How to find out when a line appeared in a file in a Git repository?

Question

git

There is a file in the Git repository. I need to find out when and why a certain line appeared (or disappeared) in it. The command
git log -p -- FileName>Log.txt
gives the entire history of the file, and by searching for Log.txt I can catch all the commits with the required time, but I want only them to be displayed immediately. Unfortunately --grep only searches the description fields, not the contents of the changes. Maybe there is some other tricky key that will do what you need?
