(PhysOrg.com) -- When it comes to voter preference, the issues count. But some may pull the handle for a more primal reason: Physical fitness and stature against an opponent.
In research published in Proceedings of the National Academy of Sciences, assistant professor of biochemistry and molecular biology at Saint Louis University Mee-Ngan F. Yap, Ph.D., discovered new information about how antibiotics ...
A University of Rhode Island biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed.
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
The Krüppel-like factor and specificity protein (KLF/SP) genes are found across many species, ranging from single cell organisms to humans. This gene family has been conserved during evolution, because it plays a vital role ...
Natural selection can be an agonizingly long process. Some organisms have a way of taking matters into their own hands, or—in the case of the ant species Cerapachys biroi—mandibles.
(PhysOrg.com) -- A new analysis of extinct sea creatures suggests that the transition from egg-laying to live-born young opened up evolutionary pathways that allowed these ancient species to adapt to and thrive in open oceans.
Researchers at Harvard University have found that humans aren't the only ones who can groove to a beat -- some other species can dance, too. This capability was previously believed to be specific to humans. The research team ...
(Phys.org) —Comparisons between the stock market floor and a zoo are not far from the mark, according to a new study published today in the journal Proceedings of the National Academy of Sciences (PNAS).
It has been a basic principle of evolution for more than a century that plants and animals can adapt genetically in ways that help them better survive and reproduce.
