A team of researchers at the Max Planck Institute for Heart and Lung Research, working with a colleague from Temple University, has found that transcriptional adaptation appears to play a role in inherited epigenetic changes.
Evolution by Darwinian natural selection is immensely powerful—both in nature and within laboratories. Using 'laboratory evolution', we can take an enzyme which combines random mutations and functional selection, and improve ...
