3. Fertilization of the egg in the upper part of the oviduct has always thought to be a means to naturally select the most-fit sperm, weeding out those less fit, unable to complete the journey. However, recent evidence has showed that sperm actually 'help' each other during the ascent by locking tails and pulling other sperm along towards the egg. Describe an alternative hypothesis for fertilization in the upper oviduct to the 'most fit sperm' hypothesis and how would you provide evidence?
