When Neandertals were first discovered nearly 170 years ago, the conceptual gap between their lineage and that of modern humans seemed vast. Initially scientists prejudicially believed that the ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...
