I was just going by the link you provided.
If it must be from the "Webster's 1913 Dictionary" section ...
The word "evolve" is used when the word "develop" is the equivalent.
This was to be my conclusion. Prior to that, I decided to take a look at my favorite online dictionary. I started with the entry for develop and went directly to the alphabetical list of "related words."
I did not find the word "evolve."
I will try again:
1. "Webster's 1913 Dictionary" section contains the Webster's definition for the subject word
2. "Webster's 1913 Dictionary" section does NOT provide synonyms for the subject word
3. "WordNet Dictionary" does NOT contain the Webster's definition for the subject word
4. "Related Words" section DOES contain all the synonyms AND related words that Webster-dictionary.org considers to be BOTH synonymous and related to the subject word
I once owned a 1913 Webster's dictionary.
There is no reason to put my favorite online dictionary within quotes.
The ignore list is as follows with a few dedication-songs to be determined:
what if (Everything In Its Right Place
Gneiss girl (Mother of Pearl

1. Well duh. As I mentioned (and quoted) last post the Webster's 1913 section does use the words in question to help define the other as if they are synonyms of each other in certain contexts, and many other dictionaries will explicitly say so. Your ignoring of the Webster's 1913 definitions I've quoted is noted.
2. That is correct, and you may have noticed because of your objection I stopped referencing the synonyms from your link after my initial post on the topic.
3. Well duh. As I explained last time my initial post included that section because it was part of the link you provided, and again when you complained that I was looking at the wrong dictionary in your link my subsequent post ignored that section and only looked at the Webster's 1913 section (and the related words section).
4. Just looking at the Webster's 1913 section and the related words section this does not appear to be the case. For example look at the entry on "develop", and one of the ways it defines the word is "to unfold", the second entry starts off with the phrase "to unfold gradually", the third entry starts off "to advance; to further; to prefect", and several of the entries use the word "growth", yet these words/phrases are not in the related words section of said word. I think if you set aside any attached significance to the related words section you would agree that phrases like "to advance" and "growth" are related to the word "develop". For example, 'my oratory skills have developed' means the same basic thing as 'my oratory skills have advanced', or 'my oratory skills have grown'. Do you disagree? - the related words section does disagree if we take your assertion as valid.
The phrase "to prefect" is an odd definition for develop if I say so myself - even looked it up wondering if there was some left-field definition I was not aware of, and it appears this is a typo in the dictionary. The word "perfect" is in the related words section and would make much more sense if the entry said "to perfect" and not "to prefect". My point here is that it is possible that this online dictionary is not perfect, and may not be 100% comprehensive.
I'll end by saying that I do believe your initial assessment that the two words are often equivalent is correct. I would also urge the usage of human judgement before backtracking on that assessment on the sole grounds that the related words section in a single dictionary do not deem them related despite that the definitions of said dictionary do, never mind all the other dictionaries out there or how people in the real world use those words.
