One of the most debated issues in human history has come to an astounding end. Wait, no, that was that other story. This one is about fetus yawning.
Nonetheless, scientists have disagreed upon the legitimacy of fetal mouth openings actually being yawns, and not just early forms of those duh moments you have when you’re watching an engrossing film and you think no one is watching until someone throws a balled-up piece of toilet paper at you and it sticks to the gathered drool accumulated in your beard. Also, it happens when you’ve been typing for a long time. Anyway, a study published in PLOS ONE proves that these are indeed yawns, but little more can be established at this point, though theories will lead to further research.
A team of researchers from Durham and Lancaster Universities, led by Dr. Nadja Reissland, of Durham University’s Department of Psychology, performed 4D scans on eight female and seven male fetuses from 24 to 36 weeks. Video footage of the scans were studied, with the various, and numerous, mouth openings getting most of the attention. The time durations were recorded, and over half of the instances were long enough to qualify as yawns. They’re not just yawning during the boring parts.
