to favor different traits, which accumulate until they're no longer the same.
Well said.
A lot of the fundamental misunderstanding about evolution seems to stem from a lack of understanding about the processes of natural selection and adaptation.
