Editing DNA sequencing (section)

=== Evolutionary biology ===
Since DNA is an informative macromolecule in terms of transmission from one generation to another, DNA sequencing is used in [[evolutionary biology]] to study how different organisms are related and how they evolved. In February 2021, scientists reported, for the first time, the sequencing of [[DNA]] from [[Carrion|animal remains]], a [[mammoth]] in this instance, over a million years old, the oldest DNA sequenced to date.<ref name="CNN-20210217">{{cite news |last=Hunt |first=Katie |title=World's oldest DNA sequenced from a mammoth that lived more than a million years ago |url=https://www.cnn.com/2021/02/17/world/mammoth-oldest-dna-million-years-ago-scn/index.html |date=17 February 2021 |publisher=[[CNN]] |accessdate=17 February 2021 }}</ref><ref name="NAT-20210217">{{cite journal |last=Callaway |first=Ewen |title=Million-year-old mammoth genomes shatter record for oldest ancient DNA – Permafrost-preserved teeth, up to 1.6 million years old, identify a new kind of mammoth in Siberia. |date=17 February 2021 |journal=[[Nature (journal)|Nature]] |volume=590 |issue=7847 |pages=537–538 |doi=10.1038/d41586-021-00436-x |pmid=33597786 |bibcode=2021Natur.590..537C |doi-access=free }}</ref>
