@ Nefer the link is at the bottom of the article you posted.It's titled "Scientists Discover Mother Monkeys Who Kill Their Babies". The article about infanticide among the Mustached Tamarin was a very interesting read. One must read this article with an open mind in order to understand the natural instincts of this species.
I read the article on the monkeys...it was interesting to see that the male presence also influenced the survival rate of the children as seemingly does in the human spectrum. I am going to read deeper
What a nice trick from Liu Li.... and the monkey science says a lot about the state of so called black people and family. Even with the father in the family, i still see massive menta-cide. One piece to a large puzzle is construction of family.
