ANN ARBOR—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 ...

In the children’s game telephone, a whispered phrase like “I ate a pear” can quickly become “I hate bears” as it moves down a line of players. As genes are passed down from parents to offspring, they ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research ...

Human aging is not what natural selection failed to prevent. It is what happens when selection simply has nothing left to act ...

In a recent study published in Nature Genetics, researchers performed an allelic-level single-cellular multi-omics evaluation of hematopoietic stem/progenitor cells (HSPCs) obtained from individuals ...

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex. Thousands of miles from home in ...

Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...
