Common Misconceptions
The DNA record and the fossil record are two separate sources of information about the past. While the fossil record provides a physical record of ancient organisms, the DNA record provides a genetic record. By combining these two records, researchers can gain a more comprehensive understanding of evolutionary history.
What Is the Difference between DNA and Fossil Record?
Stay Informed
At its core, the process of decoding ancient DNA involves extracting DNA molecules from fossilized remains and analyzing their genetic code. This is typically done through a process called polymerase chain reaction (PCR), which amplifies the DNA molecules to make them detectable. Once the DNA has been extracted and amplified, researchers can use a range of techniques to analyze its genetic code and draw conclusions about the evolutionary history of the species.
