A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
How do scientists know how old an object or human remains are?

It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew: that samples of moss could be brought back to life after being frozen in ice. That carbon dating deemed the moss to have been frozen for over 1,500 years.
Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands.
What methods do they use and how do these methods work?
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
Much of the information presented in this section is based upon the Stuiver and Polach (1977) paper "Discussion: Reporting of C14 data". 1890 wood was chosen as the radiocarbon standard because it was growing prior to the fossil fuel effects of the industrial revolution.
