Are there differences in DNA between humans of today and humans from 2000 years ago?
Are there any significant differences in our genome compared to the genes of our ancestors from 1000-2000 years ago?
And if there are significant differences, do they result in significant differences in phenotypic traits?
While most of the genome between early humans and modern humans are conserved. There are polymorphisms that are significantly more common in early humans vs modern humans. With human genetics small changes can result in significant genetic diversity.
