On other lists I experienced that this often needs an explanation.

The mail headers can be shown by   View > Message Source   , then you
can see "In-Reply-To" and "References", this is the thread information.

If you e.g. send a mail from command line, you at least should copy the
"In-Reply-To" field to keep a thread.

If you _do not_ want to keep a thread, but send a new thread by using a
mail you received with Evolution, then use the "Forward" button of
Evolution.

Some people sort their mails by thread.

IOW the subject (often called "thread") isn't the information a mail
user agent does use for sorting by thread, there's additional
information in the email header.
