For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

Natural selection is an important evolutionary force that enables humans to adapt to new environments and fight disease-causing pathogens. However, the unique footprints of natural selection in our ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

Translation of L'évolution du vivant. An introduction to the study of evolution : General observations on the living world ; Biological evolution and its occurrences ; Interpretation of evolutionary ...

A groundbreaking study sheds light on the extraordinary evolution of anglerfish, a group of deep-sea dwellers whose bizarre adaptations have captivated scientists and the public alike. The research ...

The relationship between changes in the environment and evolution in wild animals is not a one-way street, according to a new study that includes a Penn State biologist. The study shows that ...

Millions thrive at high altitudes due to remarkable genetic adaptations. Tibetans, for instance, possess a gene variant allowing efficient oxygen use without dangerously thick blood. Andeans and ...
