Anatomy in games

What I've learned: 

• To a biological scientist, this evolution mimics what we observe in nature; a process of hundreds of thousands of minuscule changes, which result in increasingly more complex and sophisticated organisms

• Studies have shown that a known face can be distinguished from a resolved photograph comprising only 50 pixels

• The human form is most clearly recognized by its generally upright position with a spherical head protruding superiorly and a central cylindrical trunk which bifurcates into two long cylinders inferiorly, which turn communicate with the ground

Opinions: 

• You have to get the whole structure right or something could go wrong

• Creating characters that look more realistic is the best way to evoke genuine emotion and reaction from an audience

Question: 

• How far will animators go with the realism in their animation?
