We used a mathematical model and experiments with laboratory populations of Escherichia coli to examine conditions for the evolution of plasmids conferring resistance to multiple antibiotics. In our ...

Conventional wisdom holds that sexual reproduction evolved because it enables organisms to shuffle, or recombine, different alleles (versions of a gene) in the next generation, producing the genetic ...

Animals from completely different branches of the tree of life, such as insects, worms and vertebrates, independently evolved similar genetic solutions to survive on land, according to a new study ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...
