Evolution of teeth in humans turns to smaller teeth

Tweet

The scientist and researchers had found that most obvious change to our jaws will be the disappearance of wisdom teeth, which serve no use to modern humans, and which already have low occurrence rates among some ethnic groups. But aside from this, we can also expect our teeth to grow smaller. Throughout the evolution of man, there has been a general trend towards smaller teeth. Evidence has shown that in the last 100,000 years alone, our teeth have halved in size. No longer having any reason to accommodate such huge gnashes, our jaws have also shrunk. We can expect this trend to continue into the foreseeable future.?? I wonder whether this will happen to animals to too. But I am sure there will be change in them too
