To anyone with a basic understanding of evolution, it should seem puzzling that deadly genetic diseases, passed on from one generation to the next, haven’t eradicated themselves by now. Having one ...

The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...

The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors. Mayr believed that genes interacted ...

Early evolutionists believed that the genetic basis of adaptation was micromutational. This view was supported by Ronald Fisher's classical mathematical analysis (of 1930) of his 'geometric model' of ...

Scientists led by a Children's Hospital of Pittsburgh geneticist have found new evidence that a category of genes known as pseudogenes serve no function, an important finding that bolsters the theory ...

This is a preview. Log in through your library . Abstract Confronted with variable environments, species adapt in several ways, including genetic differentiation, a jack-of-all-trades strategy, or ...

Lewontin's paradox — the much larger variation in species abundance than in genetic diversity — is closer to being explained. The reproductive strategy of species has an impact on genome-wide ...

The debate over COVID-19's origin is focused on two theories, that humans were first infected by a wild animal or that the virus leaked from a lab. Scientists say the natural transmission theory has ...
