1番下の文のif not undertakenは 文法的にはどうなってるんですか？

Perhaps the strongest reason to think the planet could be home to Something is that over the past 20 years, we've learned that many inhabitants of Earth live in environments as peculiar as those on Mars. Here, some organisms exist inside rocks in the chilly wastes of Antarctica, or a mile deep in the ground. Others live in ice sheets, or breed in the strongest acids. If it can happen here, it could possibly happen on Mars, too. Finding life on Mars obviously would be thrilling. It would, in a small way, ease our (@). In addition, it might illuminate that great mystery, the origin of life on Earth. But the possibility of life on Mars also suggests that we should approach the place with caution. If something is living there, then bringing Martian rocks back to Earth could be a mistake if not undertaken very carefully.
