Answer

Yes, this would change things quite a bit since the two pathways which we know can be detected by their tendency to fix proportionally more carbon-12. Without a bias, we would not be able to detect a pathway using biomarkers.

Work Step by Step

Consider first how we do detect evidence of biological carbon fixation: a bias in which isotope is fixed. Then consider if we would be able to detect biological fixation without this bias.
