Why do Killer whales and similar sea creatures have perfectly straight teeth and humans have crooked teeth?
Most organisms in the animal kingdom have been here and evolving for a longer period of time then primates. Any organisms whose teeth were truly crooked to a fault would have been eliminated from the gene pool and animals especially ancient wild ones had very poor dentists, LOL. The crooked teeth individuals were removed from the gene pool over time and therefore the genes for better tooth structure and function survived and thrived. Also if you were to really compare a large sample of jaw structure of killer whales you would indeed notice differences in tooth patterns. Another fact is also remember killer whale teeth are shaped like cones so you can not really tell the front or back since they are round, therefore a tooth could be twisted 90 degrees right and would look the same.
