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 ...
Scientists have traced hidden pathways through animal evolution by comparing thousands of genomes and following pieces of chromosomes that have survived for hundreds of millions of years. The study ...
We humans have long viewed ourselves as the pinnacle of evolution. People label other species as "primitive" or "ancient" and use terms like "higher" and "lower" animals. This anthropocentric ...
“Terrible Lizards”—That’s the literal translation of the term Dinosauria, coined by Sir Richard Owen in the 19th century to describe the colossal bones early paleontologists were unearthing. For a ...
One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...
Phylogenomic analysis harnesses genome-scale data sets to reconstruct the deep branches of the animal tree of life, resolving longstanding debates about the relationships among major lineages such as ...
