Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be. Chromosomes, the bundles of DNA that star in the mitotic ballet ...

Scientists have found that harmful mutations accumulating in the fire ant social chromosome are causing its breakdown. Scientists from Queen Mary University of London have found that harmful mutations ...

The centromere is necessary for the transport of chromosomes during cell division and, therefore, for the correct ...

How do living things evolve? What is the myriad of processes by which generic variations in a population affect organisms' survival and allow reproduction in an ever-changing environment? Why do these ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of ...

Scientists have proposed an addition to the theory of evolution that can explain how and why genes move on chromosomes. The hypothesis is called the SNAP Hypothesis. Scientists at Uppsala University ...

The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...

Variations in the properties of arabica coffee, such as in taste, caffeine content and disease resistance, are determined by chromosome mutations, according to a recent study. But are these findings ...
