Large Tides May Have Driven Evolution of Fish Towards Life on Land

Big tidal ranges some 400 million years ago may have initiated the evolution of bony fish and land vertebrates. This theory is now supported by researchers who, for the first time, have used ...

The Rhythm of Change: What a Drum-Beat Experiment Reveals 211Ʊ Cultural Evolution

Living organisms aren't the only things that evolve over time. Cultural practices change, too, and in recent years social scientists have taken a keen interest in understanding this cultural ...

War Songs and Lullabies Behind Origins of Music

Love is not the primary reason humans developed music. A new evolutionary theory of the origins of music argues more evidence supports music coming from the need for groups to impress allies and ...

Sentinels of Ocean Acidification Impacts Survived Earth's Last Mass Extinction

Two groups of tiny, delicate marine organisms, sea butterflies and sea angels, were found to be surprisingly resilient -- having survived dramatic global climate change and Earth's most recent ...

Primate Brain Size Does Not Predict Their Intelligence

A research team has systematically investigated the cognitive abilities of lemurs, which have relatively small brains compared to other primates. Conducting systematic tests with identical methods ...

Genome of Alexander Fleming's Original Penicillin-Producing Mold Sequenced

Researchers have sequenced the genome of Alexander Fleming's penicillin mould for the first time and compared it to later ...

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 ...

Placing Barthelonids on the Tree of Life

Researchers have categorized barthelonids, a group of microscopic anaerobic flagellates, as an early branching Metamonada lineage based on their genetic identity and mitochondrial evolutionary ...

Genome Duplications as Evolutionary Adaptation Strategy

Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Biologists made this discovery in their ...

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 ...

Computational Study of Famous Fossil Reveals Evolution of Locomotion in 'Ruling Reptiles'

Scientists used three-dimensional computer modelling to investigate the hindlimb of Euparkeria capensis -- a small reptile that lived in the Triassic Period 245 million years ago -- and inferred that ...

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 organism known as archaea. However, evidence of a ...

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

New research has led to the discovery of world's oldest animal sperm inside a tiny crustacean trapped in amber around 100 million years ago in ...

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 raid their way across Europe and beyond. Now ...

Paleontology: The Oldest Known Sperm Cells

An international team of paleontologists has discovered giant sperm cells in a 100-million year-old female ostracod preserved in a sample of amber. Clearly, the tiny crustacean had mated shortly ...

DNA Unlocks a New Understanding of Coral

A new study challenges more than 200 years of coral classification. Researchers say the 'traditional' method does not accurately capture the differences between species or their ...

Over a Century Later, the Mystery of the Alfred Wallace's Butterfly Is Solved
