Continuous stirring made early life-like RNA systems more extinction-prone, experiment shows
Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental conditions.
Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago
The discovery of fire was a major milestone in human evolution, giving our ancestors a way to stay warm, ward off predators, and eventually start cooking food. But exactly when this first happened is still intensely deb…
Epigenetic changes can be inherited without changing DNA in animals
Typically, the information encoded in DNA allows organisms to develop, function, and pass traits across generations. Yet DNA alone does not explain how genes are switched on and off in different cells and environments. …
