A very interesting study has just been released on the rate of murderous interpersonal relationships within genetic groups done by Jose Maria Gomez at the University of Granada in Spain.
This study asserts that there seems to be a very high rate of murder within certain species groups of critters and that human beings are pretty well up there, though not as bad as we once were.
According to this study during the medieval period you could reasonably count on 120 people per 1,000 being murdered during their lifetime, the average lifetime being markedly briefer back then that it is now.
The current murder rate for human beings worldwide is said by this study to be abut 13 per 1,000, based on WHO information.
The study concludes that there is an inherited tendency towards murderous behavior, but notes that it can be greatly modified over time by social pressure and cultural and government functions.
It notes that lemurs, chinchillas and baboons murder each other at a rate of well over 100 per 1,000 population.
Serious interpersonal violence within the killer whale population is almost non-existent, though the sample available for study is small. Bats and anteaters are also remarkably peaceful critters within their own species.
