Could Earth have become tidally locked around the Sun, like the Moon is around Earth?

The implications for life on Earth are fascinating if this were to happen.

It's not a past thing, it's a future thing. Over long enough time, this is the preferred configuration. The amount of time this would take for the Earth would be much longer than the expected lifetime of the sun. The time for Earth to get locked to the moon is faster, but still over billions and billions of years.
