Do Epigenetic Changes Influence Evolution?
Katarina Zimmer | Nov 1, 2022 | 10+ min read
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.
Revolutionary Repurposing
Neil Shubin | Jun 1, 2020 | 3 min read
Evolution needn’t make improbable leaps to facilitate transitions into uncharted biological territory. Adapting new uses for existing structures works just fine.
Tentacles test tenets of evolution
Elie Dolgin | Nov 17, 2008 | 3 min read
Novel genes, rather than regulatory DNA, underlie the evolution of morphological traits, according to research published today (Nov. 17) in __PLoS Biology__. The new linkurl:study;http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pbio.0060278 reports that genes found in simple freshwater animals -- but not in any other evolutionary lineage -- can drive changes in body plan, and stokes the flames of a long-standing debate among evolutionary developmental biologist
Retroelements Guide Adaptation

Hybrid Animals Are Not Nature’s Misfits
Ashley Yeager | May 1, 2021 | 8 min read
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.
