A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the ...

Two types of carbohydrates are important to plants—structural carbohydrates (which form cell walls) and nonstructural ...

In a new article published in Frontiers in Bioinformatics, biologists Dr. Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that ...

University of Michigan researchers have used an AI tool to demonstrate that birds in the group Passeriformes evolved in rapid ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

Adam Rutherford salutes a show that finally links the spectacle of natural history with the science that explains it ...

What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago, yet humans—the only intelligent, technological species we know of in the ...

In a recent study published in the journal Scientific Reports, researchers investigated the associations between the lifespan of different dog breeds and their evolutionary history through ...

Evolutionary biologists have long believed that the human-biting mosquito, Culex pipiens form molestus,evolved from the bird-biting form, Culex pipiens form pipiens, in subways and cellars in northern ...

Fungi represent one of the most ancient and diverse branches of the eukaryotic tree of life, with origins tracing back over a billion years. Through the integration of molecular phylogenetics, fossil ...
