To Understand the Machinery of Life, This Scientist Breaks It on Purpose

By tinkering with some of life's oldest components, astrobiologists hope to find clues about how life emerged. In a recent article researchers report an unexpected discovery, hinting at an effect ...
Although overhunting led to the demise of some prehistoric megafauna after the last ice age, a new study found that the ...

Mutations May Have Saved Brown Howlers from Yellow Fever Virus

From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international ...

Primate Voice Boxes Are Evolving at Rapid Pace

Scientists have discovered that the larynx, or voice box, of primates is significantly larger relative to body size, has greater variation, and is under faster rates of evolution than in other ...

An Ancient Association? Crickets Disperse Seeds of Early-Diverging Orchid Apostasia Nipponica

A professor presents evidence of the apparently unusual seed dispersal system by crickets and camel crickets in Apostasia nipponica (Apostasioideae), acknowledged as an early-diverging lineage of ...

Faster Rates of Evolution Are Linked to Tiny Genomes

Inside every cell lies a genome - a full set of DNA that contains the instructions for building an organism. Across the biological world, genomes show a staggering diversity in size but scientists ...

Dinosaur Relative's Genome Linked to Mammals: Curious Genome of Ancient Reptile

Biologists have sequenced the genome of the tuatara, a lizard-like creature that lives on the islands of New ...

Study Clarifies Kinship of Important Plant Group

Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study has now somewhat closed this knowledge ...

Angels in Disguise: Angelfishes Hybridize More Than Any Other Coral Reef Species

A new study highlights the remarkably high incidence of and tendency toward hybridization in the angelfish family (even between divergent species), more so than in any other group of coral reef ...

Between Shark and Ray: The Evolutionary Advantage of the Sea Angels

Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team has now investigated the origin of this body shape. The results illustrate how ...

Humans and Flies Employ Very Similar Mechanisms for Brain Development and Function

A new study has shown that humans, mice and flies share the same fundamental genetic mechanisms that regulate the formation and function of brain areas involved in attention and movement ...

Oriole Bird Hybridization Is a Dead End

A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock's Oriole, found in the western half of North America. In the other corner: ...

First Gene Knockout in a Cephalopod Achieved

Biologists have achieved the first gene knockout in a cephalopod using the squid Doryteuthis pealeii, an exceptionally important research organism in biology for nearly a century. The team used ...

Ancient Mountain Formation and Monsoons Helped Create a Modern Biodiversity Hotspot

Researchers examined the plant life in the China's Hengduan Mountains, the Himalaya Mountains, and the Qinghai-Tibet Plateau. Using DNA to build family trees of species, they learned that the ...

Immune Functions Traded in for Reproductive Success

Researchers have investigated the phenomenon of sexual parasitism in deep-sea anglerfish. The scientists show that this very rare mode of reproduction is associated with the loss of adaptive ...

Remote Islands: Stepping Stones to Understanding Evolution

Researchers have investigated evolutionary and ecological changes in ants in the South Pacific archipelago of Fiji to examine a controversial theory for how evolution occurs on ...

Geological evidence suggests the known dinosaur groups diverged early on, supporting the traditional dinosaur family ...

Butterfly Genomics: Monarchs Migrate and Fly Differently, but Meet Up and Mate

A new study confirms that while the eastern and western butterflies fly differently, they are genetically the ...

Gorilla Relationships Limited in Large Groups

Mountain gorillas that live in oversized groups may have to limit the number of strong social relationships they form, new research ...

Biologists Zero in on Cells' Environmental Sensing Mechanism

Evolutionary and developmental biologists report that they have identified a molecular mechanism that allows an organism to change the way it looks depending on the environment it is exposed to, a ...

Research Could Save Years of Breeding for New Miscanthus Hybrids

As climate change becomes increasingly difficult to ignore, scientists are working to diversify and improve alternatives to fossil-fuel-based energy. Renewable bioenergy crops, such as the perennial ...

New Paper Squares Economic Choice With Evolutionary Survival

Unlike businesses or governments, organisms can't go into evolutionary debt -- there is no borrowing one's way back from extinction. This can lead to seemingly irrational economic choices ...

Artificial Intelligence to Identify Individual Birds of Same Species

Humans have a hard time identifying individual birds just by looking at the patterns on their plumage. An international study has now shown how computers can learn to differentiate individual birds ...

Genetic Mutations Help MRSA to Become Highly Resistant to Antibiotics

Scientists have found that genetic mutations in MRSA allow it to evolve and become more resistant to antibiotics such as ...
