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 ...

How do populations go from one genotype to another genotype if the intermediate phenotypes have lower fitness? The evolutionary forces that explain this make up the shifting balance theory. When ...

The family of disorders known as ataxia can impair speech, balance and coordination, and have varying levels of severity. Scientists have identified a new member of this group of conditions which is ...

Researchers have identified a remarkably small but critical piece of genetic code that helps determine how brain cells connect, communicate, and function. The discovery not only deepens our ...

Two infant boys whose bodies were overloaded with excess fluid have led UCSF pediatricians to the discovery of a new genetic disease. In the process, they have discovered a rare type of mutation where ...

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 ...

It's time for researchers to reconsider the current paradigm of cancer as a genetic disease, argues Sui Huang from the ...
