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.

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.

Gene controls beak morphology
Maria Anderson(manderson@the-scientist.com) | Sep 2, 2004 | 3 min read
Scientists have pinpointed a molecular basis for size variations in the beaks of Galapagos finches', a phenomenon observed by Charles Darwin more than a century and a half ago.In this week's issue of Science, Harvard University developmental biologist Cliff Tabin and colleagues identified bone morphogenetic protein (Bmp)-4 as a key player in the pathway controlling avian beak development. His team includes Peter and Rosemary Grant, whose research endeavors on the islands were recorded in Jonatha

A Recurrent Theme
Ricki Lewis | Jun 10, 2005 | 1 min read
I just had dinner with a Drosophila geneticist, an historian of science specializing in taxonomy, a paleontologist whose expertise is trilobites, and a developmental biologist who is using sea anemone genome data to map mutants, the opposite of the way things were done when I was in graduate school. By now, we all pretty much know one another, and when I looked over at the other tables, I noted the eclectic mixes. Everyone here is talking about it, how this meeting is like no other. AAAS (Am
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
