we sought to determine which nostril has the greater airflow most of the time. In line with the notion of a biological preparedness for sidedness consistency, it was hypothesised that left-handers have their left nostril as the dominant one (defined as the nostril with the greater airflow) significantly more often than their right nostril. For right-handers the opposite was predicted: the right nostril would most often experience the greater airflow...

Result: The present data support these predictions: for both left-handers and right-handers the nostril that had the significantly greater airflow was ipsilateral to the preferred hand almost 60% of the time.

The feature is present in approximately 10.4% of the population. This acuminate nodule represents the point of the mammalian ear. This atavistic feature is so called because its description was first published by Charles Darwin in the opening pages of The Descent of Man, as evidence of a vestigial feature indicating common ancestry among primates. However, Darwin himself named it the Woolnerian tip, after Thomas Woolner, a British sculptor who had depicted it in one of his sculptures and had first theorised that it was an atavistic feature.

many women when falsely accused [of adultery by their husbands] will lop off their index or pinky fingers at the first or second joint. This practice is quite common: of the fifty women with whom I conducted life history interviews, ten of them had one or two finger joints missing. Indeed this practice by Huli women is so pervasive that children say they make a point of hiding all knives and axes whenever their parents argue, not only to prevent them from injuring each other, but to prevent their mothers from lopping off their fingers. Like suicide, finger-lopping is motivated by anger and indignation, but it is highly performative as well; for example, one is supposed to maintain enough presence of mind to hurl the finger at one's accuser and yell something like, "keba biba haro, inaga ki bi pugu ngerogoni" (In order to cut off/finish my anger, I'm cutting off my finger and giving it to you.)
