I think that growing extra teeth in most humans would be a bad idea. Even if people are missing an average of 4 teeth, what would happen to their mouth if they had those extra teeth BEFORE their bad teeth were pulled? their teeth would probably crowd and/or become impacted. then in the long run they would need even more teeth pulled. Many people need to get their wisdom teeth removed due to lack of space. why would we want even more teeth? I could see it being helpful if the teeth could comfortably refrain from surfacing until needed, but is that even possible?

I think that evolution will and has help us adapt when we need to. In order to eat the food that we have now, we have the kinds of teeth in our mouths. If the type of food changes over time, then the type and structure of the teeth and mouth will follow.

I think are teeth develop different due to our way of life –and what we eat. A single row of teeth works for us, but I do think the study is interesting. And it would be helpful if there was a way to “regrow” teeth for humans.

i am not exactly sure if it is a good thing to have just a single row of teeth or to have more. people do loose teeth from multipule factors but people are also getting their wisdom teeth pulled out. in some ways we could use the extra teeth and in other ways extra teeth would do nothing except cause more trouble. i don’t think we would really need to have and extra row of teeth. we eat just normaly and we don’t need to worry about trying to hunt down our food and not getting injured in the process.

What a unique article. It is quite interesting how mammals’ teeth grow differently than other species. Humans grow a single row of teeth possibly from the foods we eat and how we chew. Sharks can eat multiple fish at a time and need that food kept in their mouths.

I think that it is totally understandable that teeth grow in a single line because it is evolution that makes our bodies form the way they are. We have specific teeth so that we can eat many kinds of food and that helps us to survive in different environments. I think a single row of teeth is better for humans. This experiment is easily understandable and it is good to see that it was conducted.
