University of Utah biologists discovered that a mutation in the ROR2 gene is linked to beak size reduction in numerous breeds of domestic pigeons. Surprisingly, different mutations in ROR2 also underlie a human disorder called Robinow syndrome. The ROR2 signaling pathway plays an important role in the craniofacial development of all vertebrates.

New research is shedding light on how the nasal passage in dolphins and whales shifts during embryonic development, from emerging at the tip of the snout to emerging at the top of the head as a blowhole. The findings are an integrative model for this developmental transition for cetaceans.
Research from Wellesley College shows that despite being a clonal insect species, weevils use gene regulation to adapt to new food sources and pass down epigenetic changes to future generations.
A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species. The research centers on a process known as sex chromosome dosage compensation.
New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution - underlining that species can diversify surprisingly quickly under certain conditions.
Boker Tachtit in the Negev is a crucial archaeological site for studying the spread of Homo sapiens out of Africa and the subsequent demise of Neanderthals. Using techniques so sophisticated that they can date grains of sand, Weizmann’s Prof. Elisabetta Boaretto and colleagues have shown that previous dating of the site was incorrect – and that early humans and Neanderthals cohabitated at the site.
Michigan State University ecologists led an international research partnership of professional and volunteer scientists to reveal new insights into what’s driving the already-dwindling population of eastern monarch butterflies even lower.
Add this to the list of real-life spidey senses: Harvard researchers have shown that jumping spiders are able to tell the difference between animate objects and inanimate objects -- an ability previously known only in vertebrates, including humans.
Researchers took 3-D printed reconstructions of fossil cephalopods to actual water tanks (including a swimming pool) to see how their shell structure may have been tied to their movement and lifestyle.
Scientists at Oak Ridge National Laboratory and the University of Wisconsin–Madison have discovered that genetically distinct populations within the same species of fungi can produce unique mixes of secondary metabolites, which are organic compounds with applications in medicine, industry and agriculture.
A new paper appearing in Biology Letters describes the oldest-known fragmentary bat fossils from Asia, pushing back the evolutionary record for bats on that continent to the dawn of the Eocene and boosting the possibility that the bat family's "mysterious" origins someday might be traced to Asia.
A Case Western Reserve University researcher is leading an interdisciplinary global team that will use state-of-the-art technology to tackle an ancient question: How did ecological factors affect the evolution of our ancestors millions of years ago? The possible answers so intrigued the W. M. Keck Foundation that it awarded Armington Professor Beverly Saylor and her colleagues a $1.2 million grant to explore them.
Female vampire bats establish an egalitarian community within a roost rather than a society based on a clear hierarchy of dominance that is often seen in animal groups, a new study suggests.
Since the discovery of the first fossil remains in the 19th century, the image of the Neanderthal has been one of a primitive hominin.
Using a well-preserved Heterodontosaurus skeleton and high-powered x-rays, an international team of researchers has discovered that not all dinosaurs breathed in the same way. The findings give scientists more insight into how a major group of dinosaurs, including well-known creatures like the triceratops and stegosaurus, evolved.
Dinosaurs were generally huge, but a new study of the unusual alvarezsaurs show that they reduced in size about 100 million years ago when they became specialised ant-eaters.
A study led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates. The work reveals that mating-related traits can be just as important to how organisms adapt to their climates as survival-related traits.
Elephants and their forebears were pushed into wipeout by waves of extreme global environmental change, rather than overhunting by early humans, according to new research.
Fire can put a tropical songbird's sex life on ice.
Deposit contains exceptionally preserved fossils of soft-bodied, juvenile organisms from the Cambrian
A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of known Homo skulls, scientists now say this skull represents a newly discovered human species named Homo longi or "Dragon Man." Their findings, appearing in three papers publishing June 25 in the journal The Innovation, suggest that the Homo longi lineage may be our closest relatives--and has the potential to reshape our understanding of human evolution.
Analysis of recently discovered fossils found in Israel suggest that interactions between different human species were more complex than previously believed, according to a team of researchers including Binghamton University anthropology professor Rolf Quam.
