having evolved into a broader protest against alleged police brutality

[lagoo]

1. The bill was eventually withdrawn, but the demonstrations continued, having evolved into a broader protest against alleged police brutality, and the way Hong Kong is administered by Beijing.

Regarding the underlined part, does it mean that the demonstrations continued and have evolved into a broader protest?

2. The bill was eventually withdrawn, but the demonstrations continued, evolving into a broader protest against alleged police brutality, and the way Hong Kong is administered by Beijing.
If I use ‘evolving’ to replace ‘having evolve’ as showed above, would it mean ‘the demonstrations continued and was still in the process of evolving into a broader protest’?

I think there is no difference in the two versions. Saying something has evolved does not mean the process has stopped.

The demonstrations continued, but their purpose had changed.

You've understood the basic difference, yes.

The perfect aspect is a way to suggest that the evolution into a broader protest was complete at the time the bill was withdrawn.

 

[SoothingDave]

1 states that the evolving had happened prior to the bill being withdrawn. 2 suggests that the evolving was a reaction to the withdrawal. They're not the same.

Thank you all for your succinct replies.
Based on your interpretation, can I rewrite the first sentence as:
The bill was eventually withdrawn, but the demonstrations, which have evolved into a broader protest against alleged police brutality, continued.

 

[SoothingDave]

"have evolved ... continue" or "had evolved ... continued."

 

[lagoo]

"have evolved ... continue" or "had evolved ... continued."

Sorry about my mistake.
If I rewrite the first sentence as:
(3) The bill was eventually withdrawn, but the demonstrations, which had evolved into a broader protest against alleged police brutality, continued, and the way Hong Kong is administered by Beijing.

and if (3) is compared with my original (1),
(1) The bill was eventually withdrawn, but the demonstrations continued, having evolved into a broader protest against alleged police brutality, and the way Hong Kong is administered by Beijing.

will the meaning keep the same?

You've lost the thread. Do you see something missing in the part I've underlined? (An unnecessary comma makes sentence 1 harder to follow.)

It should have been:The bill was eventually withdrawn, but the demonstrations, which had evolved into a broader protest against alleged police brutality and the way Hong Kong is administered by Beijing, continued.

Is the meaning of the above remain the same, though a bit awkwardly worded?

Yes. That's a complicated sentence. Well done!
