Ancestry & Evolution
The desire to understand our origins is primal. By examining our DNA over successive generations through the evolutionary process of inherited characteristics of human and animal populations–as well as from those species from which humans share a common ancestry–we can decipher our individual and collective past and develop medical innovations for the future.
