We found that most transitions to land were accompanied by a large gene turnover, with many gene gains and reductions ...

Fri, May 2, 2025 at 12:00 PM UTC Those many millions of years have given birds time to evolve into some 11,000 species, and keeping track of all those species—not to mention their evolutionary history ...

Tree thinking is a pedagogical approach that emphasises the interpretation and construction of phylogenetic trees to elucidate evolutionary relationships. In the context of evolutionary biology ...

My colleague and I have published a new study of cactus flowers which may help explain the conundrum. For more than a century ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

A recent study reveals we have a long-lost relative which hung out with our more famous apelike ancestors about three million years ago. It turns out the human family tree is more complicated than we ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

Evolutionary algorithms have emerged as a robust alternative to traditional greedy approaches for decision tree induction. By mimicking the natural selection process, these algorithms iterate over a ...

Highly valued economically, ecologically and culturally, the white oak (Quercus alba) is a keystone forest species and is one of the most abundant trees across much of eastern North America. It also ...

Why do you have five fingers? Why not ten, or twenty, or one? Why do so many animals have five fingers? Five seems to be the perfect number for most hands. Oddly, the first vertebrates to come onto ...

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 ...
