how to estimate phylogeny without using DNA sequences?

I am new to bioinformatics, I am reading ‘Analysis of Phylogenetics Second Edition and Evolution with R’ from Emmanuel Paradis.

I can create phylogeny from DNA sequences, by first calculating the distances and then using (ie nj() function).

My question is: if instead of DNA I have trait data (ie height and weight of species), how can I estimate a phylogeny? (is the same process valid? somehow calculate distances and pass that to nj()?)
