It's all a matter of perspective, other animals would think the same about us for such concepts as:

• Menstruation - Heck, the whole pregnancy thing is basically body horror to almost anything but mammals regardless of the benefits. Even many woman think as such.
• Our spines are a mess. They are not made for walking upright, and our knees are just as bad.
• Choking on food is simply not possible for many animals. Why would you route air and food through the same place?

Now, compare this to let's say a jellyfish, which didn't even change that much for millions of years because it just works.
