Is nature mostly a tinkerer or an inventor?
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 ...
Team discovers evolutionary mechanism that allows bacteria to resist antibiotics
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 ...
Higher hormone oxytocin levels in chimpanzees who share food
The ability to form long-term cooperative relationships between unrelated individuals is one of the main reasons for human's extraordinary biological success, yet little is known about its evolution and mechanisms. The hormone ...
Monkey business: Researchers discover primitive forms of wealth
(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).
First land animals kept fishlike jaws for millions of years, says biologist
Scientists studying how early land vertebrates evolved from fishes long thought that the animals developed legs for moving around on land well before their feeding systems and dietary habits changed enough to let them eat ...
Ant executions serve a higher purpose, research shows
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.
Diamondback moth genome provides new clues for sustainable pest management
An international research consortium, led by Fujian Agriculture, Forestry University (FAFU) and BGI, has completed the first genome sequence of the diamondback moth (DBM), the most destructive pest of brassica crops. This ...
Scientists decode watermelon genome
Are juicier, sweeter, more disease-resistant watermelons on the way? An international consortium of more than 60 scientists from the United States, China, and Europe has published the genome sequence of watermelon (Citrullus ...
New study finds evolution mostly driven by brawn, not brains
The most common measure of intelligence in animals, brain size relative to body size, may not be as dependent on evolutionary selection on the brain as previously thought, according to a new analysis by scientists.
