      The DNA I extract from bones gets sequenced – that means we can find out something about the animal that lived thousands of years ago. For example, we can tell if the sample was male or female, or if it came from a recently reduced population. If we sequence enough different genomes of the same species, we can start to say things about populations, like how they change through time or if we find evidence of selection or genetic changes due to domestication.
