Reply to Cooperative sperm outrun loners in the mating race. In simulated reproductive tracts of animals like cattle and humans, the behavior increases the chances that groups of cooperative bovine sperm will outpace meandering loners as they race to fertilize a female egg cell, physicists report. by MistWeaver80
I'm curious what other implications this has evolutionarily speaking.
Are there any mechanisms by which sperm containing a high proportion of similar DNA will 'cooperate' (ie: altruism theories)
Could this behaviour be responsible for fraternal twins?
If this behaviour does indeed impart even a small advantage over individual sperm why isn't it the norm?

Reply to eli5 - How can the human body be composed of 70% water when it feels and behaves like any other solid? by Virtual-Structure447
Think about a Car Tire. It's composed of 70% air by volume but certainly doesn't feel like air does it? That is how much of a effect the other 30% can have.
