Beauty and Size: The Wild Sex Merry XXXMas Marathon Continues...


The next two episodes of Wild Sex are by far the most popular. In the first, aptly titled 'Beach Babes and Boob Jobs', I look at the concept of beauty in the animal kingdom and how this concept does not really apply to the human animal. In 'Size Matters', we take a look at some of the largest penises in the natural world, and scale them up for some pretty crazy visual drama. Can we say 40 foot long penis?! We also compare and contrast the evolutionary history of male primates when it comes to both penis length and testicle size. You might be surprised at how different apes 'measure up' to each other.

The views expressed are those of the author and are not necessarily those of Scientific American.
