News: Spider Monkeys kill male babies

Melissa Hogenboom wrote in BBC on 26/11/14 a new study made by observing a special mammal.

This new study has found that male SpiderMonkeys kill male babies from the same social group. And what’s more, they do this in order to prevent sexual competition between the males in the group. Even if it had been recorded five times it seems to be an alert for field researchers.

And they were right because the last long-term project recorded this infanticide more reiterative. So this behaviour is being more common every day. And it’s true to say that as many new males as much death threat will be.

Moreover, this investigation explains why Spider Monkeys female-biased sex ratios had.

This new contributes more information of infanticide in mammals. Over 119 species are known to commit this outrage and specially 35 of them are primate species.
