Molecular evolutionary dynamics encompass the patterns and rates at which genetic material accumulates changes over time across diverse lineages. These dynamics are shaped by intrinsic factors such as ...

A major research study is challenging one of evolution’s most influential ideas: that most genetic changes that become permanent are essentially neutral. Researchers at the University of Michigan ...

Artificial intelligence allows tracing the evolution of genetic control elements in the developing mammalian cerebellum. An international research team led by biologists from Heidelberg University as ...

The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

Climate change is rapidly altering our environment—and posing major challenges for many animal species. Whether they can adapt depends largely on their genetic diversity. An international study ...

A reader emailed me to ask what I thought would be a good way to better understand some of the more technical posts I put up. First, two course notes which I've found useful as personal references: - ...

Mitochondria are the body's "energy factories," and their proper function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system acts like ...

Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...
