Despite slang terms that imply otherwise, the human penis contains no bones. The same cannot be said for many of our closest evolutionary relatives: Chimpanzees and bonobos both have penis bones (a macaque one is pictured, left), also known as bacula.

To find out why some primates have the feature whereas others don’t, researchers traced the bone’s evolutionary history through time. The baculum first evolved between 145 million and 95 million years ago, as reported in the Proceedings of the Royal Society B. That means it was present in the most recent common ancestor of all primates and carnivores. Why some descendants, like humans, lost their bacula appears to be due to differences in mating practices: In primates, the presence of a penis ...

Witches finger grapes are custom made grapes that have a shape of their own. They are from the Californian breeding program International Fruit Genetics (IFG). Although it sounds like it could be GMO, it’s not - they are made through the hybridisation process of taking pollen from one plant and brushing it onto another plant. There are quite a number of these varieties now, in different colours as well. What's really interesting is that IFG also has a few other unusual varieties such as ‘cotton candy’, which when ripe acquires the taste of cotton candy – it’s very unusual, but also delicious. ...

Bullying is not easy to define, namely because there is no one way to bully. It comes in many forms, from physical playground scuffles to verbal attacks. Even governments have a hard time defining it, often referred to as a repeated behaviour with the intent to hurt someone either physically or emotionally. By this definitions, there are many ape and monkey bullies, too. In fact, any hierarchical society is likely to have bullies in its midst.

An unfortunate monkey at the bottom of the hierarchy is repeatedly attacked and picked upon by those higher up in the group - they are sometimes beaten up every day. Bullying amongst rhesus macaques, for example, seems to release tensions among the higher-ups. Bullying seems to reinforce their bonds, a ...

This is the first photograph taken of an orangutan using a tool to fish in Borneo. The photo captures a moment when this male was using the pole to catch fish trapped in the locals’ fishing lines.
