Yes, evolutionary relationship is linked with classification. Organisms which are more closely related i.e., they have some ancestorial history are placed comparatively more closer than species which are not related.

For e.g.- humans & apes are placed in the same family-
Hominidae during classification.

Similarly, lion, cat & tigers are also placed in the same family- Felidae.

It is so because humans & apes and cat; lion & Tigers have common ancestorial histories. They all are inter-related. But there is no relation between humans, apes & cat, lion & tigers that is why they are placed in different families.
