A bird swoops toward a bright orange-and-black moth resting on a leaf in the Amazon. It pulls up at the last second. The ...

Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

Researchers at the Technion have discovered how changes in genetic regulatory sequences can lead to alterations in the form and structure of animals—even when genetic regulatory systems are stable and ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Population genetics examines how genetic variation is distributed within and between groups of organisms and how this variation changes over time under the influence of evolutionary forces. Core ...

Evolutionary paradox solved: Technion scientists found that stable genetic systems can still evolve through multiple molecular changes in redundant enhancers. Fruit fly case study: In Drosophila ...

Evolution is traditionally associated with a process of increasing complexity and gaining new genes. However, the explosion of the genomic era shows that gene loss and simplification is a much more ...

Plant molecular evolution offers key insights into how coding and regulatory changes shape the diversity of form and function across the plant kingdom. The ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths ...
