Not waving, not really pointing

Little Miss is 15 months old (halfway to 16months), and she is a very active and social kid. She loves exploring and has been developmentally ahead with all things except pointing and waving.

I keep hearing/reading that these can be signs of autism. She makes great eye contact, has started saying a few words, affectionate and claps etc.

But she hardly ever waves and very rarely points.

Does anyone have insight on this? Should we be worried or get her evaluated at some point?
