Evolution refers to changes in the genetic makeups of populations across time. Evolutionary processes occurring in different populations ultimately led to the current and past diversity of life on earth. Evolutionary studies investigate the details of evolutionary processes on multiple levels and scales of biological diversity, utilizing a variety of scientific methods. Some QBioS program faculty develop computational and statistical algorithms to efficiently analyze data to extract evolutionary meaningful parameters or species relationships. Other QBioS program faculty use evolutionary principles to engineer novel biomolecules for industrial applications.
