Since Darwin's time, the phenomenon known as flower constancy -- i.e., where insects consistently visit the same flower type even when many others are also present...
Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.
Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make...
An archaeological study of human settlement during the Final Palaeolithic revealed that populations in Europe did not decrease homogenously during the last cold phase of the...
Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked...
More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research has revealed.
A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on...
Researchers have uncovered a complete Quina technological system in the Longtan site in southwest China. The discovery challenges the widely held perception that the Middle Paleolithic...
Scientists uncovered how whole-genome duplication emerges and remains stable over thousands of generations of evolution in the lab.
Major milestone reached in digital Cuneiform studies: Researchers present an innovative tool that offers many new possibilities.
