Why are our ears shaped the way they are with all their weird ridges? Why aren’t they more simply shaped like a funnel?
In: Biology
Ears not only have to funnel sound into the ear, but their shape helps us determine from which direction the sound came. If they were perfect conical shaped funnels we’d have no way to determine if the sound came from in front of us or behind us, we’d only be able to determine if it were more on our left or our right.
By shaping the sound as it comes into the ear, its timbre changes and our brain can interpret the quality of the sound and translate it into positional information.
Of course they weren’t DESIGNED like this, but more that those organisms with odd shaped ears were able to better discern where threats were coming from and survive and pass on their weird shaped ears gene.
