Pack Mentality Can Forgive Evolutionary Failure 2
You want to take it down but you’re too small, so now what? Sure, one would surmise that a species needs to go after smaller animals until it evolves to be bigger. However, even then it may always be too small. That means you need to figure out how to get more. One can accomplish this in a group where a bigger animal will feed a group of perhaps 5.
While they have to share, more will be available for all. Therefore, you are not sacrificing anything in doing this. Yet an animal like the tiger has grown big enough to be considered “Apex” and therefore capable of taking any animal down it pleases for food. It could rely upon a group, but it simply does not have to. Yet the Lion, also considered Apex, actually does still rely upon a group. Why? Simple, it’s insurance.
