Скачать или смотреть How Do Scientists Determine An Individual’s Age At Death?

We have spoken of many ancestral burials and many fossils found. How they died, when they died and even at what age they died. Have you ever wondered though, how the age of the individuals that have passed were determined? Well, if you were curious about that, we have answers for you.
First feature that gives scientists a hint of the individuals age are the teeth. If fossils finds include teeth than it makes the work of the scientists just a teeny bit easier because teeth can tell us how old individuals were when they died, especially if they died young. This is because teeth appear in a certain sequence and at particular ages.
We know that our first deciduous ‘milk teeth’ or ‘baby teeth’ begin to appear at around six months of age. These gradually fall out during childhood about the age of 6 and are replaced by permanent or ‘adult teeth’. All our teeth appear in a certain sequence and each type of tooth appears at a particular age. For example,when we talk about baby teeth, lateral incisor appear at about 6-11 months of age, canine at about 16-20 months and first molar about 10-16 months.
And for our adult teeth, the ages at which they appear are central incisor at about 6-8 years, lateral incisor 7-9 years, canine 9-12 years, first premolar 10-12 years and so on. So, most of the information about an individual’s age is gathered by looking at the types of teeth visible above the jaw surface or the gum line. That is the first step of examination. Additional information comes from examining the degree of root development deep within the jawbone
