With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Interactions between mitochondrial and nuclear genomes have further-reaching effects on physiological function, adaptation, and speciation than previously appreciated.
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
