A new study theorizes that evolution ticks at different speeds, especially when a big group of organisms first appears.

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

Phylogenetics and molecular evolution lie at the heart of understanding the origins and diversification of life. By constructing phylogenetic trees, scientists map the evolutionary relationships ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Researchers at LSTM have shown that under certain circumstances evolution can be highly predictable, especially in terms of how creatures become resistant to dangerous toxins. Biologists looking at ...

Molecular evolution investigates the processes that drive changes in genetic material over time. It encompasses the generation of mutations—whether through DNA replication errors, damage or other ...
