those of those that know me are aware of my random questions! todays is…humans can grow 2 sets of teeth-milk and 2nd ones. but why not a 3rd? crocodiles replace lost ones i believe. what changes that we cant produce a 3rd set?
i guess the answer lies in something to do with stem cell production…what makes a human unable to do what other animals can
there are some very clever folk on here. if they have the time to get their teeth into this i would be grateful for an explaination
