How did researchers prove that some genes needed for tooth development are still present in chicken and that all it takes for teeth-like structures to be formed is the expression of a regulatory gene

Human Tooth Development

Explanation:

The development of tooth is commonly divided a some stages such as the arrange, the bud stage, initiation, the ringer arrange, finally maturation and the top stage. These teeth don't get through at this early stage, yet they've just shaped in utero After the infant is conceived, the enjoyment starts. By and large, teeth emit somewhere in the range of 4 and 6 months of age. The enamel organ otherwise called the dental organ, is a is a cellular aggregation found in a creating tooth and it lies over the dental papilla The dental follicle, otherwise called dental sac, is comprised of mesenchymal cells and filaments encompassing the veneer organ and dental papilla of a creating tooth They form into the alveolar bone, the cementum with Sharpey's strands and the periodontal tendon filaments separately
