That have literally nothing to do with evolution.

A common example is that of the malnourished animal due to a drought. The animal is not underweight because it's phenotype dictates that it be underweight. The drought is not caused by any sort of evolutionary process.

The proximate cause of the animal being underweight is malnourishment. The distal cause is the drought.

So, no, evolution is not always the source. And it is not necessarily the case that all things are sourced in evolutionary processes. The vast majority of the physical realm is not dictated at all by biological evolution.
