Discovery of Microbes With Mixed Membranes Sheds New Light on Early Evolution of Life

Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event between bacteria and another single-celled ...

Scientists Identify Gene Family Key to Unlocking Vertebrate Evolution

New research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode ...

World's Largest DNA Sequencing of Viking Skeletons Reveals They Weren't All Scandinavian

Invaders, pirates, warriors - the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and ...

World's Oldest Animal Sperm Found in Tiny Crustaceans Trapped in Myanmar Amber

Y Chromosomes of Neanderthals and Denisovans Now Sequenced

An international research team led by Martin Petr and Janet Kelso of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has determined Y chromosome sequences of three ...

Researchers find that the molecular mechanisms underlying tail regeneration in West African lungfish are similar to those seen in amphibians, suggesting the trait evolved in a common ...

New Insights Into Evolution of Gene Expression

The long-term expression of genes in vertebrate organs predisposes these genes to be subsequently utilized in other organs during ...

Study Finds Missing Link in the Evolutionary History of Carbon-Fixing Protein Rubisco

A team has discovered a missing link in the evolution of photosynthesis and carbon fixation. Dating back more than 2.4 billion years, a newly discovered form of the plant enzyme rubisco could give ...

Warmer, Acidifying Ocean Brings Extinction for Reef-Building Corals, Renewal for Relatives

A new study finds that reef-building corals emerged only when ocean conditions supported the construction of these creatures' stony skeletons, whereas diverse softer corals and sea anemones ...

Early Cambrian Fossil: Bizarre Half-Billion-Year-Old Worm With Tentacles Solves Evolutionary Mystery

A half-a-billion years old fossil species of marine animal sheds light on how the anatomies of the two main types of an animal group called the hemichordates are related, and provides new evidence in ...

Catching Genes from Chlamydiae Allowed Complex Life to Live Without Oxygen

Researchers has discovered a new group of Chlamydiae - named the Anoxychlamydiales - living under the ocean floor without oxygen. These have genes that allow them to survive without oxygen while ...

Two Major Microbial Groups Living Deep Underground Can't Breathe

A new scientific study has revealed unique life strategies of two major groups of microbes that live below Earth's surface. These groups, originally thought to rely on symbiotic relationships ...

How Dinosaur Research Can Help Medicine

The intervertebral discs connect the vertebrae and give the spine its mobility. The disc consists of a cartilaginous fibrous ring and a gelatinous core as a buffer. It has always been assumed that ...

Bird Skull Evolution Slowed After the Extinction of the Dinosaurs

From emus to woodpeckers, modern birds show remarkable diversity in skull shape and size, often hypothesized to be the result of a sudden hastening of evolution following the mass extinction that ...

Survival of the Fit-Ish

It can be hard to dispute the common adage 'survival of the fittest'. After all, 'most of the genes in the genome are there because they're doing something good,' says a ...

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 ...

Evolutionary Theory of Economic Decisions

When survival over generations is the end game, researchers say it makes sense to undervalue long shots that could be profitable and overestimate the likelihood of rare bad ...

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 ...

Most Close Relatives of Birds Neared the Potential for Powered Flight but Few Crossed Its Thresholds

New research has resulted in an updated evolutionary tree of early birds and their closest relatives to reconstruct powered flight potential, showing it evolved at least three times. Many ancestors ...

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 ...

Origins of Life: Chemical Evolution in a Tiny Gulf Stream

Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists now report on a hydrothermal mechanism ...

DNA from an Ancient, Unidentified Ancestor Was Passed Down to Humans Living Today

A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ...

New Insight Into the Evolution of Complex Life on Earth

A novel connection between primordial organisms and complex life has been discovered, as new evidence sheds light on the evolutionary origins of the cell division process that is fundamental to ...

Faster Rates of Evolution Are Linked to Tiny Genomes
