Answer 1

You kinda answered your question already… other animals that are closely and less closely related to us have rounded ears… so why would we evolve differently? Humans with rounded ears successfully survived and reproduced… so now we still have rounded ears.
Given that we don’t need pointy ears for survival, we could evolve pointed ears only if we suddenly all decided to mingle and have babies only with people that have extremely pointed ears.
