Neanderthals had naughty sexual life
Paris, Nov. 3: Neanderthals may be lampooned as slack-jawed low-brows who could just about wield a heavy club on a good day, but in one important respect they outperformed us: in the number of sex partners.
So says an unusual study which suggests finger length can indicate promiscuity among hominins, as the ancient family of humans is known.
The researchers led by Mr Emma Nelson of the Liverpool University, north-western England, looked at fossilised fingers from four hominin species. Mr Nelson’s theory is based on the ratio between the length of the index finger as compared to the ring finger. High levels of in-utero androgens increase the length of the fourth finger in relation to the second finger, which thus lowers the ratio. They are also linked with promiscuity, as per this work.
