Fourth Finger in Competitive Romance

Fingers are connected to mental and somatic functions. This less known fact has been published with the research backing. On wonders how far this true. Most times what research says is not seen in the personal lives. In the latest research twist, fourth finger gets connected to competitive and romance outputs. The Times of India writes on 20 November 2009 A longer fourth finger in comparison to the second finger suggests the species tend to be highly competitive and promiscuous, says a new study. Finger length ratio is a reliable predictor of how a primate will behave socially, say scientists who have been running the tape-measure over groups of baboons and gibbons. Such ratios are governed by exposure in the womb to androgens like testosterone, which figure importantly in the development of masculine characteristics such as aggression and strength. High levels of androgens, such as testosterone, increase the length of the fourth finger in comparison to the second finger. The scientists used finger ratios as an indicator of the levels of exposure to the hormone and compared this data with observed social behavior in primate groups, Scienceagogo reported. The researchers, from the University of Liverpool, found that Old World monkeys, such as baboons and rhesus macaques, have a longer fourth finger in comparison to the second finger, which suggests that they have been exposed to high levels of prenatal androgens. These species tend to be highly competitive and promiscuous. Other species, such as gibbons and many New World species, have finger ratios that suggest low levels of prenatal androgen exposure. These species were monogamous and less competitive than Old World monkeys. Great Apes, such as orangutans and chimpanzees, expressed a different finger ratio. This suggests that early androgen exposure is lower in this groups compared to Old World monkeys. Lower androgen levels could explain why Great Apes show high levels of male cooperation and tolerance. The research may help scientists understand the development of human sociality. “Finger ratios do not change much after birth and appear to tell us something about how very early androgens affect adult behavior, particularly behavior linked to mating and reproduction,” noted researcher Emma Nelson
