A research team has clarified a mechanism of how retrotransposons, genetic elements that can 'jump around' chromosomes and are known drivers of evolution, preferentially insert in the centromere. A ...

Convergent evolution—where distinct species independently evolve similar traits or functions, such as the wings of birds and bats—has long fascinated biologists. Now, a research team led by Prof. Zou ...

Skeletons of the early horse-relative Eohippus (left) and modern Equus (right). From Animals of the Past by Lucas. During the early 20th century many biologists were considering a variety of ...

The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly ...

The history and diversity of life on earth are testimony to evolutionary processes that extend back to the dawn of time. The agent of change and diversification is natural selection acting over long ...

Monoamine neurotransmitters such as serotonin and dopamine play important roles in our cognitive and emotional functions. Their evolutionary origins date back to metazoans, and while the function of ...
