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.
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.
Connecting the Dots
Anna Azvolinsky | Aug 1, 2014 | 8 min read
Extending her initial studies of social wasps, Mary Jane West-Eberhard has spent her career probing the evolutionary relationship between social behavior and developmental flexibility.

Unearthing the Evolutionary Origins of Insect Wings
Jef Akst | Apr 4, 2022 | 6 min read
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo
How to Create a Successful Fish Tale?
A. J. S. Rayl | Aug 19, 2001 | 10+ min read
More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear
