Scientists are only stumped because they are stupid enough to think that everything has to have an explanation. The fact is that we evolve in rather a haphazard way, that traits and behaviours that are useless, meaningless or puzzling can be preserved throughout the selection process, just so long as they do not adversely affect the ability to raise viable progeny.
And since evolution has provided primates with a plastic brain, the selection process is not in control of what stuff it does.
The evolutionary imperative of a male chimp is to implant his seed in a female, and hers is to care for her young until they can repeat the process.
Chimps do this very well - what they do in their spare time is up to them.
99% of human behaviour has basically nothing to do with reproductive success; such as me writing this post, whilst watching shit TV.
Why scientists are stumped, stumps me.
