And you don't see the other design 'virtues' all over the place? you know what bad design is? the body works well and is a marvel.
Imagine for me that there is a mountain. It is an absolutely majestic, and awe inspiring mountain, like something you would see in Zion Canyon.
Now, imagine that I were to tell you that this mountain isn't natural, but is instead made by aliens.
Well, we don't really have anything made by aliens we can compare it to, but we have many natural mountains we can look at and see how it stacks up.
Well, it has plenty of signs of water and wind erosion. It's shape also looks very consistent when compared to other mountains next to it. It also is made of the same geographically consistent rock that surrounding mountains are made of. Now, I tell you that the aliens made this mountain this way to look like it's natural, but it's really artificial.
Does that mountain seem to you like it's made by aliens, or a product of nature?
See, when we look at aspects of the human form that aren't efficient or even all that useful, the point isn't in to say it's bad. The point is the find out why. Is it because we were just created that way, or is it because at one point in our past, we needed them, and they were useful then? That is the core of evolution, and how creatures change over time according to the way they have to interract with their environment.
Sure, being able to rotate our ears via darwin's tubercle would be cool! A lot of primates can do that, but we can't, even though we have that same structure on our body. Why should we have that same structure if we can't use it? What's the purpose?
Is it because we were made that way, or is it because at one time in our distant past, we could use it?
