A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most ...

The great effect that pathogens have exerted on the human genome is demonstrated by positive selection for traits such as sickle-cell hemoglobin (Sabeti et al., 2006). Natural human defenses have ...

can significantly contribute toward maintenance of a reasonable level of integrity in the genome of other species in the long term. If negative selection is too strong for the whole population ...

With the flurry of media attention surrounding the race to sequence the genome, it often seems as if the myriad genome facts and news items floating around could fill up a couple of telephone books.

The domestication of maize is one of the greatest examples of humankind's impact on evolution. Early farmers' pre-industrial plant breeding choices turned corn from a nearly inedible crop into the ...

Protein-coding versus noncoding genes When deciding the number of genes in the human genome, Human Genome Project researchers initially counted protein-coding genes—regions of chromosomal DNA that are ...

It continues 25 years of research at deCODE genetics into how new diversity is generated in the human genome, and its relationship to health and disease. The new map, appearing today in the online ...

Dairy cows in Nevada have been infected with a new strain of bird flu, marking the second strain detected in herds since ...

Each genome is duplicated multiple times and is ... major evolutionary theories—Fisher's fundamental theorem of natural selection and Susumu Ohno's neofunctionalization by gene duplication ...

Genome and mutations DNA replication is carefully controlled to preserve the genetic information. However, changes in the genome do sometimes occur. These changes are known as mutations.

Genome Spotlight is a monthly column for The Scientist’s Genetics & Genomics newsletter that highlights recently published genome sequences and the mysteries of life they may reveal. Christie is a ...

Key findings highlight the role of horizontal gene transfer, the incorporation of foreign bacterial genetic material into the beetle genome, which is thought to be the result of earlier symbioses.
